Abstract:
A mask set includes a first mask and a second mask. The first mask includes geometric patterns. The second mask includes at least a strip-shaped pattern with a first edge and a second edge opposite to the first edge. The strip-shaped pattern has a centerline along a long axis of the strip-shaped pattern. The first edge includes inwardly displaced segments shifting towards the centerline and each of the inwardly displaced segments overlaps each of the geometric patterns.
