Medical technology is one of the key industries that reaps the benefits of the on-going digitalization and miniaturization of electronics. Instead of heavy surgeries and clumsy, expensive machines that require frequent hospital visits of the patients, diagnostics and treatments can be performed remotely and with minimally invasive methods utilizing various minuscule devices that can be either implanted inside the body or attached to skin. Lab-on-a-chip devices which combine microfluidics and microelectronics allow fast and cost-efficient in-situ analysis of body fluid and tissue samples. Implantable sensors can monitor blood glucose, blood pressure, intraocular and intracranial pressure, and heart functions. Parkinson’s and potentially many other brain diseases can be treated with implanted probes that provide electrical stimulation to the critical regions of the brain. In cardiology, catheter ablation, the common treatment of cardiac arrhythmias, can be made safer and more precise with the help of state-of-the-art microelectronics and sensor technology. Especially the elderly population benefits from these solutions when remote monitoring of various physiological markers allows them to live longer at home and severe conditions can be detected before they require long and costly hospital treatments.

NCD Contracted with TIANMA to supply 6G half ALD equipment for flexible OLED encapsulation

NCD recently signed a contract with TIANMA, one of Chinese leading display manufacturers, to provide 6G half ALD equipment for encapsulation of flexible OLEDs in the next six months to Wuhan TIANMA. This is a follow-up order to purchase NCD's 6G half (1500mmX925mm) ALD equipment, which is based on the superior performance evaluation of earlier installed 5.5G class ALD equipment in Shanghai TIANMA.

The performance of ALD encapsulation by the existing equipment showed excellent film uniformity as well as excellent moisture permeability and step coverage, compared to that by PECVD, and was qualified by the customer's flexible OLED products.

This proves that NCD's ALD core technology and the reliability of equipment have been recognized by its customer.
 

It is challenging to realize device reliability using current encapsulation technology deposited by PECVD for the next generation flexible OLED devices, since it requires bending, folding and rolling, ALD technology will be an essential choice for future flexible OLED products with its excellence and competitiveness.

NCD will make the Lucida GD series become the standard ALD equipment for all flexible OLED encapsulation based on these needs, and continue to grow into the world's most professional ALD Company with new challenges and developments.

The Material Discovery Funnel: A Six-Step Process for Advanced Material Development

The forward march of technology relies on continuous improvement of critical components such as semiconductors, batteries, fuel cells, and the like. In time, every component runs up against performance constraints established by fundamental physics and chemistry. Overcoming those restrictions requires the development of unique advanced materials that circumvent such limitations. Discovering and optimizing these types of new materials is difficult because the range of variables creates an enormous design space that is difficult to explore efficiently. Combinatorial deposition refers to a process of creating many advanced material candidates on a single substrate without removing that substrate from the chamber during the deposition process. The technique is not new in concept, but the remarkable advancements in deposition chamber capabilities and controls are making combinatorial deposition easier to implement. We refer to the process of developing advanced materials using combinatorial deposition as the "material discovery funnel."

Biologically inspired ALD:ed nanomembrane purges coal-fired smoke of greenhouse gases

(Nanowerk News) A biologically inspired membrane intended to cleanse carbon dioxide almost completely from the smoke of coal-fired power plants has been developed by scientists at Sandia National Laboratories and the University of New Mexico. The patented work, reported recently in Nature Communications ("Ultra-thin enzymatic liquid membrane for CO22 separation and capture"), has interested power and energy companies that would like to significantly and inexpensively reduce emissions of carbon dioxide, one of the most widespread greenhouse gases, and explore other possible uses of the invention. 

Enzymatic liquid membrane design and mechanism of CO₂ capture and separation. a The membrane is fabricated by formation of ~1-µm-deep oriented arrays of 8 nm diameter cylindrical silica [SiO₂] mesopores within the larger 50–150-nm pore channels of a 50-μm-thick porous alumina [Al₂O₃] Whatman^© Anodisc support. b Using atomic layer deposition and oxygen plasma processing (described in text and Fig. 4) the silica mesopores are engineered to be hydrophobic (trimethylsilyl (Si(CH₃)₃) surface groups) except for an 18-nm-deep region at the pore surface, which is hydrophilic (≡Si-OH surface groups). Via capillary condensation, CA enzymes and water spontaneously fill the hydrophilic mesopores to form an array of nano-stabilized CA enzymes with an effective CA concentration >10× of that achievable in solution. CA catalyzes the capture and dissolution of CO₂ as carbonic acid (HCO₃^–) moieties at the upstream surface and regeneration of CO₂ at the downstream surface (see Fig. 1c). The high concentration of CA and short diffusion path length maximizes capture efficiency and flux (Nature Communications article LINK)

