ASM International report strong quarterly results driven by continued logic/foundry demand
- New orders at €303 million were 2% above the level of last quarter and 4% above the level of last year.
- Revenue for the third quarter 2020 was €315 million and decreased 8% compared to the previous quarter, half of that decrease is caused by exchange rate translation differences.
- Gross profit margin was 49.9% in Q3 2020 compared to 48.3% in the previous quarter, driven by an exceptionally strong mix. Operating result was €84 million compared to €88 million in the previous quarter, mainly due to lower sales, partly compensated by a higher margin percentage and lower costs.
- Normalized net earnings for the third quarter 2020 were lower at €61 million compared to €77 million in Q2 2020. Main reasons for the decline are the depreciation of the US dollar causing a translation result of €14 million negative as compared to the €6 million negative in Q2 and the €4 million lower result from investments.

Imec demonstrates CNT pellicle utilization on EUV scanner
LEUVEN (Belgium, LINK) October 6, 2020 — Imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, announced today promising results in extreme ultraviolet (EUV) reticle protection. Multiple CNT-based pellicles were mounted on reticles and exposed in the NXE:3300 EUV scanner at imec, demonstrating the successful fabrication and scanner handling of full-field CNT-based pellicles. The tested pellicles had a single-pass EUV transmission up to 97%. The impact on imaging was found to be low and correctable based on critical dimension (CD), dose, and transmission measurements.
A pellicle is a membrane used to protect the photomask from contamination during high-volume semiconductor manufacturing. It is mounted a few millimeters above the surface of the photomask so that if particles land on the pellicle, they will be too far out of focus to print. Developing such an EUV pellicle is very challenging, since 13.5nm light is absorbed by most materials. In addition, stringent thermal, chemical, and mechanical requirements must be achieved. Such highly transparent pellicle is critical to enable high yield and throughput in advanced semiconductor manufacturing.
Imec has leveraged partners in the semiconductor industry, materials companies and fundamental research to develop an innovative EUV pellicle design with potential to survive scanner powers beyond 600 Watts
“Imec has leveraged partners in the semiconductor industry, materials companies and fundamental research to develop an innovative EUV pellicle design with potential to survive scanner powers beyond 600 Watts,” said Emily Gallagher, principal member of technical staff at imec. “We have seen tremendous progress in carbon nanotube membrane development in the past year and, based on strong collaborations with our partners, are confident it will result in a high-performance pellicle solution in the near future.”
CNTs are one-atom-thick carbon sheets rolled into tubes. The CNTs can be single-, double- or multi-walled and can vary in diameter and in length. These engineered CNTs can be arranged in different configurations to form membranes of different densities. Since 2015, imec has been working with selected CNT suppliers (Canatu Oy and Lintec of America, Inc., Nano-Science & Technology Center) to develop membranes that meet the EUV pellicle targets for properties like transmittance, thermal durability, permeability, and strength and to enable the imaging results reported today. Future work will focus on achieving acceptable lifetimes for high volume manufacturing of these pellicles in scanners.

Picosun’s cluster ALD solutions enable next generation power electronics
“Power electronics is an important, fast growing market for Picosun. ALD has potential to solve various challenges manufacturers are facing in this field, and our solutions have enabled our customers to create significant added value in terms of device quality and throughput. At Picosun, we have developed several turn-key production ALD solutions specifically for 4-8 inch wafer markets such as power devices. Especially our cluster ALD systems, such as the PICOSUN® Morpher which we launched last year, have been extremely well received by our customers,” says Juhana Kostamo, Head of Customer Solutions/Deputy CEO of Picosun.
Interface trap density can be reduced by combining pre-cleaning methods with high permittivity, large bandgap insulators. High quality, defect-free high-k dielectric layers such as Al2O3, AlN or ZrO2 etc. are key in reducing power devices’ gate leakage current and to improve electron mobility and threshold voltage stability. A good example here are GaN-based HEMTs (high electron mobility transistors), which are important in various large scale practical applications, and which require efficient gate insulation and surface passivation to achieve optimal functionality.
ALD stands as a superior deposition method here compared to other thin film coating technologies such as PECVD, as ALD produces the most conformal, uniform, and defect-free films with accurate, digitally repeatable thickness control and sharp interfaces. With the right selection of ALD deposition equipment, even multilayer processing is possible i.e. various functional material layers and/or stacked films/nanolaminates can be manufactured in one process run.
PICOSUN® Morpher is a disruptive ALD production platform designed for up to 8 inch wafer industries such as power electronics, MEMS, sensors, LEDs, lasers, optics, and 5G components. Morpher’s operational agility makes the system adaptable to various and changing manufacturing needs, on all business verticals from corporate internal R&D to production and foundry manufacturing, where both the end products and/or customers’ requirements may change rapidly. Morpher can handle several substrate materials, batch and substrate sizes, and ALD materials with leading process quality. Multilayer deposition is possible, and cluster design allows integration of also other processing units such as pre-clean, RIE etc. for fully automated, high throughput continuous vacuum operation.
“In its versatility and transformability, Morpher is the epitome of our principle ‘Agile ALD’. Innovation, constant development and improvement of our ALD solutions to enable our customers’ success is our driving force at Picosun. This applies also to Morpher platform and we have some truly exciting additions to this product family coming in the near future,” summarizes Kostamo.

