Sony Semiconductor Solutions and Taiwan Semiconductor Manufacturing Company (TSMC) have formed a joint venture, Advanced Vision Semiconductor Manufacturing Corporation (AVSM), to develop and manufacture next-generation CMOS image sensors for mobile devices. Based in Koshi City, Kumamoto Prefecture, Japan, the new hub aims to give future smartphones DSLR-quality photography with instant AI processing, all within a thin, flat chassis, with volume production targeted for 2029.
Inside the Joint Venture
The hub was first revealed through a non-binding Memorandum of Understanding in May 2026. The financial and operational structure has now been confirmed: Sony will act as the sole controlling shareholder, operating AVSM as a consolidated subsidiary and appointing its Representative Director.
Sony plans to contribute approximately ¥465bn (US$2.9bn) through a combination of cash and asset transfers via a company split, while TSMC will contribute roughly ¥282bn (US$1.8bn) in phased cash investments tied to market demand. Additional capital needed to reach planned capacity is expected to be raised with financial support from the Japanese government.
The Invisible Engine Behind Mobile Photography
An image sensor acts as the electronic eye of a camera, capturing incoming light through a lens and translating raw photons into the digital data a phone turns into a photo or video. Unlike standalone cameras, mobile sensors must operate within extreme physical constraints, typically fitting a chassis less than eight millimetres thick.
To meet those constraints, modern smartphone camera systems use complex stacked sensor designs, where a top layer captures incoming light while a bonded bottom logic layer handles signal readouts, AI noise reduction and high-speed image processing. As cameras push toward higher megapixel counts, 8K video and computational photography, that logic circuitry must be fabricated on increasingly advanced process nodes — the core rationale behind the Sony-TSMC partnership.
"This joint venture is a significant initiative that brings together the strengths of both companies and aims to drive further advancement in technology and business within the next-generation image sensor field."— Shinji Sashida, President and CEO, Sony Semiconductor Solutions Corporation
