Global Silicon Photonics Wafer Foundry Market Strategic Research Report

Scope of the Report

The global Silicon Photonics Wafer Foundry market size is predicted to grow from US$ 475 million in 2025 to US$ 3,860 million in 2032; it is expected to grow at a CAGR of 33.4% from 2026 to 2032.

Silicon Photonics Wafer Foundry refers to wafer-level foundry services that provide process platforms, wafer fabrication, MPW shuttle runs, dedicated engineering runs, low-volume manufacturing and volume production for silicon photonic integrated circuits. The major process platforms include SOI-based silicon photonics, silicon/germanium-on-silicon photonic-electronic integration, silicon nitride photonics and heterogeneous integration platforms. These foundries fabricate photonic components such as optical waveguides, couplers, modulators, photodetectors, splitters, ring resonators and thermal tuners on semiconductor wafers, while supporting customers with PDKs, process libraries and design rules. The market scope should mainly cover wafer fabrication foundry revenue, excluding downstream optical modules, CPO systems, standalone packaging and testing services, pure design services and end-system revenue. In 2025, global silicon photonics wafer foundry shipments reached approximately 63.73 thousand equivalent 8-inch wafers, with an average ex-factory price of about USD 7,620 per wafer.

Silicon photonics wafer foundry is a specialized foundry business formed by the integration of semiconductor wafer manufacturing and photonic integration technologies. It mainly provides PDK support, MPW shuttle runs, dedicated engineering runs, low-volume manufacturing and volume production services for silicon photonic integrated circuits. Its major process platforms include SOI or silicon-based silicon photonics platforms, silicon nitride photonics platforms, and heterogeneous integration and other silicon-based photonics platforms. The fabricated photonic devices include optical waveguides, couplers, modulators, photodetectors, splitters, ring resonators and thermal tuners. Compared with traditional CMOS electronic IC foundry services, silicon photonics wafer foundry requires not only wafer-level uniformity and yield control, but also precise management of optical loss, coupling efficiency, polarization stability, thermal drift, photonic-electronic co-design, and packaging and testing compatibility.

At present, silicon photonics wafer foundry is still transitioning from R&D validation to commercial volume production, and its overall scale remains much smaller than that of CMOS logic foundry. Therefore, industry capacity should be described in terms of “effective commercial silicon photonics output capability” rather than the nominal capacity of semiconductor fabs. GlobalFoundries and Tower Semiconductor are currently among the most representative commercial silicon photonics foundry platforms, while imec, LioniX, SilTerra, VTT and IHP mainly play roles in MPW, prototyping, pilot production or specialty process platforms. With rising demand from AI data centers, high-speed optical modules, CPO and photonic-electronic integration, large semiconductor foundries such as TSMC, Samsung and UMC are also accelerating their silicon photonics platform development. Samsung further disclosed its progress in a 300mm silicon photonics foundry platform in 2026, while UMC is building a 12-inch silicon photonics platform by introducing imec’s iSiPP300 technology. As a result, the competitive landscape is shifting from specialized platforms toward broader participation by large-scale wafer foundries.

From the perspective of downstream demand, data center optical interconnects represent the most important growth area for silicon photonics wafer foundry. AI clusters, cloud computing and high-speed switching systems require higher bandwidth, lower power consumption and greater interconnect density, driving the adoption of silicon photonics in pluggable optical modules, CPO, OCS, scale-out and scale-up networks, and board-level optical interconnects. Non-data-center applications include telecom communication, coherent optical communication, LiDAR, industrial sensing, biosensing, quantum photonics and research projects. Although these orders are more fragmented and customized, they offer relatively high technical value. Since silicon photonics wafer foundry requires close coordination across process platforms, PDKs, packaging and testing, optical validation and customer qualification, its average gross margin is generally higher than that of conventional mature-node foundry services, typically in the range of approximately 25% to 40%. In the future, as 300mm platforms mature, customer orders ramp up and packaging and testing standardization improves, silicon photonics wafer foundry is expected to become a high-growth segment in photonic-electronic integrated semiconductor manufacturing.
