Applied Materials Introduces Materials Engineering Solutions for DRAM Scaling

  • New Draco™ hard mask material co-optimized with Sym3® Y etcher to accelerate DRAM capacitor scaling
  • DRAM makers adopting Black Diamond®, the low-k dielectric material pioneered by Applied Materials to overcome interconnect scaling challenges in logic
  • High-k metal gate transistors now being introduced in advanced DRAM designs to boost performance and reduce power while shrinking the periphery logic to improve area and cost
SANTA CLARA, Calif., May 05, 2021 (GLOBE NEWSWIRE) -- Applied Materials, Inc. today announced materials engineering solutions that give its memory customers three new ways to further scale DRAM and accelerate improvements in chip performance, power, area, cost and time to market (PPACt).
The Draco hard mask resolves this issue with a new material whose selectivity is more than 30 percent higher than conventional DRAM capacitor hard masks. It enables the deposition of a 30 percent thinner hard mask, thus decreasing the capacitor’s aspect ratio and easing the difficulty of the etch process.

The digital transformation of the global economy is generating record demand for DRAM. The Internet of Things is creating hundreds of billions of new computing devices at the edge which are driving an exponential increase in data transmitted to the cloud for processing. The industry urgently needs breakthroughs that can allow DRAM to scale to reduce area and cost while also operating at higher speeds and using less power.
Applied Materials is working with DRAM customers to commercialize three materials engineering solutions that create new ways to shrink as well as improve performance and power. The solutions target three areas of DRAM chips: storage capacitors, interconnect wiring and logic transistors. They are now ramping into high volume and are expected to significantly increase Applied’s DRAM revenue over the next several years.

Introducing Draco™ Hard Mask for Capacitor Scaling

Since over 55 percent of a DRAM chip’s die area is occupied by the memory arrays, increasing the density of these cells is the biggest lever for reducing cost per bit. Data is stored as charges in cylindrical, vertically arranged capacitors that need as much surface area as possible to hold adequate numbers of electrons. As DRAM makers narrow the capacitors, they also elongate them to maximize surface area. A new technology challenge to DRAM scaling has emerged: the etching of the deep capacitor holes threatens to exceed the limits of the “hard mask” material that acts as a stencil to determine where each cylinder is placed. If the hard mask is etched through, the pattern is ruined. Taller hard masks are not viable because as the combined depth of the hard masks and capacitor holes exceeds certain limits, etch byproducts remain and cause bending, twisting and uneven depths.


Applied Producer® XP Precision® Draco™ CVD

The solution is Draco™, a new hard mask material that has been co-optimized to work with Applied’s Sym3® Y etch system in a process monitored by Applied’s PROVision® eBeam metrology and inspection system that can take nearly half a million measurements per hour. The Draco hard mask increases etch selectivity by more than 30 percent which enables a shorter mask. Draco hard mask and Sym3 Y co-optimization includes advanced RF pulsing which synchronizes etching with byproduct removal to enable patterning holes that are perfectly cylindrical, straight and uniform. The PROVision eBeam system gives customers massive, immediate actionable data on hard mask critical dimension uniformity which is the key to capacitor uniformity. Applied’s solution provides customers with a 50-percent improvement in local critical dimension uniformity and reduces bridge defects by 100X, thus increasing yields.

“The best way to quickly solve materials engineering challenges with our customers is to co-optimize adjacent steps and use massive measurements and AI to optimize process variables,” said Dr. Raman Achutharaman, group vice president, Semiconductor Products Group at Applied Materials.



Bringing Black Diamond® Low-k Dielectric to the DRAM Market

A second key lever of DRAM scaling is reducing the die area needed by the interconnect wiring that routes signals to and from the memory arrays. Each of the metal lines is surrounded by an insulating dielectric material to prevent interference between data signals. For the past 25 years, DRAM makers have used one of two silicon oxides – silane and tetraethoxysilane (TEOS) – as the dielectric material. Continual thinning of the dielectric layers has reduced DRAM die sizes but created a new technology challenge: the dielectrics are now too thin to prevent capacitive coupling in the metal lines whereby signals interfere with one another causing higher power consumption, slower performance, increased heat and reliability risks.

