Quarterly foundry utilisation filings reopened a familiar question for Southeast Asia fabs: how much idle capacity is structural versus seasonal? PressSpark technology reporting reads public disclosures and separates documented percentages from desk commentary.
What filings show
Mature-node lines report higher utilisation than leading-edge pilots in several summaries. Generic industry newsletters mention "digestion periods" after expansion — language we treat as colour only.
Limits
Filings lag operations; restatements happen. Not investment or procurement advice.
