Patent ID: 7569403

Claim:
A pattern evaluation method using a circuit arrangement provided with N (N is a natural number of 2 or greater) circuit groups having wiring whose widths are different to each other, each circuit group including first to Mth circuits having first to Mth (M is a natural number of 2 or greater) wiring formed of a conductive layer, respectively, each of the first to the Mth wiring having the same width that is electrically measurable, the pattern evaluation method comprising: arranging patterns to be evaluated so that the Mth wiring or a layer in the vicinity thereof is locally removed; electrically calculating a first characteristic value indicating a characteristic of the first circuit including at least the wiring width of the first wiring; electrically calculating an Mth characteristic value which is a value indicating the characteristic of the Mth circuit and dependent on a geometric relationship between the pattern to be evaluated and the Mth wiring; and evaluating the characteristic of the pattern to be evaluated based on the first characteristic value to the Mth characteristic value obtained for at least two circuit groups of the N circuit groups.