The solution is Black Diamond®, a low-k dielectric material first used in advanced logic. With DRAM designs now experiencing similar scaling challenges, Applied is adapting Black Diamond to the DRAM market and making it available on the highly productive Producer® GT platform. Black Diamond for DRAM enables smaller, more compact interconnect wires that can move signals through the chips at multi-gigahertz speeds without interference and at lower power consumption.

High-k Metal Gate Transistors Bring PPAC Improvements to DRAM

A third key lever of DRAM scaling is improving the performance, power, area and cost of the transistors used in the periphery logic of the chip to help drive the input-output (I/O) operations needed in high-performance DRAM like those based on the new DDR5 specification.

Until today, DRAM used transistors based on polysilicon-oxide which were phased out in foundry-logic by the 28-nanometer node because extreme thinning of the gate dielectric allowed electrons to leak, thereby wasting power and limiting performance. Logic makers adopted high-k metal gate (HKMG) transistors, replacing the polysilicon with a metal gate and the dielectric with hafnium oxide, a material that improves gate capacitance, leakage and performance. Now memory makers are designing HKMG transistors into advanced DRAM designs to improve performance, power, area and cost. In DRAM as in logic, HKMG will increasingly replace polysilicon transistors over time.

This technology inflection in DRAM creates growth opportunities for Applied Materials. The more complex and delicate HKMG materials stack is challenging to manufacture, and in-vacuum processing of adjacent steps using Applied’s Endura® Avenir™ RFPVD system has become the industry’s preferred solution. HKMG transistors also benefit from Applied’s epitaxial deposition technologies such as Centura® RP Epi along with film treatments including RadOx™ RTP, Radiance® RTP and DPN which are used to fine-tune the transistor characteristics for optimum performance.

“Draco hard mask and Black Diamond low-k dielectric are being adopted by leading DRAM customers, and the first HKMG DRAMs are now being introduced,” added Dr. Achutharaman. “Applied Materials projects billions of dollars in revenue growth as these DRAM inflections play out over the next several years.”

Additional information about the growth outlook for these technologies is being provided at Applied’s 2021 Memory Master Class being held later today. For more information, please visit the investor page of our website at https://ir.appliedmaterials.com.

Imec and AIXTRON Demonstrate 200 mm GaN Epitaxy on AIX G5+ C

Imec and AIXTRON Demonstrate 200 mm GaN Epitaxy on AIX G5+ C for 1200V Applications with Breakdown in Excess of 1800V

LEUVEN (Belgium), APRIL 29, 2021 — Imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, and AIXTRON, the leading provider of deposition equipment for compound semiconductor materials, have demonstrated epitaxial growth of gallium-nitride (GaN) buffer layers qualified for 1200V applications on 200mm QST® substrates, with a hard breakdown exceeding 1800V. The manufacturability of 1200V-qualified buffer layers opens doors to highest voltage GaN-based power applications such as electric cars, previously only feasible with silicon-carbide (SiC)-based technology. The result comes after the successful qualification of AIXTRON’s G5+ C fully automated metal-organic chemical vapor deposition (MOCVD) reactor at imec, Belgium, for integrating the optimized material epi-stack.

Wide-bandgap materials gallium-nitride (GaN) and silicon-carbide (SiC) have proved their value as next-generation semiconductors for power-demanding applications where silicon (Si) falls short. SiC-based technology is the most mature, but it is also more expensive. Over the years tremendous progress has been made with GaN-based technology grown on for example 200mm Si wafers. At imec, qualified enhancement mode high-electron-mobility transistors (HEMTs) and Schottky diode power devices have been demonstrated for 100V, 200V and 650V operating voltage ranges, paving the way for high-volume manufacturing applications. However, achieving operating voltages higher than 650V has been challenged by the difficulty of growing thick-enough GaN buffer layers on 200mm wafers. Therefore, SiC so far remains the semiconductor of choice for 650-1200V applications – including for example electric cars and renewable energy.

For the first time, imec and AIXTRON have demonstrated epitaxial growth of GaN buffer layers qualified for 1200V applications on 200mm QST® (in SEMI standard thickness) substrates at 25°C and 150°C, with a hard breakdown exceeding 1800V. Denis Marcon, Senior Business Development Manager at imec: “GaN can now become the technology of choice for a whole range of operating voltages from 20V to 1200V. Being processable on larger wafers in high-throughput CMOS fabs, power technology based on GaN offers a significant cost advantage compared to the intrinsically expensive SiC-based technology.”

