COMMON QUESTIONS

Working with UMC through TOMPW

Can TOMPW arrange MPW or shuttle runs at UMC?

Yes. TOMPW coordinates MPW, NTO and full-mask access at UMC for overseas chip teams, handling scheduling, EDA checks and logistics.

What support does TOMPW provide beyond the wafer at UMC?

Packaging, final test, PCB support and turnkey assembly coordination through the foundries we coordinate, so the customer sees a simpler handoff path.
