Installed wafer fab capacity worldwide, 200mm-equivalent wafers
SEMI on 2025. Every value ever published for this period, in the order it was issued. Nothing here is computed: no delta, no percentage, no judgement about the movement.

Issued 2025-01-07 by SEMI · World Fab Forecast, SEMI press release, 7 January 2025
Wafer basis: 200mm equivalent. That is the publisher's own words. The publisher's own words. SEMI's World Fab Forecast releases state the basis with the figures: the 18 June 2024 release writes "33.7 million wafers per month (wpm: 8-inch equivalent)" inline, and the 7 January 2025 release carries the footnote "200mm equivalent". So this basis is quoted, not deduced.
Everything published for this period
2 statements. Ordered by the date each was issued.
| Issued | Value as published | Source | |
|---|---|---|---|
| 2024-06-18 | 33.7 million wafers per month (wpm: 8-inch equivalent) | first on the record | World Fab Forecast, SEMI press release, 18 June 2024 |
| 2025-01-07 | 33.6 million wafers per month (wpm) Second statement of the same target year, seven months later. | restated | World Fab Forecast, SEMI press release, 7 January 2025 |
The result
No result for this period is on the record. That means this record does not hold one, which is not the same as the publisher not having reported one.

The figure, the publisher, the date it was issued, the source, and what it replaced. The last of those is the part no other source can give you. Every qualifier the publisher attached travels with it.

One line. The value is deliberately not repeated here: on a slide the number is on the slide, and a footnote that restates it is one edit away from disagreeing with it.

Two lines, tab separated: the headings and one row. Tabs rather than commas because several of these values contain commas, and quoting rules are a second thing to get wrong. The columns do not line up on screen and do line up once pasted.
