Node / Wafer DPW Comparison

Lock your die size and compare how many dies fit — and what each die costs — across wafer sizes. A quick way to reason about 200 mm vs 300 mm and find the sweet spot for your volume and budget.

Larger wafers fit far more dies, but cost more — the $/die column shows the trade-off for your specific die. Edit wafer cost per size to model your quoted prices.

WHY WAFER SIZE MATTERS

The 8-inch vs 12-inch effect

For the same die, moving to a larger wafer roughly doubles usable area. The calculator below turns that into exact DPW and $/die for your dimensions.

Larger wafers roughly double usable area, so $/die can drop 30–40% at volume — but wafer cost rises too. Compare on the calculator for your exact die.

What to watch

  • Moving from 200 mm to 300 mm roughly doubles usable area, but wafer cost rises too — compare $/die, not just DPW.
  • Small dies gain the most from larger wafers; very large dies are edge-limited either way.
  • For MPW/shuttle, the right wafer size is also driven by which shuttles your target foundry actually runs.

See which foundries run which shuttles on the MPW schedule page.

These are industry reference ranges, not a quotation and not an offer.

  • Every band on this page is deliberately wide. It is published so you can sanity-check whether a programme is realistic before you write to anyone — not so you can budget against it.
  • Actual pricing moves with the season and with capacity. Foundry and OSAT utilisation changes month to month, and a window that is cheap in a soft quarter can be materially more expensive in a tight one.
  • Mask, substrate, leadframe, gold, copper and tester-time costs all move independently of the node you chose.
