Lithographic apparatus and methods for use thereof |
摘要 |
A method for determining a polarization state of light passed through the projection lens of a lithographic apparatus is described. Polarizing structures are disposed on an object side of the projection lens of the lithographic apparatus. By measuring light that has passed through the polarizing structures information regarding the polarization characteristics of the projection lens can be determined.
