Market intelligence behind the moves
All market intelligence →TSMC CoWoS 5.5x Reticle Hits 98-99% Yield in Volume Production; 14x Roadmap Confirmed to 2029
Yield: CoWoS 5.5x reticle confirmed at 98-99% in volume production (positive); Roadmap: 14x reticle-size CoWoS targeted by 2029; SoIC pitch: 6 microns currently in HVM, targeting 4.5 microns by 2029.
TSMC CoWoS Yield Confirmed at 98-99% in HVM; Nvidia Weighs 8-Stack HBM4E Fallback for Rubin Ultra
CoWoS yield: 98-99% confirmed in HVM (positive); HBM4E 12-stack yield risk flagged — potential stack-count reduction from 12 to 8 layers (est. HBM capacity-per-die reduction of ~33% if downgrade confirmed); TSMC 2026 CapEx raised to $60-64B record (capacity positive).
Samsung HBM4 Hits 80% 'Golden Yield' — Four Months Ahead of Schedule, Supply Tightness Set to Ease
Yield improvement: Samsung HBM4 from <60% (Feb 2026 launch) to ~80% (Aug 2026) — approx. +20 pp in ~6 months; SK Hynix HBM4 yield also reported at ~80%; HBM4E target set at 70% pre-launch (H1 2027). 2027 HBM supply for all three vendors reported as fully booked.
SK Hynix 54 Trillion Won CapEx Locked In; Nvidia Rubin Ultra Downgrading HBM Stack Amid Structural Supply Crunch
CapEx: +54 trillion KRW (~$39B) across Y2 and M17 fabs; HBM capacity additions: Y1 initial production February 2027, M17 December 2028, Y2 June 2029 (plus 12–18 months yield ramp each); Contract DRAM prices: +90–95% QoQ in Q1 2026 (largest single-quarter spike on record per TechTimes); Nvidia Rubin Ultra HBM stack: downgraded from 16-stack HBM4E to 12-stack or 8-stack variants under evaluation; Lam Research advanced packaging revenue outlook raised from >40% to >70% YoY growth in current fiscal year.
Recent corrections
Full changelog →Methodology
Every day we freeze the canonical semiconductor cost/pricing data into an append-only ledger. This page compares the most recent snapshot against the closest one ~30 days earlier and surfaces the metrics that moved past a per-dataset significance threshold (filtering out rounding noise).
Each movement shows direction, magnitude (percent for value metrics, percentage-points for rate metrics), the two dates compared, and a confidence tier. The trend column sketches each metric's full ledger history (up to ~90 days). The history is young — the ledger began 2026-06-06, and some domains are tracked from later dates — so a 30-day window automatically clamps to the data available and labels the real lookback, and per-row trends can start on different dates. Underlying values are synthesized from public sources only.
Programmatic access: /api/v1/changes and the get_recent_changes MCP tool. For data provenance and terms, see Terms & Data Provenance.
