中文摘要 | the correlation between the coma sensitivity of the alternating phase-shifting mask (alt-psm) mark and the mark's structure is studied based on the hopkins theory of partially coherent imaging and positive resist optical lithography (prolith) simulation. it is found that an optimized alt-psm mark with its phase width being two-thirds its pitch has a higher sensitivity to coma than alt-psm marks with the same pitch and the different phase widths. the pitch of the alt-psm mark is also optimized by prolith simulation, and the structure of p - 1.92 lambda/na and pw = 2p/3 proves to be with the highest sensitivity. the optimized alt-psm mark is used as a measurement mark to retrieve coma aberration from the projection optics in lithographic tools. in comparison with an ordinary alt-psm mark with its phase width being a half its pitch, the measurement accuracies of z(7) and z(14) apparently increase.
