Meaglows New Hollow Cathode Plasma Source Designs Provide Better Quality Films

The University of Connecticut group of Dr. Necmi Biyikli, with others, have recently published a paper (J. Vac. Sci. and Technol. A 37 (2019) 020927) where they were able to achieve good quality, highly stoichiometric AlN using hollow cathode plasma-assisted atomic layer deposition (HCPA-ALD) with film densities near bulk values. Because of the high radical flux from the source, significantly lower RF power was required to achieve this improvement in material quality compared to past experience, and shorter plasma on cycles could be used at these lower powers (20 seconds at 100 watts compared to 40 seconds at 300 watts).

Similar improvements in silicon nitride deposition were recently achieved by a team at the University of Texas, Dallas, where excellent quality, highly stoichiometric, high-density PA-ALD grown material was performed using one of our hollow cathode plasma sources (see, for instance, IEEE Electron Device Letters 39 (2018) 1195 ).

The image shows the University of Connecticut plasma source with ellipsometer ports and sample entry door. The 4″ diameter source was custom made for use with an Okyay Tech ALD system.

Meaglow’s hollow cathode plasma sources are widely used by the ALD Research Community as replacements for inductively coupled plasma (ICP) sources because there is less oxygen contamination when depositing non-oxide materials. However, these recent papers, by the University of Connecticut and the University of Texas, Dallas, illustrate advantages that may be far more important for the industry moving forward. Those being an extremely high radical flux, to the point where the ion signal (ion densities are similar to ICP sources) is swamped by the signal of radicals during optical emission spectroscopy measurements, and relatively low plasma damage (see our company white paper on hollow cathode sources). These result in quicker deposition times with potentially more stoichiometric, better quality material.

Amtech Systems plans to divest its solar businesses

Amtech Systems, a manufacturer of capital equipment and consumables used in fabricating semiconductor devices, LEDs, SiC and silicon power chips ans well as solar cells, is planning to sell its solar businesses.

Amtech management and Board of Directors have decided to focus solely on growth opportunities in the Company’s semiconductor and SiC/LED polishing businesses and intend to sell the Company’s solar businesses, including its Tempress and SoLayTec subsidiaries. 

Amtech’s J.S. Whang, Chairman and Chief Executive Officer, commented, “In November 2018 we announced that we had initiated a comprehensive review of our solar businesses.  In a February update we noted thus far our review strongly indicates that our combined Semi and SiC/LED polishing business provide better markets for enhancing the value of Amtech Group. We have recently completed our assessment and conclude, along with Tempress and SoLayTec management, that significant investment is required to effectively compete in the changing solar industry. We therefore conclude Tempress and SoLayTec would be better positioned to capitalize on opportunities in the solar industry under new ownership.”

RASIRC to Highlight Precise Water Vapor Delivery in Area Selective Deposition

CTO featured as industry expert on panel at upcoming ASD Workshop

San Diego, Calif – March 29, 2019 – RASIRC will discuss test results for precise delivery of water vapor at the Area Selective Deposition (ASD) 2019 Workshop on April 4-5 in Leuven, Belgium. The company, a Silver Sponsor of the workshop, will review droplet and particle measurements as well as mass delivery under a variety of conditions. The RASIRC poster entitled “Precise Control of Water Vapor Delivery for ASD” will be displayed on Thursday April 4 and Friday April 5 as part of the workshop’s poster session. Additionally, RASIRC CTO Daniel Alvarez will be a speaking on the “Critical Challenges and Research Needs for ASD” panel during the 4th ASD workshop. The panel discussion will take place on Friday April 5 from 15:00 to 16:00.

“In order for the industry to take this to a high volume commercial level, we first must have an understanding of the underlying chemical pathways associated with ASD,” says Alvarez. “It is critical to control nucleation, which is best accomplished by the control of adsorption and surface properties on an atomic level.”

 

 

ASD Workshop is an annual event sponsored by ASM and IMEC. The workshop features leading academic and industry experts in surface chemistry, new processes, metrology, fields of applications and all technology needs and challenges for ASD.

“Controlled water addition at low concentration and temperature is vital to successful selectivity in ASD processes,” said Jeffrey Spiegelman, RASIRC President and Founder. “That is why we designed a water ampoule replacement that utilizes a membrane delivery system for precise delivery of droplet-free water vapor. Our data shows that we can achieve the required mass output in a repeatable and consistent manner.”

Spiegelman and Alvarez will be available to discuss the company’s ASD product line-up, which includes hydrogen peroxide and hydrazine gas delivery in addition to water vapor.

About RASIRC Products

RASIRC RHA enables the delivery of purified water vapor into low pressure processes. The membrane delivery system separates the liquid water and its headspace from directly seeing the process vacuum. The membrane assembly allows the mass transfer of water vapor at a known diffusion rate for a given set of parameters (temperature, pressure, surface area, carrier gas flow rate).

BRUTE® Peroxide is a novel oxidant that improves nucleation density at film interfaces when compared to other oxidants. Surface functionalization is more dense and initiation is faster using anhydrous hydrogen peroxide gas compared with alternatives. This can allow for better selectivity and less damage to metal surfaces in ASD processes.

BRUTE® Hydrazine enables uniform nitride deposition for Silicon and early transition metals at low temperature. BRUTE® Hydrazine may also be used as an atomic hydrogen source, where metals such as Ru, Cu, and Co may be cleaned and reduced. Hydrazine gas is generated in situ and is virtually water free. Brute Hydrazine has been formulated for a relatively high flash point for safer handling.

RASIRC 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.

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

Integration of high-k dielectric materials in a-IGZO thin film transistors by ALD

High field-effect mobility of Amorphous Oxide Semiconductor Thin Film Transistors (AOS TFT’s) has become more critical in switching devices for active matrix OLED’s (AMOLED). 

Out of many AOS materials, stable a-IGZO (Indium Gallium Zinc Oxide) TFT’s has shown high performance in display devices. However, the process integration of TFT’s is very complicated where a high number of parameters are to be considered and optimized to obtain maximum device performance. Therefore, it is essential to develop each process step through various device structure of thin film transistors using Back Channel Etch and self-aligned TFT. 

An example: Magnified image of the AMOLED screen on the Google Nexus One smartphone using the RGBG system of the PenTile matrix family (Wikipedia).

Currently, incorporation of high–k dielectric materials such as Al2O3 and HfO2 as a passivation layer and gate insulating material shows promising results in obtaining high performance of TFT’s in terms of low operating voltages, bias stability and reducing degradation by isolation from the external environment. A primary focus is on Al2O3 films by ALD technique, where the doping of film to the active layer (a-IGZO) is investigated through back channel etch (BCE) device structure by two different deposition temperatures followed by annealing studies. The performance of the self-aligned TFT's is primarily determined by the two factors :

I. Deposition temperatures of the passivation layer (Al2O3) 

II. Etching rate. 

The conclusions drawn from the studies of BCE applied to a-IGZO 10% O2 aelf–aligned (SA) device structures where Al2O3 layer deposited by ALD at 150 °C as a gate insulating material. The electrical characteristics of fabricated Thin Film Transistors are obtained to be very promising for further engineering applications. 

A deep study and understanding of each step in process flow and significance of Atomic Layer Deposition gave a fruitful insight into many aspects.
