发明名称 Three-direction alignment mark
摘要 A semiconductor device includes a first material formed on a substrate. The first material includes a first alignment mark. The first alignment mark includes alignment lines in at least three directions. The semiconductor device further includes a second material comprising a second alignment mark. The second alignment mark corresponds to the first alignment mark such that when the second alignment mark is aligned with the first alignment mark, the second material is aligned with the first material.
