What is UMC/SILITH 12-Inch Mass-Produced Silicon Photonics Wafers?

UMC and SILITH's 12-inch silicon photonics wafers are large-diameter semiconductor wafers manufactured using standard CMOS fabrication processes to produce photonic integrated circuits, components such as waveguides, modulators, and photodetectors that route and manipulate light on a chip, enabling optical components to be built at the same wafer scale and cost efficiency as conventional electronic chips.
