Enhanced uniqueness for pattern recognition
摘要:
The present invention describes a test structure with a first set of features which is a subset of product features; and a second set of features adjacent to the first set of features, the second set occupying a smaller area than the first set and the second set being similar to the first set yet being distinguishable from surrounding structures.
