Overview
- Sony and TSMC signed a non-binding memorandum to create a joint venture that would place development and production lines at Sony’s new Koshi, Kumamoto sensor plant, with Sony expected to hold control.
- The venture targets stacked image sensors, which layer the light-sensing array over logic and memory for faster readout and on‑chip processing, for cars, robots and other physical AI devices.
- Investment would roll out in phases based on demand and possible Japanese government support reported at up to ¥60 billion, and the JV still requires a definitive contract and closing conditions.
- Sony is also weighing additional spending at its Nagasaki site to support the plan as both companies review how much to build and when.
- Combining Sony’s design leadership with TSMC’s advanced process technology marks a rare co-development step for TSMC and reflects rising pressure from Samsung’s recent Apple sensor wins.
