Tower Semiconductor has announced a dual-track expansion of its 300mm silicon photonics, silicon germanium, and advanced packaging operations in Japan, committing up to $3 billion net of grants with backing from the country's Ministry of Economy, Trade and Industry (METI). Alongside the announcement, the Israeli specialty foundry raised its 2028 business model to approximately $3.6 billion in revenue and $1.2 billion in net profit, and it says those targets rest entirely on the first of the plan's two tracks: reviving the shuttered Arai fab it inherited from Panasonic and maximizing its running 300mm fab in Uozu, Toyama Prefecture.

Two tracks, one committed