Key to achieving the high breakdown voltage is the careful engineering of the complex epitaxial material stack in combination with the use of 200mm QST® substrates, executed in scope of the IIAP program The CMOS-fab friendly QST® substrates from Qromis have a thermal expansion that closely matches the thermal expansion of the GaN/AlGaN epitaxial layers, paving the way for thicker buffer layers – and hence higher voltage operation.

Dr. Felix Grawert, CEO and President of AIXTRON “The successful development of imec’s 1200V GaN-on-QST® epi-technology into AIXTRON’s MOCVD reactor is a next step in our collaboration with imec. Earlier, after having installed AIXTRON G5+C at imec’s facilities, imec’s proprietary 200mm GaN-on-Si materials technology was qualified on our G5+ C high-volume manufacturing platform, targeting for example high-voltage power switching and RF applications and enabling our customer to achieve a rapid production ramp-up by pre-validated available epi-recipes. With this new achievement, we will be able to jointly tap into new markets.” Currently, lateral e-mode devices are being processed to prove device performance at 1200V, and efforts are ongoing to extend the technology towards even higher voltage applications. Next to this, imec is also exploring 8-inch GaN-on-QST® vertical GaN devices to further extend the voltage and current range of GaN-based technology.

Nanexa AB started the first clinical study with ALD based PharmaShell® at the Karolinska University Hospital

Nanexa AB (publ) today announces that the company has started its first clinical study with PharmaShell®, a phase I study in Nanexa's product project NEX-18, at the Karolinska University Hospital.


The study aims to show that the company's NEX-18 product, a long-acting formulation of azacitidine (the active substance in the drug Vidaza), provides the desired safety and pharmacokinetic profile. In the study, two doses of NEX-18 will be studied. The study will be conducted at Karolinska University Hospital in Stockholm and Akademiska Sjukhuset in Uppsala.

“The start of this study is a very big milestone in Nanexa's development. It is with great enthusiasm that we now see that the study is getting started. We expect the study to be completed during the third quarter.”, said David Westberg, CEO of Nanexa.

The NEX-18 product is being developed to improve the treatment of MDS (Myelodysplastic Syndrome), a form of hematological cancer that mainly affects the elderly. This is done by utilizing the unique properties of the PharmaShell® concept to create a controlled release depot formulation. Today's treatment means that injections are given at hospitals seven days in a row each month. The goal of the NEX-18 project is to simplify treatment by only having to give one injection. In addition to greatly simplifying for patients, Nanexa sees that NEX-18 will provide significant cost savings compared to current treatment.

“With the results of this study, we intend to continue the clinical development with a phase II study to achieve clinical Proof of Concept. After that, the goal is to run NEX-18 further towards commercialization, either through a license partner or as an own project, whatever option is deemed to create most value for Nanexa”, said David Westberg.

ALD – The coating technology behind the drug delivery system PharmaShell®

The technology used by Nanexa to manufacture the shells that make up PharmaShell® is Atomic Layer Deposition (ALD). In ALD, reactive gases are used which, with atomic layer by atomic layer, build up a surface coating with high precision. ALD has been used in the electronics industry for decades and is thus well established for larger scale production and automation.

ALD can also be used at low temperatures, down to room temperature, unlike other surface coating techniques which usually use considerably higher deposition temperatures, thereby risking inactivating the drug. A further advantage of ALD is that the coating is carried out under dry conditions, which makes it possible to coat drugs that are quickly dissolved in water or other solvents.

By building up an atomic layer for atomic layer with ALD, the thickness of the coating can be controlled with extremely high precision. Drug particles of various sizes and shapes can be coated since the only thing required for coating to be formed is that the reaction gases can reach the surface.
About Nanexa AB (publ)

Nanexa AB is a nanotechnology drug delivery company focusing on the development of PharmaShell®, a new and groundbreaking drug delivery system with great potential in a number of medical indications. Within the framework of PharmaShell®, Nanexa has partnership agreements with among others, AstraZeneca.

