Silicon Analysts Weekly for the week of 2026-06-29 to 2026-07-06: CoWoS-L hits 130k wpm; Nvidia Kyber delayed 12+ months to 2028. A sourced, provenance-marked briefing on AI-chip supply-chain and pricing movements — HBM spot prices, wafer pricing, foundry and CoWoS capacity, per-chip bill-of-materials cost, and HBM qualification status — derived from public data and human-reviewed. Part of the Silicon Analysts semiconductor data layer.
The take
CoWoS-L capacity is tracking 130k wafers/month in 2026 versus 105k at end-2025, with JPMorgan projecting 141k in 2027 — the tightest advanced-packaging constraint in the supply chain. Nvidia's Kyber NVL144 rack slip of 12-plus months to 2028 on circuit board challenges removes a near-term CoWoS demand pull-forward but opens space for competing architectures. Combined, the $518B Korea memory buildout and Micron's Japan expansion signal suppliers are betting capacity ahead of demand.
