Measuring Hydrogen, Carbon, Oxygen and Iron Contamination in ALD Films

Contamination in ALD for Semiconductors

Atomic layer deposition (ALD) is a useful technique that can produce films that contain high levels of hydrogen, carbon, oxygen and other metals, which are not desirable elements for semiconductor films. To detect any contamination of these elements in semiconductor films, a number of improve plasma sources in nitride-based ALD grown films can be used. Additionally, X-ray photoelectron spectroscopy (XPS) can also be used to detect accurate composition profiles, however for hydrogen, carbon and oxygen concentrations of 5% or less can become background limited. In cases where the hydrogen, carbon and oxygen profiles are 5% or lower, SIMS analysis is often required.

RASIRC Turns Thermal Mass Flow Measurement of Dilute Reactive Gas Species Inside Out

Company features new thermal mass gas sensor at ALD for Industry 2018

San Diego, Calif – March 19, 2018–RASIRC will present an new thermal mass gas sensor for independent measurement of precursor flow rate at the ALD for Industry 2018 conference held in Dresden, Germany March 21 and 22. The presentation will discuss the importance of precursor gas flow measurement independent of carrier gas flow and will provide experimental performance data with hydrogen peroxide gas. The company will also discuss its metal nitride and metal oxide precursor gases in the exhibits area. 

Jeff Spiegelman at ALD for Industry last year (EFDS ALD for Industry 2017, 17-18 January Dresden, Germany)
RASIRC is a conference sponsor and will also participate in the exhibition. ALD for Industry is sponsored by the European Society for Thin Films (EFDS) and is a topical workshop focused on industrialization and commercialization of ALD for current and emerging markets.

“Process control is crucial for product yields and materials utilization,” said Jeffrey Spiegelman, RASIRC President and Founder. “New RASIRC monitoring technology solves a difficult problem for highly reactive gases, enabling better process stability and lower materials cost.”

RASIRC Brute Peroxide is a novel oxidant that improves passivation and nucleation density at film interfaces when compared to other oxidants. Surface functionalization is denser and initiation is faster using this anhydrous hydrogen peroxide gas compared with alternatives. This high reactivity allows for less chemistry use, and higher throughput due to shorter required purge times.

BRUTE Hydrazine enables low temperature ALD (sub-350°C) . Highly reactive, BRUTE Hydrazine creates uniform metal nitride deposition on 3D surfaces for barrier layers and atmospheric protection.

RASIRC’s Peroxidizer® provides high volumes of reactive H2O2/H2O mixtures for high throughput ALD. This reactive gas generator is ideal for roll-to-roll ALD coatings that require high speed deposition at reduced temperatures.

RASIRC products also include the RainMaker Humidification System (RHS) that generates water vapor for oxidation applications, and the Hydrogen Peroxide Steamer (HPS) for surface cleaning, preconditioning, wet thermal oxidation and residual carbon removal.


RASIRC specializes in products that generate and deliver gas to fabrication processes. Each unit is a dynamic gas plant in a box—converting common liquid chemistries into safe and reliable gas flow for most processes. First to generate ultra-high purity (UHP) steam from de-ionized water, RASIRC technology can now also deliver hydrogen peroxide gas and hydrazine gas in controlled, repeatable concentrations. RASIRC gas delivery systems, humidifiers, and closed loop humidification systems are critical for many applications in semiconductor, photovoltaic, pharmaceutical, medical, biological, fuel cell, and power industries.

Amazing rock n roll ALD machine from Boulder Colorado

Those of you that follow ALD knows that much of the new cool and exciting ALD processes, precursors and technology comes out of Boulder Colorado and especially the Prof. Geroge Group. Some personal favourites and examples are:

- Tungsten ALD
- Low temperature SiO2 catalytic ALD [LINK]
- Implementation of QCM in ALD as a standard tool
- Reverse ALD with new chemistries a.k.a. thermal ALE
- ALD on particles

Obviously many other labs also work hard on these new approaches but somehow the Gerorge Lab always produce that fundamental benchmarking type or research that you tend to return to long after it was published. The best thing is that all the publications are listed and partially available in the long list of publications (LINK) so it is easy to come back later and find the publications.