Highlights of Prof. Erwin Kessels’ Recent Webinar on “Plasma-Assisted Atomic Layer Deposition: From Basics to Applications” Organized by the American Vacuum Society (AVS)

On the 10th of February, 2021, Prof. Erwin Kessels from Eindhoven University of Technology, Netherlands, delivered a 4-hour long webinar, full of highly valuable content, on Plasma-Assisted (Enhanced) Atomic Layer Deposition (PAALD/PEALD). For those who missed this wonderful opportunity to have an insight into one of the most advanced deposition processes in the semiconductor chip production line today, Abhishekkumar Thakur, Associated Technology Analyst with BALD Engineering AB has come up with some interesting highlights and key takeaways from Prof. Kessels' webinar from when we took part:


February 10, Erwin Kessels will present an AVS Webinar: Plasma-Assisted Atomic Layer Deposition: From Basics to Applications. Learn more at https://avs.swoogo.com/webinar_pald

Interesting Highlights and Key Takeaways

1. The current deposition wafer fab equipment market size for ALD has grown as big as or even bigger than that for PVD (Physical Vapor Deposition), but still less than that for CVD (Chemical Vapor Deposition)

2. Semiconductor processing plasmas exist under non-equilibrium conditions, i.e., the electrons present in the plasma are heated by the applied electric field up to a temperature of 50,000 K (~5eV) as opposed to the relatively low gas temperature (300-500 K) due to the low pressures. This is the reason that PEALD becomes useful in the deposition of the high-quality thin-films on thermally fragile substrates/structures, e.g., plastic, foil, photoresist, etc.

3. Electron Energy Distribution Function (EEDF) together with the electron impact cross-section with the events occurring in the plasma (e.g. dissociation, excitation, ionization, etc.) determines the density of a particular species in the plasma (e.g. ions, radicals, etc.)

Ref: https://doi.org/10.1116/6.0000145

4. The thickness of the plasma sheath is typical ~0.1 to 10mm depending on the electron density, the electron temperature, and the potential difference between the plasma and the surface in contact with the plasma (the larger the potential difference is, the thicker the sheath is). The plasma sheath bends along the surface of the macroscopic objects and ions strike every surface of the object orthogonally. However, the plasma sheath can’t follow the surface of the microscopic features (e.g. microscopic trenches in a wafer), thus the ions bombard only the top and the bottom flat surfaces of the features.

5. Plasma source can also be a big source of Oxygen contamination when gets eroded by ion bombardment. It’s especially a big problem in the PEALD of nitrides in ICP systems. In this regard, the use of Alumina as a dielectric window in an ICP system can lead to less sputter yield than that from the use of Quartz as a dielectric window, thereby providing better quality nitride films. This is the reason why many companies have adopted Hollow Cathode Plasma source developed by Meaglow Ltd. in their systems.

6. Vacuum systems themselves can also be a source of Oxygen contamination, especially the ALD reactors because they typically don’t have very low base pressure; usually ~10-6 Torr after utilizing a turbo molecular pump. If the ALD cycle times are relatively long such that the reactive surfaces are exposed to the (“poor”) vacuum for a relatively long time, the Oxygen concentration in the deposited film increases. In other words, the faster the ALD process is, the less contaminated the deposited film is.


An example was given from ALD of HfN from Research of Saurabh Karwal from TU Eindhoven (To be published in 2021) studying the impact of oxygen incorporation by artificially extended cycle times.


7. Strong pumping does not only lead to a better vacuum and in turn less Oxygen contamination in the deposited film, but it also helps reduce the gas residence time inside the reactor minimizing the surface reaction by-products being cracked in the plasma and redepositing on the surface. Thus, a higher pumping speed results in a higher quality film growth.

