A modified open-air spatial atomic layer deposition (SALD) head is employed to fabricate complex oxide patterns on various substrates. The co-reactant being kept in the surrounding atmosphere, a simple injection head that consists of three concentric nozzles with only one precursor outlet has been designed. Easy and reversible modification in the diameter of the metal precursor outlet permits direct patterning with different lateral sizes. Maskless deposition of uniform and homogenous TiO2 and ZrO2 thin films is successfully demonstrated with a lateral resolution tuned from millimeters to hundred micrometers range while keeping the film thickness in the range of a few to hundreds of nanometers with a control at the nanoscale. This localized SALD approach, named LOCALD, also enables layer stacking and deposition on structured substrates.

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.

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.

Dutch SALD and German Fraunhofer to develop Spatial ALD technology for production of 1,000 km range EV battery modules

Several reports state that Dutch SALD, a subsidiary of SoLayTec, and German Fraunhofer have jointly developed a Spatial ALD (SALD) technology for producing EV batteries that aim at 1,000 km range.

 

Not too many details are available at this point, please check SALD below for further details

SALD: LINK

From SALD Webpage: Li-ion batteries are indispensable for consumer electronics and electric vehicles, and it is vital that the safety, longevity and capacity of these batteries is maximized. Spatial ALD can assist in this. For common Li-ion batteries that comprise liquid electrolytes, ALD can be used to prepare the solid-electrolyte interphase (SEI). This artificial SEI - typically about a nanometer in thickness - protects the anode or cathode active materials (CAMs) from the electrolyte, enhancing the long-term stability and safety of the Li-ion battery.

Holst Centre showcase spatial atomic layer deposition (sALD) for thin-film transistor (TFT) backplane

Researchers from Holst Centre have become the first to use spatial atomic layer deposition (sALD) to create both the semiconductor and dielectric layer in a thin-film transistor (TFT) backplane. Using a low-temperature, large-area process for the backplane, the team created a 200 ppi QVGA display demonstrator. The process allows TFTs to be produced on cheaper, transparent plastic foils, significantly reducing the cost of flexible electronics applications such as displays and image sensors. To showcase the technology, Holst Centre has produced a display demonstrator using a backplane of top-gated self-aligned TFTs on a PEN foil. The display is being presented at the International Display Workshop (IDW) in Sapporo, Japan from November 27-29.

The backplane was produced at temperatures below 200 °C, achieving mobilities of 8 cm2/Vs in transistors with channel lengths down to 1 μm. It was then combined with an OLED frontplane to create a 200 ppi QVGA display.


The demonstrator was produced using sALD equipment initially developed by Holst Centre and which is currently being commercialized by the start-up SALDtech. Spun out from Holst Centre in 2018, SALDtech offers the only sALD tools for Gen 1 (32 x 25 cm) substrate size flat-panel displays currently available. Earlier this year, it received a second round of investment to develop and build production equipment that could be integrated into the production lines of next-generation flexible OLED displays for mobile phones, tablets, TVs and more.


“We are already delivering TFT performance with sALD that is comparable with the best sputtered devices. And through additional optimization of processes and materials, there is considerable room for further improvements. At the same time, we are looking at producing all TFT layers with sALD to further simplify and reduce the cost of high-volume flexible TFT manufacturing,” says Ilias Katsouras, Senior Scientist at Holst Centre.

Many flat-panel displays today use the semiconductor indium gallium zinc oxide (IGZO) in the TFT backplane. IGZO is usually deposited via sputtering and requires a high-temperature anneal procedure to ensure performance. This high-temperature step necessitates substrates with high melting points, which are typically more expensive.

Developed by Holst Centre, large-area sALD is an atmospheric-pressure technique that allows ultra-thin layers of materials to be deposited quickly with high compositional control and excellent thickness uniformity. The technique has previously been used to produce high-quality individual layers of materials for solid-state batteries and TFT backplanes. Now, for the first time, Holst Centre has used sALD to deposit both the IGZO semiconductor layer and the aluminum dielectric-oxide dielectric layer in an integrated TFT process onto a low-cost, transparent plastic foil.

