Abstract
Defect inspection of EUV substrates and mask blanks must be controlled consistently to ensure repeatable and accurate defect counts. Initial sensitivity must be maintained without producing false counts. Various constructed and native defect monitors are created on substrates to track inspection tool performance. Remedies are applied to an inspection tool when monitors go out of control.
