ABSTRACT:
A large area dummy pattern DL is formed in a layer underneath a target T2region formed in a scribe region SR of a wafer. A small area dummy pattern in a lower layer and a small area dummy pattern Ds2in an upper layer are disposed in a region where the inter-pattern space of a pattern (active regions L1, L2, L3, gate electrode17), which functions as an element of a product region PR and scribe region SR, is wide. The small area dummy pattern Ds2in the upper layer is offset by ½ pitch relative to the small area dummy pattern Ds in the lower layer.
