Abstract

Targets or test structures used for measurements in semiconductor devices having long lines exceeding design rule limitations are divided into segments. In one embodiment, the segments have periodicity in a direction parallel to the length of the lines. In another embodiment, the segments of test structures in adjacent lines do not have periodicity in a direction parallel to the length of the lines. The lack of periodicity is achieved by staggering segments of substantially equal lengths in adjacent lines, or by dividing the lines into segments having unequal lengths. The test structures may be formed in scribe line regions or die regions of a semiconductor wafer.