8. Regarding the conformal growth of an ALD film: When S0*AR2 < 0.1, the film growth is reaction-limited, and extending the precursor/co-reactant dose (beyond the saturation dose) will not make any difference in the film conformality. It’s similar to the growth on a planar substrate. However, when S0*AR2 > 100, the film growth is diffusion-limited, and hence, the precursor/co-reactant dose, that needs to be applied to get a fully conformal growth in the trench, scales with the AR2. In the case of PEALD, the film growth can be recombination limited too, and it becomes even difficult to get a conformal film growth because of the co-reactant dose that needs to be applied to get a fully conformal growth in the trench scales exponentially with the AR. The conformality becomes further difficult to achieve when the surface recombination probability r of the radicals strengthens. Moreover, the conformality of the PEALD film depends heavily on the film material to be deposited because the surface recombination probability of the radicals heavily depends on the material, e.g., SiO2 films can go much deeper into the trench than Al2O3 or HfO2 films since the surface recombination probability of O radicals on SiO2 is much lower than that on Al2O3 or HfO2. The surface recombination probability also depends on the substrate temperature and the process pressure.

[S0 = Sticking probability with zero surface coverage, AR = Aspect Ratio of the trench]

9. PEALD film properties are strongly dependent on ion-energy dose = plasma exposure time*ion flux*mean ion energy. By applying substrate biasing, i.e., by employing mild ion bombardment, mass density, refractive index, crystalline properties, resistivity, void fraction, residual stress, surface roughness, thickness uniformity, chemical composition, topographic selectivity, etc. of the deposited film can be tuned.

10. Plasma can cause radiation damage in the PEALD films because plasma also comprises radiation in the vacuum ultraviolet (VUV) region (i.e. wavelengths below 200nm) generating VUV photons that can have energy up to even 10-40 eV. However, this certainly can’t disqualify plasma processing in the semiconductor industry because there are methods to avoid the adverse impact of VUV photons, e.g., working at higher process pressure as the VUV photons are easily absorbed by the gas.

11. Some of the applications of PEALD in the Logic HVM include cut mask gap-fill, single diffusion break (SDB) gap-fill, contact over active gate (COAG) self-aligned contact (SAC) gap-fill, gate oxide for the IO transistors, solid-state doping, patterning hard-mask, etc. and in the Memory HVM include raising contact pad landing by depositing SiN, slide oxide line, GST X-point (phase-change) memory inner liner, etc. Topographically selective PEALD has been in use in 3D NAND production. The biggest PEALD market at present is that of self-aligned multiple patterning with SiO2 since 22 nm node. It’s important here to note that more than 50% of the PEALD layers are sacrificial and don’t show up in the device! PEALD of SiO2 has also been in the display market, e.g., in a barrier stack against moisture permeation in the curved plastic OLED displays in the Cadillac Escalade 2021. In addition to that, PEALD SiO2 has also found its application in the nanoscale encapsulation of perovskite nanocrystal luminescent films to enhance its stability against water, light, and heat.

  • Gartner expects WFE to increase by 23% in 2021 (April 2021), up from +8% still predicted in December 2020
  • VLSI Research expects WFE to increase by 22% in 2021 (April ’21), up from a previous forecast of +12% last February

“2021 started very strong for ASM,” said Benjamin Loh, President and Chief Executive Officer of ASM International. “In the first quarter, we realized revenue of €394 million, well within our guidance of €380-400 million and up 14% from the level in Q4. The revenue level was again driven by continuous high demand in the logic/foundry segment. Our Q1 order intake, at €411 million, was up 8% from an already high level in Q4 and ahead of our guidance of €380-400 million, driven by solid demand in logic/foundry. Our gross margin was at a high level of 49.5%, caused by a favorable mix, while our operational cash flow showed a record high level in Q1. Based upon the strong cash position at the end of March, we plan to start a new €100 million share buyback program.”

Outlook

For Q2, on a currency comparable level, we expect revenue of €390-€410 million. Q2 bookings, on a currency comparable level, are expected to be in the range of €420-€440 million.

“Based upon the current market developments, the wafer fab equipment (WFE) market is expected to grow by a high-teens to low twenties percentage in 2021.”

Based upon the current market developments, the wafer fab equipment (WFE) market is expected to grow by a high-teens to low twenties percentage in 2021. 2021 is expected to develop in another year of solid growth for ASM. Based upon our current view, we expect our sales in the second half to be at least at the same level as in the first half.

