A method for measuring a semiconductor device is provided. A method for measuring a semiconductor device includes defining an interest area and an acceptable area in a chip area on a wafer; performing a first measurement of the chip area with a spectral imaging device to acquire spectrum data of the chip area; assuming the distribution of the spectrum data of a first pixel in the acceptable area is a normal distribution; calculating a distance from a central point on the normal distribution to second pixels in the interest area; selecting a position of a second pixel having a distance from the central point on the normal distribution greater than a predetermined range, among the second pixels, as a candidate position; and performing a second measurement of the candidate position.
