New Fab Expansion at Sony Device Technology (Thailand) Co., Ltd.

Atsugi, Japan — Sony Semiconductor Solutions Corporation today announced that, starting in February 2024, it has begun the operations with several production lines at the new fab built on the premises of Sony Device Technology (Thailand) Co., Ltd. (“SDT”), a production center responsible for assembly processes of semiconductors. The opening ceremony was held today, officiated by top executives from Sony Semiconductor Solutions Group led by Terushi Shimizu, President and CEO of Sony Semiconductor Solutions and Yoshihiro Yamaguchi, President of Sony Semiconductor Manufacturing, SDT Managing Director Takeshi Matsuda. It was witnessed by guests including Japan’s Ambassador to Thailand, Mr. Masato Otaka, Mr. Wirat Tatsaringkansakul, BOI Deputy Secretary General and other VIPs. 

SDT serves as a production center for the assembly of the main product line within Sony’s Imaging & Sensing Solutions business. The new fab, dubbed “Building 4,” will be utilized for the assembly of image sensors for automotive applications and display devices as well as the mass production of laser diodes for data center application.

Going forward, SDT plans to expand production facilities at Building 4 in line with market trends, while also planning to create approximately 2,000 new jobs with this new operation, thereby contributing to local employment and expanding the semiconductor industry in Thailand.

In addition, SDT has been operating its facilities on 100% renewable energy since fiscal year 2021. In the clean room of Building 4, the air conditioning system controls cleanliness, temperature and humidity by focusing on areas of need, and recycling technology for waste heat and hot water has also been adopted. Furthermore, SDT plans to cover the roof area of Building 4 with solar panels, with operations scheduled by the end of 2024 (calendar year). By accelerating the initiatives to reduce energy consumption and adoption of renewable energy, SDT will continue to run on 100% renewable energy even after Building 4 goes into full operation.

“With the completion of Building 4, we are very pleased to be able to deliver to more customers, a product line-up whose market is expected to expand over the medium to long term,” said Takeshi Matsuda, Managing Director of Sony Device Technology (Thailand) Co., Ltd. “As an overseas manufacturing site of Sony Semiconductor Solutions Group, SDT will contribute to the sustainable evolution of Sony’s business as well as society.”

Toppan shifts image sensor production to China

From Nikkei Asia news:

Japan's Toppan shifts image sensor component production to China

TOKYO -- Japan's Toppan Holdings has moved production of components for CMOS image sensors from Japan to China, aiming to boost local production 40% as Beijing looks to bolster its supply chains for related technologies.

CMOS -- complementary metal-oxide semiconductor -- sensors convert light captured by camera lenses into electrical signals. Among CMOS components, Toppan produces on-chip color filters (OCF) that colorize captured images and microlenses that increase light-gathering power. Without OCF, CMOS can only detect differences in light level.

Toppan brought related equipment from its plant in Japan's Kumamoto prefecture to a facility in Shanghai and increased production lines from five to seven. They do not fall under U.S. export restrictions targeting China for advanced chipmaking equipment.

The Kumamoto plant will be used for research and development and its approximately 370 employees will be maintained.

The global CMOS market in 2022 was around $21.2 billion, according to French research firm Yole Intelligence. Sony Group leads with a 42% market share, followed by Samsung Electronics with 19% and U.S.-based Omnivision with 11%.

China's presence among top companies is limited to seventh-place GalaxyCore with 4% and eighth-place SmartSens with 2%. While Sony and Samsung manufacture OCF in-house, Chinese manufacturers mainly procure from outside sources.
In China, demand is increasing for CMOS related to automobiles, smartphones, surveillance cameras and other fields. Toppan will strengthen sales to local CMOS sensor manufacturers by producing near areas of demand.

Toppan's move comes as Beijing is spending more than $1.75 billion a year on subsidies to boost domestic semiconductor production, according to the South China Morning Post.
The U.S. has placed restrictions on the export of chipmaking equipment to China out of concerns the technology could be diverted for military purposes, making it difficult for the country to produce advanced chips.

Among chips in practical use, the most advanced level is currently said to be 3 nanometers. In general, the smaller the nanometer level for a logic chip, the more powerful it is.

Amid U.S. restrictions, China is focusing on CMOS, which differ from logic chips in manufacturing method and the definition of advanced products. Most CMOS can be manufactured using mature technology of 28 nm or greater, with the production equipment falling outside of the U.S. restrictions.
China's share based on production capacity of all 28-nm or greater so-called legacy chips is expected to reach 33% of the world's total in 2027, up 4 percentage points from 2023, according to Taiwan research firm TrendForce.

Beijing announced its "Made in China 2025" high-tech industry development plan in 2015, choosing semiconductors as a priority area. Two large government funds have been set up so far to help boost the domestic chip industry.

Plans for a third phase have recently emerged. Bloomberg reported this month that China was raising more than $27 billion from local governments and state-owned enterprises for a chip fund, the biggest of its kind.

Investment in mature technology other than CMOS is also increasing in China, and Japanese and U.S. manufacturing equipment makers are increasing sales in this field as well.
The value of chipmaking equipment shipments to China reached a record high of over $30 billion in 2023, up 6% from 2022 and putting the country first ahead of Taiwan and South Korea in imports, according to industry group SEMI.

STMicroelectronics and CEA LETI develop microlenses for SPADs

In a preprint titled "Metasurface-based planar microlenses for SPAD pixels", J. Vaillant et al. of STMicroelectronics and CEA LETI write:

In this paper we present two design generations of metasurface-based planar microlenses implemented on Front-Side Illumination SPAD pixels. This kind of microlens is an alternative to conventional reflow microlens. It offers more degrees of freedom in term of design, especially the capability to design off-axis microlens to gather light around the SPAD photodiode. The two generations of microlenses have been fabricated on STMicroelectronics SPAD and characterized. We validated the sensitivity improvement offered by extended metasurface-based microlens. We also confirmed the impact of lithography capability on metasurface performances, highlighting the need have access to advance deep-UV lithography.