ALD and New Market segment

"Moving to the longer-term outlook, ALD continues to be an important, long-term growth market for ASM. For 2020, we estimate the single wafer ALD market, to reach the size of US$1.5 billion in line with the expectations we put out several years ago. We are currently reviewing our focus and expect to present the new market for customers later in the year. However, it is clear to us that ALD will remain the fastest-growing segment of the deposition market, with substantial, double-digit growth potential in the coming years. ALD is a critical technology for our industry to develop the next generation's faster processes and memory devices that in turn will enable the growth of key markets such as in 5G and artificial intelligence." - Benjamin Loh

DRAM and High-k/Metal Gate adaption with ALD

ASM's recent most significant achievement in expanding our memory presence has been in ALD wins for high-k metal gate in the high-performance DRAM segment, with the leading memory players. It is a key technology that reduces device leakage and thereby supports increases in both energy efficiency and device performance. As reported earlier, ASM books their first meaningful sales for this application last year and expects it to support a healthy increase in our DRAM sales this year.

What has been launched today is primarily what is called the high-performance DRAM segment or sub-segment within the DRAM market and it has been adopted by all the DRAM manufacturers.

ASM ALD Market Share

According to the information given in the call, Gartner report ASM´s market share in the single wafer ALD market has grown from 57% to 60% during 2020 and Benjamin Loh agreed that that estimate is in the right direction.

Spatial atomic layer depos­ition system FHR.Star.400x300-SALD delivered

FHR (Press Release) has suc­cess­fully delivered the FHR.Star.400x300-SALD. This is FHR’s first machine using spa­tial atomic layer depos­ition (spa­tial ALD). The sys­tem is cap­able of depos­it­ing films on both 200 mm wafers and tex­tiles or other 3D sub­strates of up to 400 x 300 x 10 mm³.


Spa­tial ALD allows for high speed and highly con­formal coat­ings on flat as well as micro-struc­tured sur­faces. Applic­a­tions are dielec­tric lay­ers for anti-reflect­ive coat­ings on lenses as well as coat­ings for elec­trical insu­la­tion or pro­tec­tion against mois­ture or oxy­gen applied to energy sys­tems, med­ical devices or func­tion­al­ized tex­tiles.


In its base con­fig­ur­a­tion, the FHR.Star.400x300-SALD is made for thermal ALD on up to eight wafers or four 3D sub­strates in par­al­lel. For Al2O3 on wafers, depos­ition rates of 5-10 nm/​min and thick­ness non-uni­form­it­ies <± 2.0% have been reached. A large blind flange allows to add other thin film tech­no­lo­gies or plasma treat­ment and the machine is already pre­pared to for in-situ ellip­so­metry and trans­mis­sion spec­tro­scopy for improved pro­cess con­trol. To fur­ther increase the pro­ductiv­ity, the FHR.Star.400x300-SALD can be included in a cluster setup with a cent­ral hand­ling robot cham­ber, load locks, pre-treat­ment cham­bers or other pro­cess cham­bers.


FHR, Marian Böh­ling (CSO): „ALD coat­ing tech­no­logy is val­ued for its unique con­form­al­ity and pre­ci­sion even on 3D sub­strates but claimed to be slow and there­fore often ignored. Our FHR.Star.400x300-SALD refutes this claim impress­ively and makes ALD avail­able as an excit­ing and prom­ising thin film tech­no­logy for a wide range of indus­trial applic­a­tions. Installed at a world-class thin film research insti­tute, this FHR.Star.400x300-SALD offers a low-threshold access for every­body inter­ested in using ALD for own products.“

FHR Anla­gen­bau GmbH - The Thin Film Com­pany was foun­ded in 1991 and offers tailor-made vacuum coat­ing sys­tems and sput­ter­ing tar­gets as well as coat­ing and equip­ment ser­vice from a single source.

The close cooper­a­tion with our cus­tom­ers starts with the pro­cess devel­op­ment and con­tin­ues with the devel­op­ment of pilot scale up to mass pro­duc­tion. Our port­fo­lio integ­rates the tech­no­lo­gies sput­ter­ing, evap­or­a­tion, PECVD and ALD into the equip­ment types cluster, inline, roll-to-roll and batch. Based in Ger­many and with sys­tems installed world­wide in vari­ous indus­tries such as semi­con­duct­ors, MEMS, elec­tron­ics, sensor tech­no­logy, optics, photo­vol­ta­ics, etc., we will jointly find vacuum coat­ing solu­tion for our cus­tom­ers.