TANAKA Develops "TRuST" Precursor for CVD/ALD Processes; Using Liquid Ruthenium Precursor to Achieve World's Highest Vapor Pressures
TOKYO, Sep 30, 2020 - (ACN Newswire) - TANAKA Holdings Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Representative Director & CEO: Koichiro Tanaka) announced today that TANAKA Kikinzoku Kogyo K.K. (Head office: Chiyoda-ku, Tokyo; Representative Director & CEO: Koichiro Tanaka), which operates the TANAKA Precious Metals manufacturing business, has developed a new liquid ruthenium precursor named "TRuST" for CVD[1] and ALD[2] processes. The vapor pressure of "TRuST" is more than 100 times higher as compared to that to previous liquid ruthenium (element symbol Ru) precursors[3], which is currently the world's highest vapor pressure value at room temperature as per TANAKA's internal evaluation.
During this precursor development, TANAKA Kikinzoku Kogyo focused on
material design and synthesis research, while Professor Soo-Hyun Kim,
Ph.D., School of Materials Science and Engineering, College of
Engineering at Yeungnam University in South Korea, researched to
optimize the film formation characteristics.
Technologies
developed through this collaboration will help increase performance and
reduce energy consumption for the semiconductor devices used in
smartphones, computers, and the data centers where demand is to grow
well into the future.
Precursors are metal-organic compounds used
in chemical vapor deposition (CVD), atomic layer deposition (ALD) and
other processes to form thin metal films or metal wiring on substrates.
CVD and ALD processes enable the formation of films with superior step
coverage on various types of base substrate. These are useful methods
for forming films as semiconductors become increasingly miniaturized,
with increased structural complexity, and narrower wires with every new
generation.
TANAKA Kikinzoku Kogyo has developed a range of
precious metal precursors over the years, including ruthenium
precursors. This time, computer simulation and other techniques were
used to achieve miniaturization and optimization of the molecular
structure. This resulted in the successful development of a precious
metal compound in a liquid form, with high vapor pressure, and thermal
stability suited for film formation, all of which are important
characteristics for precursors. As a result, this compound has the
world's highest vapor pressure over 100 times higher than that of
previous liquid ruthenium precursors. The higher the vapor pressure of
precursors and the smaller their molecular structure, the higher the
possible concentration of precursor in the film formation chamber, and
the greater the adsorption density of precursor molecules on the
substrate surface. Compared to previous precursors, this achieves
excellent step coverage and improved film formation speed.
According
to research carried out at Yeungnam University, ALD film formation at
approximately 1.7 angstrom (A) per cycle is possible, which is the
world's fastest of its type using liquid ruthenium precursor. Also,
specific resistivity after film formation is approximately 13
microhm-cm, which is close to the value of bulk ruthenium metal (7.6
microhm-cm).
When bulk ruthenium is used for vapor deposition,
with a temperature as high as 3000 degrees C. However, if it is
converted into an organometallic compound of ruthenium precursor, it can
be vaporized at low temperatures (between room temperature to 200
degrees C) under vacuum. As a result, the formation of high-quality
ruthenium film with excellent step coverage at high productivity is
expected. This has been an issue in the past because it is technically
difficult to achieve all these characteristics at the same time. With
the development of "TRuST" however, it is now possible.
Samples of Shipments of "TRuST" should begin shipping samples are planned to start in October 2020.
Background and TANAKA Kikinzoku Kogyo's development of precursor for CVD/ALD processes
In
the past, the most common wiring materials used for semiconductors were
copper, tungsten and cobalt. However, as semiconductors have evolved,
there are increasing expectations for the precious metal ruthenium to
promote further miniaturization of semiconductors because of its lower
resistance and higher durability. With its superior characteristics,
ruthenium is also being considered for use in transistor gate electrodes
and DRAM capacitor electrodes.
The progress of technologies such
as IoT, AI, and 5G over recent years has led to rapidly increasing
volumes of digital data used in clouds, smartphones, and computers.
Therefore, the need for even greater miniaturization of semiconductors
is increasing to enable the creation of devices with higher performance
and lower energy consumption. As a specialized manufacturer of precious
metals, TANAKA Kikinzoku Kogyo will continue contributing to this
evolution of semiconductors through the development of high-quality
semiconductor materials.
With the support of Professor Soo-Hyun
Kim, from the College of Engineering at Yeungnam University, a
researcher from TANAKA Kikinzoku Kogyo will give a presentation of this
technology at the "International Interconnect Technology Conference
(IITC) 2020", which will be held online from October 5-8, 2020. The
title of the presentation is High-growth-rate atomic layer deposition of
high-quality Ru Using a Novel Ru metalorganic precursor.
[1]
Chemical vapor deposition (CVD): CVD is a chemical film formation
method. It is a method of forming thin metal films on the surfaces of
base materials or substrates through a chemical reaction induced and
accelerated by directing energy, in forms such as heat, plasma and
light, at gaseous vapor material fed into a reaction chamber at
pressures between atmospheric pressures to medium vacuum pressures
(100-10-1 Pa).
[2] Atomic layer deposition (ALD): Both CVD and ALD
are film formation methods that use chemical reactions inside reaction
chambers to deposit material onto substrates through the vapor phase.
The main difference between the two methods is that while CVD
continually forms atomic and molecular layers, ALD forms the layers
intermittently one layer at a time.
[3] Precursors: Precursors are compounds used as the raw material for forming thin metal films and metal wiring on substrates.

