Patent ID: 7495457

Claim:
A semiconductor device evaluation method of a semiconductor device evaluation apparatus for evaluating observed objects including an error position arranged on a semiconductor substrate, comprising: a first step of detecting electric information of the observed object including the error; a second step of calculating integrals based on the electric information in at least first and second directions among directions in which arrays of the observed objects are arranged, detecting a first integral-waveform obtained by calculating the integral in the first direction and detecting a second waveform obtained by calculating the integral in the second direction, wherein the first waveform includes a first peak which contains the array of the observed objects including the error position and is larger than at least one of other peaks, and wherein the second integral-waveform has peaks of substantially the same height; a third step of counting peaks of the second waveform caused while moving the semiconductor substrate in a direction for maintaining the peak of the first waveform that contains an array of the observed objects including the error position; and a fourth step of calculating a total number of the peaks regarding both vertical and lateral directions of the semiconductor substrate while the semiconductor substrate is moved from the error position to a predetermined reference position in the third step.
