Taiwan Semiconductor Manufacturing Co (TSMC) and Sony Group are considering a combined investment of about ¥1 trillion (US$6.3 billion) to develop an image sensor manufacturing facility in Japan, as demand for sensing technologies grows across artificial intelligence (AI), automotive and robotics applications.
The proposed investment would support a planned facility in Kumamoto Prefecture in southern Japan, with the two companies targeting the start of production in 2029, according to people familiar with the discussions.
The investment amount is still under consideration, and the companies have not disclosed a specific schedule for deploying the funds.
The planned expansion is aimed at capturing growing demand for image sensors from emerging applications, particularly AI-enabled robots and autonomous vehicles.
These systems rely on sophisticated sensors to perceive and interpret their surroundings, creating new growth opportunities for manufacturers of image sensing technologies.
TSMC and Sony announced in May that they were exploring the possibility of establishing additional production lines and development facilities within Sony's existing image sensor manufacturing complex in Kumamoto.
The proposed collaboration would build on the companies' existing relationship in Japan and strengthen their ability to address demand from next-generation applications.
The proposed joint venture could also support Sony's strategy of reducing the capital burden associated with maintaining and expanding its image sensor operations.
Sony has established a strong position in the premium image sensor market, supplying components to major technology companies and smartphone manufacturers. The company is now looking to broaden its presence in sectors such as automotive and robotics, where demand for advanced sensing technologies is expected to increase.
Under the proposed structure, Sony would remain the controlling shareholder of the new venture, while TSMC would participate as a partner.
The arrangement could allow Sony to expand its sensor business while sharing some of the investment requirements with TSMC. For TSMC, meanwhile, the partnership would provide an additional source of long-term business from the growing image sensor market.
Japan's government is also considering financial support for the planned venture, according to Japan's Minister of Economy, Trade and Industry Ryosei Akazawa.
The potential sensor investment comes as TSMC continues to benefit from strong demand for advanced semiconductor technologies driven by AI.
The company reported monthly sales of NT$467.58 billion (US$14.51 billion) for July, representing a 44.7 per cent increase year on year and a 5.6 percent rise from June.
For the first seven months of 2026, TSMC's cumulative revenue reached NT$2.87 trillion, up 37 per cent compared with the same period a year earlier.
The company's latest-generation manufacturing technologies, including its 2nm process, have contributed to the increase as customers accelerate the development and production of advanced chips for AI and high-performance computing.
TSMC has also raised its expectations for the year, reflecting continued confidence in the strength of AI-related semiconductor demand. The company now expects capital expenditure of between US$60 billion and US$64 billion in 2026 and is forecasting full-year revenue growth of slightly more than 40 per cent in US dollar terms.
The proposed partnership with Sony would therefore extend TSMC's strategic involvement in Japan beyond conventional logic chip manufacturing, while allowing both companies to capitalise on the expanding role of image sensors in AI, autonomous mobility and robotics.
