ABSTRACT:
Disclosed is a semiconductor die having a scanning area. The semiconductor die includes a first plurality of test structures wherein each of the test structures in the first plurality of test structures is located entirely within the scanning area. The semiconductor die further includes a second plurality of test structures wherein each of the test structures in the first plurality of test structures is located only partially within the scanning area. The test structures are arranged so that a scan of the scanning area results in detection of defects outside of the scanning area.
