发明名称 Alignment marks for polarized light lithography and method for use thereof
摘要 Mark and method for integrated circuit fabrication with polarized light lithography. A preferred embodiment comprises a first plurality of elements comprised of a first component type, wherein the first component type has a first polarization, and a second plurality of elements comprised of a second component type, wherein the second component type has a second polarization, wherein the first polarization and the second polarization are orthogonal, wherein adjacent elements are of different component types. The alignment marks can be used in an intensity based or a diffraction based alignment process.
