TSMC and Sony Team Up on Next-Gen Image Sensor and New Production Lines for AI

Sony Semiconductor Solutions and TSMC have signed a non-binding memorandum of understanding to form a joint venture focused on next-generation image sensor development and manufacturing. Sony will be the majority and controlling shareholder in the joint venture, which plans to set up development and production lines at Sony’s newly built fab in Koshi City, Kumamoto Prefecture. The partnership brings together Sony’s image sensor design expertise and TSMC’s process technology and manufacturing scale. Beyond conventional imaging, the two companies are also looking at opportunities in physical AI applications, automotive and robotics specifically, where high-performance sensing is becoming increasingly important. Investment plans for the joint venture are still being worked out, and Sony is also considering additional capital investment in its existing Nagasaki plant. Both are being planned in phases based on market demand and are contingent on Japanese government support. Earlier reporting from Reuters indicated Japan’s Ministry of Economy, Trade and Industry (METI) has confirmed subsidies of up to ¥60 billion (around $380 million) for Sony’s Kumamoto image sensor facility.

The timing makes sense for both sides. TSMC is already involved in Kumamoto through its first fab there, which entered mass production in late 2024 supplying Sony Semiconductor Solutions and DENSO on 22/28 nm and 12/16 nm nodes. The new joint venture would push that relationship into more advanced territory. For Sony, the move comes as competitive pressure in the image sensor market is building as Samsung has been gaining ground in supplying sensors for Apple, squeezing Sony’s position in a segment it has long dominated. However, the joint venture still needs a definitive legally binding agreement before it’s official.
