Abstract:
1. An original plate evaluation method for evaluating an original plate comprising a substrate and a plurality of patterns provided on the substrate and corresponding to a plurality of circuit patterns to be formed on a semiconductor substrate, the plurality of patterns including N (N≧2) patterns differing from one another in at least one of a shape and an arrangement position in the substrate, the original plate evaluation method comprising: selecting N1 patterns from the N patterns (N1≦N) based on a first selection criterion; acquiring measured values for the N1 patterns; performing a first determination configured to determine whether or not the acquired measured values satisfy a first specification value; selecting N2 patterns from the N patterns (N2≦N) based on a second selection criterion; acquiring images relating to the N2 patterns, and predicting the shapes of transfer patterns based on the acquired images; performing a second determination configured to determine whether or not the predicted shapes of the transfer patterns satisfy a second specification value; and evaluating the original plate based on the first determination and the second determination.
