SEMI process-node bands, 2025-06-25
How one publisher grouped process nodes on one date, in its own words. This is a statement with a date on it, not a classification this record owns.
The bands, as published
Issued 2025-06-25 by SEMI · 300mm Fab Outlook, SEMI press release, 25 June 2025
| Band | As published | From | To |
|---|---|---|---|
| Advanced | 7nm and below | 7 nm | |
| 2nm and below | 2nm and below | 2 nm |
Wafer basis: 300mm actual. The capacity figures this scheme is used with are counted on that basis.
The two bands here NEST: 2nm-and-below is a subset of 7nm-and-below and their capacities are never added. This scheme is on a different wafer basis from the January one, so its bands and that one's are not interchangeable either.
Why this is a statement and not a label
"Leading edge" is not a property of a node. It is a property of a node AT A DATE. N7 was the leading edge when it arrived and is ordinary now, and nothing about the node changed: the boundary moved past it. A fab tagged 'leading edge' in its own row would therefore be wrong later without anything having been edited, and would be wrong silently, which is the failure this record exists to avoid. So a fab holds the nodes a publisher said it runs, this file holds what a publisher said the bands were and when they said it, and the classification is the JOIN of the two — computed when a page is drawn and rendered with the date of the definition it used.
What the record shows so far
Across the two SEMI releases held here the 7nm-and-below boundary has NOT moved. What happened instead is that a finer band appeared beneath it: the June 2025 300mm Fab Outlook reports 2nm-and-below separately for the first time in this record. That is what the leading edge moving looks like in a publisher's own reporting, and it is the reason this file records bands as statements rather than as a fixed set of three.

The bands, the publisher, and the date they were published. A band quoted without its date is the failure this page exists to prevent: the boundary moves and the wording does not.

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.

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.
