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.

  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]]).
