Taiwanese foundry UMC is increasing its 2026 capital expenditure to $2 billion to expand capacity. The investment will fund the installation of a silicon photonics line at its Singapore fab and the construction of a new fab shell in Tainan, Taiwan, to meet strong future demand.

This Wire brief sits within Fusion42's coverage of Semiconductors.

◆ ◆ The Wire takeaway

The big foundries are adding capacity for specialty chips, not just the leading-edge nodes. UMC is building out a high-volume silicon photonics line, confirming it is a mass-market technology you can design your product around.
