Fabrication and packaging sites
4 site(s) recorded on the fab map: 4 operating. Grouped by the status each site is published under, in the same order on every page. The order is not a judgement about which sites matter. A site run by a joint venture appears on every partner's page.
Operating 4
| Site | Location | Wafer | Nodes | First output |
|---|---|---|---|---|
| Xiamen Fab | Xiamen, Fujian, China | 300 mm | 40nm, 28nm | 2016 |
| Fab 12i | Pasir Ris Wafer Fab Park, Singapore | 300 mm | 22nm, 28nm | 2026 |
| Fab 8AB | Hsinchu Science Park, Taiwan | 200 mm | 0.13um, 90nm | not recorded |
| Fab 12A | Tainan Science Park, Taiwan | 300 mm | 40nm, 28nm, 22nm, 14nm | 2003 |
Node bands
Nodes are recorded on 4 of the 4 sites here. Which bands those nodes fall into, under each definition this record holds. A band is a publisher's statement on a date and not this record's classification: N7 was the leading edge when it arrived and is ordinary now, and nothing about the node changed. So the answer is computed against each definition and shown with the date of it.
Outside every band in this scheme: 14nm, 22nm, 28nm, 40nm, 90nm, 0.13um. This scheme defines only the bands above, so these are unclassified BY IT rather than placed in the nearest one.

Named in a headline
A literal text match on the company's name, counted and not curated. It misses items that discuss the company without naming it, and collects items that only mention the name. It is not a measure of coverage.

How these lists are built
Matched on the company's name in the headline, counted and not curated. This is a literal text match: the name as written, or the same name in capitals, and nothing else. It is not a judgement about what an item is about, so it misses items that discuss the company without naming it, and collects items that only mention the name. It is not a measure of coverage. Strings matched: UMC, United Microelectronics.
Sites are joined by the operator string in the fab data, which is declared per operator rather than matched, because a third of those strings are not a company name.
