MPW / Shuttle access

UMC 28nm MPW

Plan a 28nm multi-project wafer run at UMC through TOMPW Service. We coordinate shared-mask access, EDA sign-off, shuttle scheduling and the downstream packaging or test path for global chip teams.

Why 28nm

28nm is a mature, high-yield CMOS node that balances performance, power and cost for high-volume SoCs. TOMPW coordinates 28nm MPW shuttles so teams can validate silicon before committing to full mask.

Typical applications

✓Mobile and consumer SoCs
✓IoT and wearable chips
✓Wireless connectivity (WiFi/BT)
✓Automotive and industrial MCUs
✓Mixed-signal and RF peripherals

What a 28nm MPW at UMC involves

A 28nm MPW (multi-project wafer) shuttle places several customer designs on one shared mask set, so each team pays only for its portion of the wafer. TOMPW Service handles slot selection, DRC/LVS review and logistics so your GDSII reaches UMC's line on schedule.

Notes for 28nm programs

UMC is especially strong for mixed-signal programs that do not require advanced nodes.
TOMPW can coordinate multi-project wafer runs to reduce NRE.

COMMON QUESTIONS

Working with UMC 28nm MPW through TOMPW

Can TOMPW arrange a 28nm MPW shuttle at UMC?

Yes. TOMPW coordinates 28nm MPW and shuttle access at UMC for overseas teams, handling slot selection, EDA checks and logistics so your design reaches the shared mask on schedule.

What does a 28nm MPW run at UMC typically include?

A 28nm MPW run bundles your design onto a shared reticle with other projects, covering mask share, wafer fabrication at UMC, and standard probe. Packaging, final test and NTO transition are planned separately with TOMPW.

How long does a 28nm MPW cycle take at UMC?

Cycle time depends on UMC's shuttle cadence for 28nm, usually a few months from mask data to returned wafers. Missing a window means waiting for the next one, so TOMPW recommends booking early.

What comes after a 28nm MPW at UMC?

After a successful 28nm MPW, teams typically move to NTO or full-mask production. TOMPW helps plan that transition, including package selection, test development and volume ramp through UMC and downstream partners.
