摘要:A metrology target of a miconductor device is provided. The metrology target includes a substrate including first and cond layers. The first layer includes a first grating, a cond grating, and a first dummy structure. The first dummy structure is at least formed between the first grating and the cond grating. The cond layer is formed over the first layer and includes a third grating and a fourth grating. The first, cond, third and fourth gratings are formed bad on the first spatial period. The third grating and fourth grating are placed to overlap the first grating and cond grating, respectively. The first grating and the third grating are formed with a first positional offt which is along a first direction. The cond grating and the fourth grating are formed with a cond positional offt which is along a cond direction which is opposite to the first direction.
