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

  • Monolithic integration of 90 nm SOI CMOS library with a broad photonic device library
  • Starting SOI substrate: 2 µm BOX, 170 nm SOI for CMOS and photonic devices
  • Ge EPI integration coupled into SOI WG
  • 48 mask levels. 40 mask levels with hybrid option (photonics only)
  • 7 BEOL levels. 6 Cu, 1 AL.
  • Far-BEOL V-groove integration for fibre attach
