TSMC sees SiPh going mainstream in 2027

The mainstream adoption of silicon photonics will fundamentally reshape the semiconductor packaging ecosystem, with TSMC poised to strengthen its leadership in advanced packaging. The surge in AI compute demand is driving explosive growth in optical transceiver markets, making SiPh a critical interface between chips and optical modules, forcing upstream equipment, materials, and midstream packaging facilities to accelerate upgrades. The geopolitical landscape of China Taiwan/ Taiwan, China and global supply chain adjustments will impose compliance risks, especially under export controls on key equipment, compelling companies to pre-emptively secure alternative pathways. Competitors like Amkor and UMC may ramp up SiPh investments to gain market advantage. Over the next 12-24 months, SiPh will transition from niche to mainstream applications, pushing the entire industry toward higher integration and lower power consumption, establishing new technological moats.
