Abstract: An alignment mark is arranged to be within an image screen and the alignment mark is formed with rectangular patterns having varied dimensions from each other. The signal waveforms from each of the rectangular patterns are measured. The number of the rectangular patterns with normal waveforms is compared to the minimum required number of marks prescribed beforehand. The amount of deviation in alignment is calculated by excluding the abnormal measured result.
