What it is

UMC is Taiwan's second-largest and the world's number-three pure-play foundry, specializing in mature and specialty process technologies (22/28nm, RF, embedded, display drivers) rather than leading-edge logic. It plays a supporting role in the AI supply chain via peripheral and analog components. In 2024-2025 it partnered with Intel to co-develop a 12nm US-manufactured platform, expanding its geographic diversification beyond Taiwan.

Times are New York time. Free sources are pulled on the schedule shown by the pipeline runner (data/corpus/run_pipelines.py), which logs every run; paid sources run only with the owner's yes; filings and newsroom pages are re-read when a new document is filed.

Links come from the AI Systems Map ontology. Deals carry the filing's own wording and a quote, checked against the document; latest source 2026-10-26. Not investment advice.