Just the other day this amazing video of a rock n roll ALD machine from Boulder Colorado was posted on LinkedIn (LINK) by Alexander Yersak, who is a post doc there. Turn on the volume and have a look yourself!

Picosun announces significant repeat sales of P-300F batch ALD cluster tools

ESPOO, Finland, 19th March, 2018 – Picosun Group, a leading provider of Atomic Layer Deposition (ALD) thin film coating technology for global industries, reports of significant repeat sales of PICOSUN™ P-300F production cluster tools to major US industry customers.

Semiconductor components manufactured on silicon and compound semiconductor wafers are crucial in several everyday consumer electronics products as well as in e.g. transport, aerospace, or industrial automation and power applications. Even if the majority of the most common IC components is produced on 300 mm silicon wafers, the sub-300-mm manufacturing is vital and increasingly important especially for the existing and emerging non-silicon-based devices. Wafer materials limited to max. 200 mm diameter such as SiC, GaN, AlN, sapphire, GaAs, LiNbO3, and LiTaO3 offer various benefits over silicon and enable a generation of completely new, advanced and innovative end products.
The PICOSUN™ P-300F ALD system is specially designed for production of IC components such as microprocessors, memories, and hard drives, and manufacturing of power electronics, mixed signal, and MEMS devices such as print heads, sensors, and microphones (LINK).

Picosun’s core competence are cost-efficient, turn-key ALD production solutions for the fast growing More-than-Moore market. The PICOSUN™ P-300F tool is the flagship product for these customers. Specially designed to be run in cluster configuration under constant vacuum to enable fast and efficient high throughput manufacturing, the P-300F tools are connected together and operated in fully automatic mode with a central vacuum robot substrate handling and transfer system. The unique batch flipping mechanism in the P-300F tool is ideal for manufacturing lines where the most of the process steps take place in horizontal geometry. Cassette-to-cassette loading for up to 50 pcs batches of 200/150/100 mm wafers, SEMI S2/S8 certification, and SECS/GEM option for factory host integration make the P-300F the optimal choice for demanding manufacturing needs for e.g. moisture barriers, capacitors, and SAW/BAW filters.

“We at Picosun are very happy of the success of our P-300F cluster tools. Our customers have obtained unparalleled process results in them, and this excellent performance has now resulted in repeat sales of these tools to our key industrial customers. The purity, uniformity, and barrier properties of the ALD films deposited in these systems fulfil the strictest requirements of today’s semiconductor industries, making the PICOSUN™ P-300F the tool of choice for the forerunners of semiconductor manufacturing,” states Juhana Kostamo, Managing Director of Picosun.

MKS has won significant business from a Korean end-user for ALD high flow of ozone systems

Since basically the start of ALD in high volume DRAM manufacturing on 300 mm wafers, ozone has been employed as the co-reactant for ALD of hafnia and zirconia based high-k node dielectrics in the DRAM capacitor memory cell. The ozone concentration directly controls through-put, uniformity and conformalty of the deposited high-k and most importantly also the high-k dielectric performance of the layer including CET/Leakage performance and log term reliability. Please see this early post on details for these processes (LINK)

Just recently MKS Instruments reported (Seeking Alpha Earnings call transcript, LINK) that they won significant business from a Korean end-user for a high flow of ozone systems used in atomic layer deposition to fabricate DRAM memory devices. In addition, MKS reported to have just received a significant suppler award from another major Korean OEM.

MKS further stated that they have made strategic investments with a significant impact on their semiconductor OEM and end-user businesses. Amazingly, the revenue in Korea has increased 250% since 2012. In 2017 alone, their Korea end-user business grew 114%, while the Korea OEM business grew 96%.

Based on this we may assume that high concentration ozone supply i still crucial for the ALD oxide processes in DRAM manufacturing.

RMD Dynasil employ CdTe ALD process for passivating HgCdTe IR sensors

Dynasil’s Radiation Monitoring Devices (RMD) is a world-renowned expert in the scintillation, photodetection, and radiation detection industries. At the recent Dynasil Corporation of America Annual Stockholder Meeting and Investor Presentation Conference Call it was reveiled that they have commericiallized an ALD process for passivating HgCdTe sensors with semiconductor-grade CdTe layer. The ALD coating is conformal, continuous and pinhole-free. Such low temperature CdTe ALD films have been previously published by Bengi Hanyaloglu et al (LINK).

