Sony will contribute approximately 465 billion yen ($2.92 billion) through direct capital injection and asset contributions, while TSMC will allocate roughly 282 billion yen ($1.77 billion), establishing a combined capital base of 747 billion yen. Sony will retain majority ownership, with the new entity operating as a Sony subsidiary under the current framework.

Following the announcement, TSMC shares declined 0.37% while Sony shares advanced 1.53%.

Advanced Vision Semiconductor Manufacturing Corp

The joint venture, officially named Advanced Vision Semiconductor Manufacturing Corp, will be headquartered in Kumamoto prefecture—the same region where TSMC currently operates its Japan Advanced Semiconductor Manufacturing (JASM) facility. Financial contributions will be deployed incrementally, aligned with market dynamics and operational requirements.

Sony to Lead Technology Development

Under the partnership terms, Sony will lead the development of fundamental image sensor technologies, including strategic product roadmaps and architectural design. TSMC will provide its semiconductor fabrication expertise and advanced manufacturing processes to enable high-volume production.

Sony is already the world's largest supplier of CMOS image sensors, holding a majority share of a global market in which Samsung Electronics ranks second. The partnership with TSMC potentially tightens Sony's grip on the sector by adding the world's leading pure-play foundry as a manufacturing partner for advanced sensor nodes, at a time when image sensor demand is extending beyond smartphones into automotive vision, augmented reality, and industrial automation systems.

The facility will specialize in smartphone image sensors, with volume manufacturing projected to begin in 2029. Both companies indicated they are evaluating supplementary financing options contingent on securing Japanese government incentives to achieve maximum planned production capacity.

TSMC's Manufacturing Role

TSMC's participation centers on manufacturing technology and production capabilities rather than product design. This structure allows Sony to maintain commercial oversight while leveraging TSMC's advanced semiconductor fabrication infrastructure.

The partnership was initially disclosed in May, with Tuesday's statement providing comprehensive financial terms and the official organizational framework.

Sony has been directing significant resources toward its imaging sensor division as machine vision applications expand within artificial intelligence ecosystems. The joint venture is designed to reduce Sony's standalone capital requirements while simultaneously expanding manufacturing scale.

The Kumamoto location leverages TSMC's existing Japanese operations, providing the partnership with immediate infrastructure advantages. TSMC's JASM fab in Kumamoto has received substantial support under Japan's semiconductor industrial strategy, which has channeled billions of dollars in subsidies to rebuild domestic chip production capacity—a policy context that directly underpins the joint venture's stated reliance on government incentives for maximum capacity expansion.

Neither company disclosed specific production volume projections, noting that capital deployment would align with evolving market conditions and operational considerations.