Picosun’s ALD technology boosts UVC LED performance
- In order to reach maximum light output and long operating lifetime,
LED chips require surface passivation to eliminate parasitic currents
caused by traps and defects
- ALD passivation layer could potentially replace the expensive hermetic seal package of the LEDs and thus lower the costs of the final device.
- Short-wavelength UVC radiation destroys bacteria and viruses so UVC
LED technology is particularly topical now during the still ongoing
COVID-19 pandemic.
ESPOO, Finland, 24th September 2020 – Picosun Group, the leading supplier of AGILE ALD® (Atomic Layer Deposition) thin film coating technology, reports excellent results in UVC (ultraviolet-C) LED performance, achieved with the company’s ALD solutions.
Excellent reliability and lifetime improvements of UVC LEDs have been obtained at Picosun’s customer and collaboration partner site, National Chiao Tung University (NCTU), Taiwan, using passivation and barrier films deposited with PICOSUN® ALD equipment(*). ALD passivation layer could potentially replace the expensive hermetic seal package of the LEDs and thus lower the costs of the final device.
“We have used Picosun’s ALD technology already for years with great success. Our PICOSUN® ALD equipment yields superior quality films which has helped us to achieve several breakthroughs in our LED research. Picosun has local presence in Taiwan and we appreciate the prompt response of their customer support if we ever have any issues. At the phase when R&D results are to be ramped up to industrial-level production, the scalability of Picosun’s ALD technology is a huge benefit,” comments Professor Hao-Chung Kuo from NCTU.
In order to reach maximum light output and long operating lifetime, LED chips require surface passivation to eliminate parasitic currents caused by traps and defects. Also barrier coating is typically needed as LED materials are sensitive to moisture. ALD is an ideal technique to manufacture both the passivation and barrier films – and when the LED size diminishes to micrometer dimensions, the only coating method capable of producing high enough quality films on the required minuscule scale. Ultra-thin, pinhole-free ALD films do not suppress the LED light intensity and they provide reliable protection against ambient conditions, whereas their superior conformality ensures no thickness variations between the facets of the LED chip. Thickness variations, typical side effect of other coating methods, can potentially lead to uneven distribution of film stress or thermal expansion behavior and risk physical damage of the chip.
Short-wavelength UVC radiation destroys bacteria and viruses so UVC LED technology is particularly topical now during the still ongoing COVID-19 pandemic. Small, lightweight LEDs enable versatile design of portable, compact disinfecting equipment, they consume less power than other UVC sources, they are durable, and they pose no risk of hazardous material leaks such as e.g. mercury lamps.
“We are happy of the achievements of Professor Kuo’s group at NCTU, and how Picosun’s ALD technology has helped them to achieve their goals in UVC LED development. Our long-term collaboration and networking with both the academia and prominent industries in this field gives us the perfect synergy advantage to facilitate implementation of these solutions in industrial manufacturing,” says Mr. Edwin Wu, CEO of Picosun Asia Pte. Ltd.
(*) UVC LED with 50 nm ALD Al2O3 passivation and normal LED packaging (no hermetic seal) maintained 80% of its original efficiency even after 500 hours environmental test at 85% humidity and 85 oC temperature.

Reverse Engineering by der8auer - Intel 14nm and AMD/TSMC 7nm transistors compared
Overclocking expert der8auer examined an Intel Core i7-8700K under a scanning electron microscope (SEM) a couple of years ago when that processor was one of Intel's best consumer offerings. This was an interesting exercise but in a recent YouTube video series der8auer has been leading up to a direct comparison between the current state-of-the-art Intel Core i9-10900K and the AMD Ryzen 9 3950X. The former is an Intel 14nm+++ production chip and the latter made for AMD by TSMC on its 7nm process.

