Patent ID: 8765361

Claim:
A method of manufacturing a solid-state image sensor, comprising: setting a wafer and a reticle to an exposing instrument, wherein the reticle includes; a repetition pattern comprising a pixel portion of an the solid-state image sensor, and a peripheral pattern comprising a peripheral circuit portion of the solid-state image sensor, wherein one of the repetition pattern and peripheral pattern is a first pattern with a first side in a first direction and the other is a second pattern with a second side in the first direction, the first side having a first length equal to or longer than a second length of the second side, wherein the first length is n (n is an integer equal to or larger than 1) times as large as the second length, wherein 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)×(the second length)} from an upper end of the first pattern, the third length being equal to or smaller than the second length, and wherein 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; exposing the repetition portion multiple times on the wafer; exposing the peripheral pattern on the wafer; and carrying out an automatic misalignment measurement using the at least one of first misalignment measurement patterns and the second misalignment measurement pattern.
