The new chip plant in Kumamoto, Japan, operated by Japan Advanced Semiconductor Manufacturing (JASM), a joint venture between Taiwan Semiconductor Manufacturing Co. (TSMC), Sony, and Denso, is poised for substantial capacity growth.

JASM President Yuichi Horita revealed that after commencing production in the fourth quarter of 2024, the plant’s production capacity will gradually ramp up, targeting a full capacity of 55,000 12-inch wafers per month.

Simultaneously, TSMC aims to enhance Japan’s semiconductor supply chain and ecosystem, looking to a 60% local contribution by 2030, a significant increase from the current 25%.

Yuichi Horita unveiled the latest plan for TSMC’s Kumamoto plant during his speech at the SEMICON Japan. He emphasized that TSMC’s Kumamoto plant is actively working to establish a local supply chain and ecosystem in Japan.

The current proportion of equipment and materials sourced from Japan for the Kumamoto plant is approximately 25%. The goal is to increase this to 50% by 2026 and achieve 60% by 2030. The progress in constructing production capacity, trial production, and mass production is in line with the original plan.

Yuichi Horita stated that the current workforce at the Kumamoto facility stands at 1,700 employees. Among them, around 600 are dispatched by TSMC and Sony, with the remaining being newly recruited staff.

The production capacity of the new Kumamoto plant primarily focuses on 28/22 nanometers and 16/12 nanometers. In the initial phase, the majority of the capacity is allocated to the manufacturing of Image Signal Processor (ISP) used in CMOS image sensors, as part of Sony’s outsourcing.

The remaining capacity is dedicated to automotive parts supplier Denso, where they outsource the production of automotive microcontroller unit (MCU), with Denso reportedly able to obtain approximately 10,000 wafers per month.

Reportedly, in industry analysis, although Japan’s recent performance in foundry has not matched that of Taiwan, South Korea, and China, Japan’s semiconductor equipment supply chain is already quite mature and comprehensive.

Major players in the field, such as Nikon in lithography equipment, and Hitachi High-Tech, renowned for etching equipment and critical dimension scanning electron microscopy (CD-SEM), have established dominance.

Additionally, Japanese companies specializing in chemical solutions, gases, and materials have also secured significant positions. All of these factors make them crucial partners for supporting the development of TSMC’s Kumamoto plant in the future.

In recent developments, an industry source revealed that Coherent, a leading chip material supplier in the U.S. automotive industry, has piqued the interest of four major Japanese corporate groups with regards to its silicon carbide (SiC) business, with a transaction amount potentially reaching $5 billion.

The four Japanese companies involved are DENSO, Hitachi, Mitsubishi Electric, and Sumitomo Electric, and discussions have been underway regarding the acquisition of minority stakes in Coherent’s SiC business.

Coherent had previously stated its intention to invest $1 billion over the next decade to expand the production of SiC wafers. Compared to traditional silicon chips, SiC wafers contribute to improved electric vehicle range. If this investment materializes, it would significantly ease the financial burden on the company. However, no concrete agreements have been reached at this stage.

Data indicates that Coherent is one of the few companies globally with complete and vertically integrated SiC manufacturing capabilities. It can produce SiC wafers and epitaxy materials, extending all the way to power devices. Furthermore, Coherent’s SiC materials are known for their exceptional quality, making it nearly the only supplier capable of transitioning from the current standard wafer diameter of 150 millimeters to 200 millimeters successfully. The production of larger diameter wafers can substantially reduce device costs. Additionally, Coherent’s SiC power devices demonstrate excellent heat resistance and conductivity.

Competition and Collaboration in the Japanese SiC Industry

According to TrendForce’s latest analysis, as collaborations between companies like Infineon and ON Semiconductor with automotive and energy sector stakeholders become more apparent, the overall SiC power device market is projected to reach $2.28 billion in 2023, growing at an annual rate of 41.4%.

Meanwhile, buoyed by robust demand in downstream application markets, TrendForce anticipates that the SiC power device market could reach $5.33 billion by 2026, with its primary applications continuing to center around electric vehicles and renewable energy.

In recent years, the new energy vehicle industry has been thriving, and Si power devices have gradually fallen short of meeting the demands of new energy vehicles. SiC, as its alternative, has shown remarkable performance in applications, making it highly sought after in the market. The SiC power device market still has considerable room for growth, prompting both automotive and SiC companies to invest in SiC power device production or enhancements.

Japan, being a leader in semiconductor power device manufacturing and production, has numerous companies actively expanding to broaden their market reach.

On October 4th last year, Nikkan reported that Hitachi Power Semiconductor Device would invest several billion yen, aiming to triple its SiC power semiconductor production capacity by fiscal year 2026.

On July 12th this year, ROHM announced its acquisition of the former Solar Frontier factory in Kunitomi, Miyazaki, to expand its SiC power semiconductor production capacity. The acquisition is set to conclude in October 2023 and is planned to become the company’s main factory, primarily producing SiC power semiconductors. It is expected to increase its silicon carbide capacity to 35 times that of the fiscal year 2021 by 2030.

With these competitive and cooperative scenarios unfolding, it’s evident that neither automotive nor SiC companies are holding back in their pursuit of SiC power device production or improvements.

In July this year, Renesas Electronics signed a 10-year agreement and paid $2 billion in advance to Wolfspeed for the supply of 150mm bare and epitaxial SiC wafers. Renesas Electronics also reached an agreement with Mitsubishi Electric, with Mitsubishi investing 260 billion yen in technology and expansion, including the construction of a new SiC factory in Japan.

As a technological leader in producing SiC substrates, epitaxy, and power devices, Coherent is not to be overlooked by these major corporations.

On May 26th this year, Coherent and Mitsubishi Electric announced that they had signed a MOU and reached a project collaboration agreement to jointly scale up the mass production of SiC power electronic products on a 200mm technology platform.

Mitsubishi Electric announced that it would invest approximately 260 billion yen over a five-year period ending in March 2026, with approximately 100 billion yen dedicated to constructing a new SiC power device factory based on a 200mm technology platform and strengthening related production facilities. According to the MOU, Coherent will develop 200mm n-type 4H SiC substrates for Mitsubishi Electric’s future SiC power devices to be produced at the new factory.

In the future, Mitsubishi Electric aims to produce large quantities of silicon carbide chips using Coherent’s 200mm wafer technology in the Japanese market.

In the 2023 fiscal third-quarter earnings conference call, Mary Jane Raymond, the Chief Financial Officer of Coherent Inc., mentioned that the revenue composition of the company’s four main markets is as follows, based on regional distribution: North America accounts for 53%, Europe accounts for 20%, Japan and Korea account for 14%, China accounts for 11%, and 3% goes to other regions worldwide.

For Coherent, capturing 14% of the sales in the Japanese and Korean markets is highly significant. If Coherent continues its collaboration with Japanese partners, it is highly probable that the production capacity of SiC power devices in Japanese-related companies will be increased. Additionally, this will allow Coherent to further expand its influence and presence in Japan.
