Photolithographic system for semiconductor wafers corrects diffraction errors by phase filter in Fourier plane suits small structures |
摘要 |
A photolithographic system has a phase correcting filter (308) in the Fourier transform plane between two lenses (306,310) so that the image of the mask (304) projected on the semiconductor wafer (312) is corrected for diffraction effects.
