ABSTRACT:
In a design rule checking method of the invention, pattern data for forming one layer is divided into two types of pattern data for an A layer and a B layer. Then, A rules to be satisfied by the pattern data for the A layer, B rules to be satisfied by the pattern data for the B layer, and AB rules to be satisfied by a combination of the two types of pattern data for the A and B layers are established. Then, based on the established rules, it is checked to see whether the pattern data for the A layer satisfies the A rules, whether the pattern data for the B layer satisfies the B rules and whether the combination of the two types of pattern data for the A and B layers satisfies the AB rules.
