| Abstract: | Alignment system is the most sophisticated part of stepper, and understanding the principles of alignment is one of the keys to using and designing lithography machine. In the paper, firstly we in-troduce the alignment system of Nikon stepper. then compare three styles of alignment in Nikon step-per: LSA、FIA、LIA, at last, combined with mathematical models of Nikon stepper alignment to ana-lyze alignment signal intensity for improving the accuracy of alignment, the results provide a certain guiding function for the practical application. |
