Patent ID: 7427459

Claim:
A recticle pattern applied to a mix-and-match lithography process, the recticle having a transparent region and a non-transparent region surrounding the transparent region, the transparent region comprising a device region and a scribe line region surrounding the device region, the recticle pattern comprising: a plurality of device patterns, disposed on the device region; a portion of a first set of alignment measure figures, disposed on the corresponding scribe line region adjacent to the non-transparent region; a portion of a second set of alignment measure figures, disposed beside the portion of the first set of the alignment measure figures, comprising a first portion disposed on the corresponding scribe line region adjacent to the non-transparent region and a second portion disposed on the fringe of one of the two parallel opposite sides in the non-transparent region, wherein a portion of the first set and a portion of the second set of the alignment measure figures self-align after an exposure process to self-generate two sets of composite alignment measure figures on a wafer; and a set of overlay measure figures, used for correcting the overlay error produced by recticle rotation, the set of the overlay measure figures comprises four rectangular boxes having transparent regions of different sizes with a same center after being overlaid, and the four boxes being respectively disposed in four areas formed in the corners of where the non-transparent region and the scribe line region meet, Wherein the distance between the boxes disposed in the non-transparent region and the edge of the scribe line region is greater than or equal to the distance between the portion of the first set of the alignment measure figures, the portion of the second set of the alignment measure figures and the edge of the scribe line region.
