Global Foundries Silicon Photonics (9WG)

Description

The GLOBALFOUNDRIES (GF) silicon photonics (SiPh) foundry portfolio is designed to help you deliver more data faster, farther and more efficiently than traditional CMOS technologies. 9WG is an industry-first SiPh foundry solution. Built on a 90 nm SOI platform, the offering enables you to leverage high-volume manufacturing along with advanced processing and controls that utilize proven CMOS manufacturing methodologies and infrastructure.
CMC Microsystems offers access to GLOBALFOUNDRIES technologies via its cost-shared multi-project wafer runs.

Process Overview
