Reticle and manufacturing method of solid-state image sensor
Abstract:
A reticle includes a repetition pattern and a peripheral pattern, one of which has a first side in a first direction and the other a second side in the first direction. The first side has a first length that is n times the second length of the second side, where n is an integer equal to or larger than 1. The first pattern has at least one of first misalignment measurement patterns provided at positions distant by a third length and ((the third length)+(n−1).times.(the second length)) from an upper end of the first pattern. The third length is equal to or smaller than the second length. The second pattern has a second misalignment measurement pattern provided at a position distant by the third length from an upper end of the second pattern.
