Title: Method and apparatus for detecting position
Inventor: TANAKA HIROSHI
IPC: G03F9/00
Filed: 2003-02-21
Abstract: <P>PROBLEM TO BE SOLVED: To improve mark detection rate of a semiconductor manufacturing apparatus.  <P>SOLUTION: The appearance of especially prealignment mark on a wafer varies according to the increased density of a semiconductor. This is caused by the change of the line thickness due to the lamination structure of a part and is also caused by the change of brightness due to the variation in the reflectivity of the mark. Even with an image like that, the edge and its direction of a mark are simultaneously extracted to improve the detection rate, and matching is performed with a template stored in advance, comprising feature interested points which are interested in an edge for each edge direction, for optimization based on automatic deformation of the template corresponding to deformation of the mark and change in brightness of the mark. The optimized template is self-learned so that it is used for matching at the next time on. Thus, the detection modulus of the mark is improved.  <P>COPYRIGHT: (C)2004,JPO
