MPW / Shuttle access
SJ SEMI 0.25µm MPW
Plan a 0.25µm 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.
Why 0.25µm
0.25µm is one of the process options TOMPW coordinates as a shared-mask MPW run at the partner foundry. We handle slot selection, EDA checks and logistics so your design reaches the line on schedule.
What a 0.25µm MPW at SJ SEMI involves
A 0.25µm 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.

Working with SJ SEMI 0.25µm MPW through TOMPW
Can TOMPW arrange a 0.25µm MPW shuttle at SJ SEMI?
Yes. TOMPW coordinates 0.25µm 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 0.25µm MPW run at SJ SEMI typically include?
A 0.25µm 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 0.25µm MPW cycle take at SJ SEMI?
Cycle time depends on SJ SEMI's shuttle cadence for 0.25µm, 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 0.25µm MPW at SJ SEMI?
After a successful 0.25µm 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.
