• Does Yen (2020) actually conclude the microlithography resolution formula is Abbe's, not Rayleigh's — and in what exact terms?

• Is the EUV mirror advantage genuinely tacit institutional know-how (not IP), and is the sub-0.1nm RMS roughness figure accurate?

• A named Tier-2 analyst (Burja) and a Tier-3 CEIPI-hosted piece independently characterize the ASML/Zeiss EUV advantage as resting on tacit, cross-organizational know-how rather than patents as the primary protective mechanism

• Carl Zeiss SMT's own 2011 technical presentation confirms an EUV mirror surface-figure specification of rms = 0.1nm, corroborating the order of magnitude of the vault's earlier sub-0.1nm roughness figure

• A 2020 peer-reviewed history attributes lithography's governing resolution formula to Abbe's 1870s diffraction work, not Rayleigh — the limit that forced EUV's 13.5nm wavelength