Unraveling the different causes behind ferroelectricity in HfO2

Interplay between oxygen defects and dopants: effect on structure and performance of HfO2-based ferroelectrics

Monica Materano et al
Inorg. Chem. Front., 2021, Advance Article https://doi.org/10.1039/D1QI00167A

Abstract: Ten years after the first report on ferroelectricity in HfO2, researchers are still occupied unraveling the different causes behind this phenomenon. Among them, oxygen related defects seem to play a major role, affecting both crystalline phase formation and performance of HfO2-based devices. This review surveys the available literature and provides a broad picture on the topic, starting with an overview of existing oxygen-related defects, assessing the extensive calculations and experimental reports on phase stabilization in both undoped and doped HfO2 and concluding with a discussion of device reliability involving oxygen vacancies, first in more classical HfO2 applications such as MOSFET high-k metal gate and resistive switching devices and later in the three major groups of ferroelectric non-volatile memory devices.

ALD coating for delayed drug delivery via the lungs for the treatment of respiratory diseases by Astra Zeneca and TU Delft

The medical thin film coating segment is a mature and growing market for CVD & PVD coating equipment and ALD is an emerging segment. Applications are :
  • electronic implants (IC, BioMEMS, Pacemaker) 
  • prosthetic implants (spine, trauma, hip, knee, dental)
  • active pharmaceuticals ingredients for  delayed drug delivery

ALD has slowly but steadily moved into the field of medical and pharmaceuticals. Just as some examples Nanxa AB in Sweden and Applied Materials has a joint venture and Picosun in Finland and Veeco has very active business unit and offer ALD systems specifically for medical applications for several years. As well as several reports on applications such as dental, tissue engineering, smart lenses, and various electronic or prosthetic implants.

Here is a new application explored by Dutch TU Delft and British-Swedish Astra Zeneca using ALD coating for delayed drug delivery via the lungs for the treatment of respiratory diseases.

Controlled Pulmonary Delivery of Carrier-Free Budesonide Dry Powder by Atomic Layer Deposition
ACS Nano 2021, XXXX, XXX, XXX-XXX
Publication Date:March 26, 2021, https://doi.org/10.1021/acsnano.0c10040



Ideal controlled pulmonary drug delivery systems provide sustained release by retarding lung clearance mechanisms and efficient lung deposition to maintain therapeutic concentrations over prolonged time. Here, we use atomic layer deposition (ALD) to simultaneously tailor the release and aerosolization properties of inhaled drug particles without the need for lactose carrier. In particular, we deposit uniform nanoscale oxide ceramic films, such as Al2O3, TiO2, and SiO2, on micronized budesonide particles, a common active pharmaceutical ingredient for the treatment of respiratory diseases. In vitro dissolution and ex vivo isolated perfused rat lung tests demonstrate dramatically slowed release with increasing nanofilm thickness, regardless of the nature of the material. Ex situ transmission electron microscopy at various stages during dissolution unravels mostly intact nanofilms, suggesting that the release mechanism mainly involves the transport of dissolution media through the ALD films. Furthermore, in vitro aerosolization testing by fast screening impactor shows a ∼2-fold increase in fine particle fraction (FPF) for each ALD-coated budesonide formulation after 10 ALD process cycles, also applying very low patient inspiratory pressures. The higher FPFs after the ALD process are attributed to the reduction in the interparticle force arising from the ceramic surfaces, as evidenced by atomic force microscopy measurements. Finally, cell viability, cytokine release, and tissue morphology analyses verify a safe and efficacious use of ALD-coated budesonide particles at the cellular level. Therefore, surface nanoengineering by ALD is highly promising in providing the next generation of inhaled formulations with tailored characteristics of drug release and lung deposition, thereby enhancing controlled pulmonary delivery opportunities.

