ABSTRACT:
A test vehicle comprises at least one product layer having a east one product circuit pattern on the product layer, and one or more clone layers formed over the product layer (1902). The one or more clone layers include a plurality of structures, which may include clone test vehicle circuit patterns and/or clone test vehicle vias (1902). The presence of one or more defects (1904) in the one or more clone layers (1908) is an indicator of a tendency of the product circuit pattern to impact yield of a succeeding layer to be formed over the product circuit pattern in a product (1910).
