Sony Semiconductor Solutions and TSMC announced on Friday the signing of a non-binding memorandum of understanding to establish a joint venture focused on developing and manufacturing next-generation image sensors, a move that sent Sony shares surging as much as 12% in Tokyo trading on Monday.
A “Fab-Light” Future
Under the proposed partnership, Sony will serve as the majority and controlling shareholder of the joint venture, which will set up development and production lines at Sony’s newly constructed fabrication plant in Koshi City, Kumamoto Prefecture. The venture combines Sony’s leading position in image sensor design with TSMC’s process technology and manufacturing capabilities.
CEO Hiroki Totoki described the partnership as the “first step to becoming fab-light,” according to Bloomberg, signaling Sony’s intention to reduce its in-house manufacturing footprint while preparing for growing demand for machine vision in the AI era. Totoki said at a briefing that Sony’s ability to supply image sensors has been constrained by its manufacturing capacity and that the company wants to be ready for future demand.
The two companies are still discussing potential investments by the joint venture. Those investments, along with new capital spending by Sony at its existing Nagasaki plant, would be phased according to market demand and are contingent on support from the Japanese government. The partnership will also explore opportunities in physical AI applications such as automotive and robotics.
Record Profit Forecast Fuels Rally
The joint venture announcement came alongside Sony’s corporate strategy and earnings presentation on Friday, where the company forecast record net profit of 1.16 trillion yen ($7.4 billion) for the fiscal year ending March 2027, a roughly 13% increase from the prior year. Sony also announced a 500 billion yen share buyback program.
Sony projected operating profit for its games division to climb 30% to 600 billion yen, driven by stronger sales of in-house software titles. The semiconductor business also contributed to the upbeat outlook, supported by firm demand for image sensors used in digital cameras and other devices.
Kumamoto’s Growing Chip Hub
The partnership deepens an already long-standing relationship between the two companies. TSMC Senior Vice President Kevin Zhang called Sony a “long-time partner in the CMOS image sensor business”. TSMC already operates in Kumamoto through Japan Advanced Semiconductor Manufacturing, its joint venture with Sony and other partners, which began volume production in late 2024. The new image sensor venture represents a further expansion of Kumamoto’s role as a hub for Japan’s semiconductor ambitions, backed by government investment aimed at rebuilding the country’s chip industry.
