Fab Construction Milestones

Dated groundbreaking → equipment move-in → risk-production → HVM events, with schedule slips recorded as their own events.

Coverage window

2018-01-26 → 2026-08-19 (112 rows)

Computed from the backing series at page-render time — never typed by hand.

History honesty

Subject depth reaches 2018-01-26 via archive backfill (92 rows); continuous capture since 2026-07-19 (20 live rows).

Cadence

Weekly — the fab-milestone routine sweeps Fridays 11:08 Pacific; construction/ramp events (and schedule slips) land as foundries and governments disclose them.

Revision policy

Rows are immutable observations (freeze triggers). A wrong reading is corrected by appending a new row and registering the correction; review_status is the only mutable field.

Known gaps

Coverage concentrates on the leading-edge and memory majors (TSMC, Intel, Micron, SK hynix, Samsung) plus notable analog/power projects (Infineon, Texas Instruments, Bosch, Kioxia). China-domestic fabs (SMIC, Hua Hong, CXMT) are a known collection gap we intend to close, and advanced-packaging facilities (CoWoS lines, OSAT sites) are in scope but not yet systematically covered. Delays and schedule slips are first-class events recorded with the same sourcing bar as announcements. Live capture began July 2026; 92 of 106 events are archive backfill, flagged per row.
