Installed 300mm capacity worldwide, actual 300mm wafers
SEMI on 2028. 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.
On the record now
Issued 2025-06-25 by SEMI · 300mm Fab Outlook, SEMI press release, 25 June 2025
Wafer basis: 300mm actual. That is this record's reading of which report the figure came from. NOT the publisher's words, and recorded as such. The releases say "wafers per month" without qualifying it; the basis follows from the product they come from - SEMI's 300mm Fab Outlook covers 300mm lines only, and a series counting one wafer size has nothing to convert to equivalents. That reasoning is this record's, so it is written here rather than presented as a quotation. If it is ever shown to be wrong, every figure on this subject is wrong by a factor of 2.25.
Everything published for this period
1 statement, so this figure has been published once and not yet restated. That is a fact about the publisher, not a gap in this record. Ordered by the date each was issued.
| Issued | Value as published | Source | |
|---|---|---|---|
| 2025-06-25 | 11.1 million wpm | first on the record | 300mm Fab Outlook, SEMI press release, 25 June 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.
Cite this
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.