Tuning PEALD film propperties by substrate biasing for planar and 3D applications

After having worked with dry etch people etching deep into silicon and advanced HKMG stack and other challenging and amazing things like longitudinal splitting of nanowires my experience is that they have a totally different level of insight to plasma processing technology than me the typical ALD guy. Substrate biasing is such a technology that we the usual suspects in ALD have limited insights to. You can almost hear how they laugh at us loud when we turn on our funky PEALD chambers and let the wafer float in an undefined potential state - it´s like taking a shower up in the international space station without any special precautions.

The TU Eindhoven Plasma Pro´s and their friends from Oxford Instruments, prove it time after time buy pushing out these great publications explaining to us who thinks plasmas are some sort of voodoo, They show us how it all really works in PEALD. Here is one of the most recent ones and next (April 19th) you may tune in to the Oxford Instruments Webinar and listen to Harm Knoops telling us how it really works (LINK).

RASIRC Presents Alternative Method for Aperture Oxidation in VCSELs

San Diego, Calif – April 11, 2018–RASIRC announced today that the company will present at VCSEL Day 2018, held April 12-13, 2018 in Ulm, Germany. Jeffrey Spiegelman, RASIRC President and Founder, will present an alternative method for aperture oxidation. The annual event provides a European forum to discuss the state of the art and latest research. “Wafer to wafer and batch to batch oxidation uniformity are difficult challenges in VCSEL manufacturing,” said Mr. Spiegelman. “The use of an additional and stronger oxidant such as hydrogen peroxide gas with or without water vapor is an attractive approach. This can provide an additional control parameter in order to optimize uniformity for higher yields.”

VCSELs are specialized laser-emitting semiconductors that are used in a wide variety of applications. VCSEL yield is directly related to the control during oxidation of aperture structure. Researchers have been challenged to identify additional methods to ensure uniformity. RASIRC has developed an innovative alternative that can provide better control of oxidation rate by adjustments in hydrogen peroxide concentration as well as lower process temperatures.

RASIRC’s Peroxidizer® and Hydrogen Peroxide Steamer (HPS) products provide high volumes of reactive H2O2/H2O mixtures for high throughput oxidation processes. These reactive gas generators are ideal for batch furnaces by providing the ability to vary concentration and flow rate, with or without the use of a carrier gas. Delivery into sub-atmospheric conditions is an additional feature.

RASIRC products also include the RainMaker Humidification System (RHS) that generates high precision water vapor for oxidation applications. This product has already proven to be useful in VCSEL manufacturing.

ALD on Porous Materials: Problems with Conventional Approaches to Catalyst and Fuel Cell Electrode Preparation

The last two years I have been conducting some ALD and CVD on powder and started to follow that literature segment. Here is a most recent paper (Open Access) with a lot of practical information for all of you hands-on ALD people to test in the lab (or the fab God forbid...).

Atomic Layer Deposition on Porous Materials: Problems with Conventional Approaches to Catalyst and Fuel Cell Electrode Preparation

Tzia Ming Onn 1, Rainer Küngas 2, Paolo Fornasiero 3, Kevin Huang 4 and Raymond J. Gorte
Inorganics 2018, 6(1), 34; doi:10.3390/inorganics6010034

Atomic layer deposition (ALD) offers exciting possibilities for controlling the structure and composition of surfaces on the atomic scale in heterogeneous catalysts and solid oxide fuel cell (SOFC) electrodes. However, while ALD procedures and equipment are well developed for applications involving flat surfaces, the conditions required for ALD in porous materials with a large surface area need to be very different. The materials (e.g., rare earths and other functional oxides) that are of interest for catalytic applications will also be different. For flat surfaces, rapid cycling, enabled by high carrier-gas flow rates, is necessary in order to rapidly grow thicker films. By contrast, ALD films in porous materials rarely need to be more than 1 nm thick. The elimination of diffusion gradients, efficient use of precursors, and ligand removal with less reactive precursors are the major factors that need to be controlled. In this review, criteria will be outlined for the successful use of ALD in porous materials. Examples of opportunities for using ALD to modify heterogeneous catalysts and SOFC electrodes will be given. View Full-Text
