Notes

  • Sai Micro is the China-based MEMS manufacturing arm of Sai MicroElectronics; Silex Microsystems (Sweden, already a TOMPW partner) is its subsidiary.
  • MEMS engagements are process- and design-based rather than standard CMOS MPW shuttles; TOMPW can help scope a Sai Micro MEMS program.

Why This Profile Exists

This profile exists so a team can review foundry-specific context directly, while still understanding TOMPW's role in execution, comparison and downstream supply-chain coordination.