Using a single technique to produce multiple layers of material offers flexible TFT manufacturers the possibility of improving both production throughput and the interface between layers, which in turn increases device performance.

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."

Spatial atomic layer deposition for coating flexible porous Li-ion battery electrodes

Here is important step forward in fast roll to roll processing of Li-battery electrodes using fast spatial ALD from CU Boulder, Colorado. Spatial ALD (SALD) is based on separating the precursors and inert gas purges in space rather than in time and therefore the deposition rates up to a hundred times faster are achievable. SALD can be performed at ambient atmosphere and therefore is a cheaper technology due to less need of expensive vacuum technology compared to conventional low pressure ALD.

High speed and low cost of ownership opens the door to high volume manufacturing of bulk quantities of energy materials for applications including solar energy, energy storage, or smart windows. Previously ALD Nanosolutions has announced a Spatial ALD technology for conformal encapsulation of ALD on powder material like for instance Li-battery cathode powder (LINK). A good overview of Spatial ALD for energy applications is this review paper by David Muñoz-Rojas et al: "Spatial Atomic Layer Deposition (SALD), an emerging tool for energy materials.

High-Throughput, Cost-Effective Deposition via Atmospheric Pressure Spatial Atomic Layer Deposition

Here is a new paper on atmospheric Spatial ALD from Kevin Musselman and co-workers at University of Waterloo in Canada. According to information at The Waterloo Institute for Nanotechnology web: "Musselman helped pioneer the use of atmospheric pressure spatial atomic layer deposition (AP-SALD) thin films in optoelectronic devices. He used these films to address key questions in the field of energy conversion and to develop new optoelectronic devices. Musselman produced thin films of metal oxide alloys with tunable optoelectronic properties with which he probed loss mechanisms in colloidal quantum dot solar cells, ‘hybrid’ polymer-oxide solar cells and light emitting diodes, and all-oxide solar cells. These metal oxide films were also used to produce new, colour-pure “hybrid” organometal halide perovskite light-emitting diodes."

The ALD Passivation Market for Solar Cells is Evolving

Levitech Reports: Almere, the Netherlands – November 23, 2016 – The ongoing evolution from Al BSF cells to new PERC and n-type cell concepts will continue in the coming years. This production shift is made possible by the development of high volume capable Al2O3 deposition systems. The intrinsic properties of ALD are a perfect match with the requirements from cell design and technological point of view, both for PERC as well as n-type cells. Additionally, ALD systems result in a proven CoO benefit as compared to PECVD due to the increased maintenance interval and its beneficial effect on cell efficiencies.

从 Al BSF 电池到新型 PERC 和 n 型电池概念的持续演进将在未来的几年 中继续保 持下去。高產量 Al2O3 沉积系统 的发展推动了这一生产转变。从电池的设计 和 技 术 的 角 度 来 讲 ，无 论 是 PERC 还是 n 型电池，ALD 的固有属性可谓正应所需。除 此 之外，鉴于 ALD 系统可以增加维修间隔 并改善电池效率，它还能够带来 PECVD 不 具备的实际 CoO 益处。

Novel high-speed ALD outperforms current techniques for making displays

The Holst Centre in the Netherlands reports: Fast and industry-compatible, spatial atomic layer deposition (sALD) promises to revolutionize production of thin-film displays. Now researchers at Holst Centre have shown that sALD can deliver semiconductor layers with better performance than physical vapor deposition (PVD) at the same – and potentially even higher – throughputs. An easily scalable, atmospheric-pressure process, sALD could soon become the preferred method for creating large-area thin-film and flexible devices. 

 

A key step in producing next-generation ultra-high definition) displays is the creation of a highly uniform layer of an amorphous oxide semiconductor such as indium-gallium zinc oxide (IGZO). Today, this is typically done using a PVD technique known as sputter deposition. Sputtering requires expensive vacuum equipment and can also prove difficult to correctly control material composition and thickness over large areas. This results in variable transistor performance, particularly in thin film applications such as displays.

Now Holst Centre has shown that sALD offers an industry-compatible alternative which improves display performance and at the same time could cut production costs. The team has used the technique to create semiconductor layers with charge carrier mobilities (a key measure of semiconductor performance) of 30 to 45 cm2/Vs. This compares to typical mobilities around 10 cm2/Vs for sputtering. The sALD layers also exhibited low off current, switch-on voltages around 0 V and excellent bias stress stability.

"Spatial ALD offers all the performance advantages of traditional ALD – superior control of layer thickness and composition, large-scale uniformity and unparalleled conformability – but at 10-100 times the speed. So a typical 50-nm thick layer can be produced within the standard 1 minute window demanded by today's industrial processes," said Paul Poodt, Program Manager sALD at Holst Centre.

"The performance of sALD means semiconductor layers could become much thinner, enabling even higher throughputs and lower material consumption," added Gerwin Gelinck, Program Director Flexible and Large Area Transistor Electronics at Holst Centre. "In fact, its performance characteristics are preserved even when scaling down the semiconductor thickness to less than 5 nm. This can lead to novel semiconductor structures, such as super-lattices, with even higher electron mobilities."

The Holst Centre team and partners are now taking steps towards the upscaling and commercialization of these sALD processes and related equipment.

BENEQ ALD process beats PVD in speed, quality and cost of ownership

Readers of this blog has probably noticed that ALD is continuously taking market shares from PVD and is growing much faster than PVD. ALD is a disruptive technology in many ways especially in semiconductor manufacturing. Now BENEQ Spatial Plasma ALD process also beats PVD in speed, quality and cost of ownership for Anti Reflection coatings!

 

High-performance AR coatings for mass production 08.11.2016 | BENEQ Equipment :  Ever since we earlier this year announced the licensing of rotary spatial ALD technology and launched Beneq R11, our new rotary tool for plasma enhanced spatial ALD, we have received a steady flow of inquiries and questions about where we see the new equipment being the most useful. Plenty of things, we might say, but here is one prime example: fast low temperature optical coatings, such as anti-reflection (AR) coatings on polycarbonate.

The rotary spatial ALD technology and the Beneq R11 equipment solve two major challenges that have until now been associated with the use of ALD in optical coatings in high-volume manufacturing: the deposition rate and the deposition temperature. The new advanced spatial ALD technology has several advantages over traditional PVD coatings commonly used for optical coatings.

Ultra-fast ALD deposition rates with Beneq R11

Atomic layer deposition is well known for great thin film quality, but the low deposition rates of traditional ALD methods have prohibited its use in volume production. With Beneq R11, this is no longer an issue as we can reach deposition rates of over 1µm/h with common optical materials such as SiO2 and TiO2. This takes the technology from lab scale to high volume manufacturing in one giant leap. Some might even call the deposition rates revolutionary.

BENEQ: Ultimate OLED encapsulation with ultrafast spatial ALD

When the consumer electronics industry moves towards flexible solutions, encapsulation of flexible OLED displays against moisture permeation is one of the most difficult challenges. Totally conformal and pinhole-free ALD barrier films are ideal for ensuring a long lifetime for flexible OLEDs. They provide better barriers than traditional thick CVD solutions and much thinner coatings than the complex multi-layer PECVD barrier film alternatives.

But the coating quality of ALD thin films has actually never been the point of concern – the high encapsulation performance is widely accepted. The question in the consumer electronics business has been whether ALD can be productive enough. What has now changed?

The advances in low temperature plasma ALD processing and spatial ALD as a means to increase the equipment productivity have transformed ALD-based barrier coatings from a research topic to a viable encapsulation alternative in mass production. The high capacity of the latest spatial ALD solutions has brought the cost of ownership of ALD to acceptable levels also for consumer electronics applications.
