发明名称 METHOD FOR ALIGNMENT BETWEEN MASK AND WORK
摘要 <P>PROBLEM TO BE SOLVED: To prevent a position of a pattern formed on a work by projection exposure from being deviated from a position of a pattern formed by previous exposure processing and a position of a mask pattern for screen printing or the like to be executed in the next step, even in the case of the occurrence of telescopic deformation on the work. <P>SOLUTION: During alignment in a projection exposure device, a scale factor by which a pattern of a mask M is enlarged or reduced is adjusted so as to minimize a value obtained by adding the sum total of amounts of deviation dM between positions of mask marks MAM1 to MAM4 of the mask and reference positions of mask marks SAM1 to SAM4 of a screen mask for use in the next step to the sum total of amounts of deviation dR between mask marks MAM1 to MAM4 of the mask and work marks WAM1 to WAM4, and the mask M or the work W is moved to align the mask M and the work W with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT
