ALIGNMENT SYSTEM AND METHODS FOR LITHOGRAPHIC SYSTEMS |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide an alignment system for a lithography projecting device, with the accuracy of positioning and/or robust properties improved. <P>SOLUTION: An alignment system for a lithographic apparatus has a source of alignment radiation, a detection system that has a first detector channel and a second detector channel, and a position determining unit that communicates with the detection system. The position-determining unit processes information from the first and second detector channels in combination and determines the position of an alignment mark on a first object relative to a reference position on a second object, based on the combined information. <P>COPYRIGHT: (C)2009,JPO&INPIT |
