    摘要: A method and apparatus evaluates the runability of a photomask inspection tool that inspects plural sets of die, each die having a standard simulated industrial device feature at plural technology nodes. A technology node size is determined for each feature at which inspection by the tool provides no false detection of faults. A sensitivity module included on a photomask test plate along with a runability module allows determination of inspection tool sensitivity and runability in a single test sequence.
