300-mm Monolithic Silicon Photonics Foundry Technology
Abstract – A competitive 300-mm silicon photonics foundry technology has been developed by GLOBALFOUNDRIES for general availability, which takes advantage of advanced CMOS process technology and provides a manufacturing scale. A state-of-the-art process design kit offers a codesign environment with access to a comprehensive photonics device library along with a monolithically integrated SOI CMOS device library. Advances in automated wafer-level optical test enable statistical photonic device characterization for development, photonic modeling, and manufacturing controls. The key challenges and solutions in developing a manufacturable photonic technology with state-of-the-art performance are described, as well as a roadmap for next generation high-performance monolithic silicon photonics are outlined.
