Overview
For decades, Sony designed and built its own camera chips from start to finish. On August 11, 2026, it agreed to stop doing the second half alone.
Sony and Taiwan's TSMC will form a joint venture worth about $4.69 billion to make next-generation image sensors in Kumamoto, Japan. Sony keeps the pixel design and customers. TSMC brings the factory know-how. Volume production is targeted for 2029.
Why it matters
Sony makes the camera sensor in most high-end phones. How it builds the next generation shapes the cameras in your next several phones.

TSMC opens its first Japan fab in Kumamoto
BackgroundTSMC starts production at its JASM plant in Kumamoto, with Sony among the backers. The site becomes a growing hub for chipmaking in southern Japan.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
AMD spins off its factories to form GlobalFoundries (2009)
Chip designer AMD split off its manufacturing plants into a separate company, GlobalFoundries, backed by Abu Dhabi investors. AMD kept design and gave up the burden of funding leading-edge fabs.
AMD shed heavy factory costs and the debt tied to them.
AMD went fully fabless and later used TSMC to build competitive chips, recovering from years of losses.
Sony is making a lighter version of the same move: keep the design, share the factory. AMD shows going fab-light can free a design company to compete harder.
Sony takes a stake in TSMC's Kumamoto plant (2021)
When TSMC agreed to build its first Japanese fab in Kumamoto, Sony joined as a minority investor. The plant, called JASM, opened in 2024 with Japanese government support.
Sony secured a nearby chip supply and a working relationship with TSMC.
Kumamoto grew into a chipmaking cluster, setting the stage for the deeper 2026 venture.
The new venture builds directly on this earlier tie-up. Sony and TSMC already knew how to work together in the same prefecture.
IBM pays GlobalFoundries to take over its chip unit (2014)
IBM agreed to pay GlobalFoundries $1.5 billion to absorb its money-losing chip manufacturing operations. IBM kept research and chip design but exited high-volume production.
IBM removed a loss-making business from its books.
IBM stayed a chip innovator through research while others handled manufacturing.
Another case of a big electronics maker deciding it no longer needed to own every factory. Sony is choosing partnership over a full exit, but the logic of shedding capital cost is the same.
