Carl Zeiss

Foundation-owned optics manufacturer whose SMT division builds the projection-optics mirror system inside every ASML EUV lithography scanner — by the company's own account, optics behind roughly 80% of chips made worldwide and 100% of the most advanced EUV-made chips. The vault's central recurring thread on this entity is whether that dominance is best explained by tacit, cross-organizational institutional know-how (a moat that resists patents and resists imitation by Nikon and Canon) or by other factors — export-control-style scarcity, capital intensity, historical accident of consortium membership. First entered the vault 2026-07-11 via the sole- supplier and foundation-ownership claims below; deepened 2026-08-01 with a primary company technical document and two independent analysts' framing of the tacit-knowledge thesis, plus a correction of the specific Nikon/Canon causal story.

• 2026-08-01: A primary Zeiss SMT engineering slide deck (2011 EUV Lithography Symposium) confirms the company's own mirrors met an rms = 0.1nm surface-quality spec for the NXE:3300 generation, corroborating the order of magnitude of the sub-0.1nm roughness figure the vault had previously sourced only to a Tier-4 explainer (claim-zeiss-2011-slide-deck-confirms-0-1nm-rms-euv-mirror-surface-figure).
