发明名称 Reticle, pattern transferred thereby, and correction method
摘要 A reticle that allows deviation in rotation and magnification of an exposure region detected just using a wafer subjected to exposure and development without having to provide an underlying pattern, a pattern transferred using such a reticle, and a correction method are achieved. A first measurement pattern is provided on a dicing line pattern of the X axis direction. Also, a second measurement pattern is formed on a line of extension of the first measurement pattern in the Y axis direction. Similarly, a third measurement pattern is formed on the dicing line pattern in the Y axis direction. A fourth measurement pattern is provided corresponding to the third measurement pattern.