Picosun increases efficiency for LED and OLED production

ESPOO, Finland, 13th of April 2021 – Picosun Group has proved to significantly increase the production efficiency of its LED and OLED customers with the PICOSUN® P-300BV ALD system. Recent tests show that a reduced ALD process cycle time and an increased number of wafers deposited with the same film thickness resulted in almost 100% better throughput. A throughput of over 20 000 wafers per month can be reached with a wafer batch of 100 wafers*. At the same time, the process quality in terms of film thickness uniformity has remained on an excellent level (<1% 1sigma) when measured within wafer, wafer to wafer as well as batch to batch.



“Picosun ALD solutions have become the standard in high volume ALD manufacturing. PICOSUN® P-300BV ALD system is designed especially for production of LEDs and OLEDs. With our experience and deep know-how in ALD we are continuously striving to minimize the total cost of ownership and ensure future-proofness for our customers”, states Juhana Kostamo, Vice President, Industrial Business Area of Picosun Group.

Global LED and OLED manufacturers trust in ALD in their production to achieve better device performance and longer product lifetimes. This is a result of thin, conformal, uniform and pinhole-free material layers deposited by ALD for passivation and moisture protection as well as for creating buffer and interface layers.

Spatial Atomic Layer Deposition (SALD): Essential for today's and future battery production

SALD is a carve-out of the brainport Eindhoven-based OEM company SoLayTec, which develops and sells advanced spatial ALD machines specifically for mass-produced solar cells. Because there were a lot of requests for applications other than solar cells, the company SALD was founded in 2019. In the relatively short time in which the company has existed, it has already succeeded in implementing the complex technology in a compact machine that serves for research purposes and small-scale production of spatial ALD layers.

The full story can be found here published by Brainport, NL: LINK


Background: In 2008 TNO scientists developed a brilliant solution for this: Spatial ALD. With this new technology, TNO was able to increase the production speed 5 to 10 times, while the coating quality remained the same. This led to the establishment of SoLayTec, which developed and sold advanced Spatial ALD machines for the mass production of solar panels. This makes SoLayTec the only company with large-scale production experience within the emerging world of Spatial ALD. The in-depth expertise in Spatial ALD technology, combined with the unique ability to transfer it from lab to fab, offers great opportunities in today's growth markets. That is why a new company has been set up alongside SoLayTec, with the ambition to be at the forefront of promising new applications of Spatial ALD. The name chosen is the worldwide abbreviation for this innovative technology: SALD.

Why China denied Applied Materials take over of Hitachi Kokusai

According to a recent analysis by Robert Castellano (Seeking Alpha/The Information Network LINK), Hitachi Kokusai holds a strong position in tube/non-tube LPCVD and oxidation/diffusion semiconductor equipment. For some time Applied Material has planned the acquisition of Kokusai that would have increased its global market share, for silicon wafer processing equipment by adding a big segment that it does not have in its product portfolio - LPCVD, Diffusion, and ALD Furnaces. According to the market assessment, Hitachi Kokusai holds a leading market share in this segment over No. 2. Tokyo Electron. 

Castellano brings up the interesting observation that "China blocked Applied Materials' acquisition of Kokusai while permitting the Marvell-Inphi deal the same week". Basically meaning that there are more than just US-China Trade issues behind the decision. He concludes that "China is developing a home-grown equipment industry infrastructure, and the deal would impede on that effort." and follows up by breaking up the segments and global competitive situation as below.

Summary by Castellano of China OEM active in LPCVD, Diffusion, and ALD segments vs. the global leaders

China’s NAURA makes oxidation and diffusion furnaces and its products have captured a significant share (40-50%) of YMTC’s thermal process equipment purchases, per our channel checks. In RTP, major players include Applied Materials, Tokyo Electron, and Mattson Technology.

NAURA is developing etchers and deposition equipment for 7nm and 5nm nodes. NAURA has a large product offering, and its customers consist of SMIC, Hua Hong, YMTC, and GTA Semiconductors.

NAURA also makes thermal furnaces and has a 45% share of China’s memory maker YMTC purchases. Whereas NAURA sold 8 etch systems and 6 CVD and ALD deposition systems to Chinese semiconductor companies, the company sold 34 furnaces in 2019 as well as 16 cleaning systems.

Shenyang Piotech also supplies PECVD and ALD deposition equipment. Piotech received orders for 4 PECVD (for SiN, SiO2) systems from YMTC, and is also receiving repeat orders from Hua Hong, and SMIC.