Lam Research launch the advanced Striker® FE platform for 3D chip architectures like 3DAND and DRAM
- Lam has been leading gap fill for a long time and their new proprietary surface modification technique (ICEFill) to achieve highly preferential bottom-up and void-free gapfill while retaining the film quality inherent to atomic layer deposition (ALD).
- The platform is specially prevalent in 3D NAND devices, as well as prevents collapse issues in DRAM and logic devices.
- The Striker FE platform with ICEFill technology is part of the Striker ALD product family.
- Lam applied for ICEFill USPTO Trade Mark February 2020 (LINK)
FREMONT, Calif., Sept. 21, 2020 (LINK) -- Lam Research Corp. (Nasdaq: LRCX) today announced the advanced Striker® FE platform, a new processing solution for manufacturing high-aspect-ratio chip architectures. Striker FE utilizes an innovative, first of its kind ICEFill™ technology for filling extreme structures in 3D NAND, DRAM, and logic devices at emerging nodes. This system delivers the continued cost and technology scaling that is required to meet the semiconductor industry roadmap.
Keyword Cluster for Lam Research Gapfill (Patbase)
Traditional methods of gapfill for semiconductor manufacturing include legacy chemical vapor deposition, diffusion/furnace, and spin-on processes. These techniques are no longer viable for today’s 3D NAND requirements, as they are limited by the tradeoffs between quality, shrinkage, and gapfill voids. In contrast, Lam’s Striker ICEFill harnesses a proprietary surface modification technique to achieve highly preferential bottom-up and void-free gapfill while retaining the film quality inherent to atomic layer deposition (ALD). The ICEFill technology removes the existing limitations for filling high-aspect-ratio features which are especially prevalent in 3D NAND devices, as well as prevents collapse issues in DRAM and logic devices.
“Our goal is to provide customers with the most enabling ALD technology,” said Sesha Varadarajan, senior vice president and general manager of the Deposition product group at Lam Research. “This technology combines the ability to produce high quality oxide films with superior gapfill performance, in a single processing system with the productivity advantages offered by our industry leading quad station module architecture.”
The Striker FE platform with ICEFill technology is part of the Striker ALD product family. For more information about the Striker product family visit the product page.

Area-Selective ALD of TiN Using Aromatic Inhibitor Molecules for Metal/Dielectric Selectivity
Just making sure that you have not missed this important and amazing publication from Merkx et al at TU Eindhoven since I missed it for more than a month by now. Selective ALD of TiN - woah so beautiful! TiN CVD and ALD is used just about everywhere in wafer based-device fabrication:
- Metal diffusion barriers e.g. for Tungsten (NAND, DRAM, Logic)
- Metal Gates (HKMG, Workfunction tuning, etc.)
- Capacitor Electrodes (DRAM, ReRAM, FRAM)
- Hard mask in BEOL processing
- And much more
Please also check out the supporting information on how to create those test samples for the actually selectivity experiments - I just say it´s done in a very clever way (LINK) .
Area-Selective Atomic Layer Deposition of TiN Using Aromatic Inhibitor Molecules for Metal/Dielectric Selectivity Chemistry of Materials
Pub Date : 2020-08-13, DOI:10.1021/acs.chemmater.0c02370
Marc J. M. Merkx; Sander Vlaanderen; Tahsin Faraz; Marcel A. Verheijen; Wilhelmus M. M. Kessels; Adriaan J. M. Mackus
Despite the rapid increase in the number of newly developed processes, area-selective atomic layer deposition (ALD) of nitrides is largely unexplored. ALD of nitrides at low temperature is typically achieved by employing a plasma as the coreactant, which is not compatible with most approaches to area-selective ALD. In this work, a plasma-assisted ALD process for area-selective deposition of TiN was developed, which involves dosing of inhibitor molecules at the start of every ALD cycle. Aromatic molecules were identified as suitable inhibitor molecules for metal/dielectric selectivity because of their strong and selective adsorption on transition metal surfaces. A four-step (i.e., ABCD-type) ALD cycle was developed, which comprises aniline inhibitor (step A) and tetrakis(dimethylamino)titanium precursor (step B) dosing steps, followed by an Ar–H2 plasma exposure (step C), during which a substrate bias is applied in the second half of the plasma exposure (step D). This process was demonstrated to allow for ∼6 nm of selective TiN deposition on SiO2 and Al2O3 areas of a nanoscale pattern with Co and Ru non-growth areas. The TiN deposited using this ABCD-type process is of high quality in terms of resistivity (230 ± 30 μΩ cm) and impurity levels. This developed strategy for area-selective ALD of TiN can likely be extended to area-selective ALD of other nitrides.
