MPW / Shuttle access

SJ SEMI 40nm MPW

Plan a 40nm multi-project wafer run at SJ SEMI through TOMPW Service. We coordinate shared-mask access, EDA sign-off, shuttle scheduling and the downstream packaging or test path for global chip teams.

Node: 40nmMPW, NTO and production evaluation

Why 40nm

40nm is a cost-effective node with a large IP and PDK ecosystem, ideal for mainstream mixed-signal designs. TOMPW coordinates 40nm MPW runs for prototype and low-volume production.

Typical applications

✓Connectivity and RF ICs
✓PMIC and analog
✓Consumer and IoT chips
✓Industrial sensors

What a 40nm MPW at SJ SEMI involves

A 40nm 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 SJ SEMI's line on schedule.

✓BCD and HV platform coordination

✓Automotive-grade process support

✓Power IC and analog process access

✓Specialty mature-node production

COMMON QUESTIONS

Working with SJ SEMI 40nm MPW through TOMPW

Can TOMPW arrange a 40nm MPW shuttle at SJ SEMI?

Yes. TOMPW coordinates 40nm MPW and shuttle access at SJ SEMI for overseas teams, handling slot selection, EDA checks and logistics so your design reaches the shared mask on schedule.

What does a 40nm MPW run at SJ SEMI typically include?

A 40nm MPW run bundles your design onto a shared reticle with other projects, covering mask share, wafer fabrication at SJ SEMI, and standard probe. Packaging, final test and NTO transition are planned separately with TOMPW.

How long does a 40nm MPW cycle take at SJ SEMI?

Cycle time depends on SJ SEMI's shuttle cadence for 40nm, 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 40nm MPW at SJ SEMI?

After a successful 40nm MPW, teams typically move to NTO or full-mask production. TOMPW helps plan that transition, including package selection, test development and volume ramp through SJ SEMI and downstream partners.