Applications for these sensors are for:
  • Space IR telescopes
  • Tactical night vision googles and binoculars etc.
Peter Sulick - Chairman, President & CEO has this to say about the application (Seeking Alpha call transcript LINK)

"Another exciting area for research that is going on at RMD is its activation of the mercaptal infrared arrays, third-generation infrared arrays, and as people in the optic suite are well aware, this mercaptal infrared arrays require stabilization on the surfaces because of the semiconductor bonds being open at the surfaces. And one of the ways to do that is through activation layer of mercaptal films, and RMD has developed a proprietary technology using atomic layer deposition to deposit this mercaptal films. And the important advantage that our technology brings is that these are controllable films, which can be deposited at much lower temperatures than currently thought, and that can have a big impact in the yield and in the utility of these infrared sensors. So we are excited about where this area is going."

RMD has developed an ALD process for passivating HgCdTe sensors with semiconductor-grade CdTe layer. The ALD coating is conformal, continuous and pinhole-free. (Dynasil 2018 Annual Meeting Management Presentation LINK

Thermal ALD of aluminum metal at low temperature

Aluminum metal is important in semiconductor devices and as a metal itself in metallization and as an alloy in e.g. TiAl metal gates or TiAlN electrodes. Prof. Winter and his team at Wayne State have previously published new paths to thermal ALD of titanium, here they published their recent achievement for thermal ALD of aluminum!

Atomic Layer Deposition of Aluminum Metal Films Using a Thermally Stable Aluminum Hydride Reducing Agent

Kyle J Blakeney and Charles H. Winter
Chem. Mater., Just Accepted Manuscript

The thermal atomic layer deposition of aluminum metal films at temperatures as low as 100 °C is described using AlCl3 and a new aluminum dihydride complex that is supported by a bulky amido-amine ligand. A growth rate of about 3.5 Å/cycle was observed within a 120-160 °C ALD window and self-limiting growth was established for both precursors. Resistivities as low as 3.03 Ω·cm were obtained for the aluminum metal films. Root mean square surface roughnesses were 19-23% of the film thicknesses, as determined by atomic force microscopy. Films grown on TiN substrates were crystalline by X-ray diffraction. X-ray photoelectron spectroscopy of films grown at 100 and 140 °C showed Al (> 94 at%) with C and Cl impurities below the detection limit (< 1 and 0.5 at%, respectively). Accordingly, this process affords high purity, low resistivity aluminum metal films.

SoLayTec ships new ALD order to Asia for PERC cell manufacturing

North American Clean Energy reports (LINK): Amtech Systems, Inc. (NASDAQ: ASYS), a global supplier of production equipment and related supplies for the solar, semiconductor, and LED markets, announced its solar subsidiary, SoLayTec B.V., has shipped a next generation solar Atomic Layer Deposition (ALD) to an Asian customer. While the PV market is shifting towards high efficiency cell designs, production with high yield, A-grade cells, is getting increasingly important. 

Fokko Pentinga, CEO and President of Amtech, commented, "For this project we are delivering the equipment for the PERC line upgrade and assisting the customer with the PERC ramp-up and line integration. PV manufacturers are experiencing extreme price pressure, resulting in an increasing need for higher cell quality with narrow cell efficiency distribution. The highest line yield possible of A-grade cells is essential to ensure good margins for these advanced production lines. Al2O3 wrap-around during deposition will result in reduction of the cell efficiency by as much as 0.2%, as well as front side color variations. Our ALD equipment addresses PV manufacturers' challenges, by delivering the highest PERC cell efficiency using Al2O3,, highest A-grade cells, and stable deposition process without any wrap around. Another challenge we address for A-grade cells is scratch free manufacturing of SiNx deposition for rear-side capping and front-side ARC. Our scratch free solution using our direct-plasma PECVD equipment is gaining momentum, with shipments and order backlog totaling more than 1GW."
