发明名称 Method for enhancing the measuring accuracy when determining the coordinates of structures on a substrate
摘要 A method for the high-precision measurement of coordinates on a substrate is disclosed. The substrate is placed on a stage moveable in X/Y coordinate directions. First, a plurality of images of a structure on a substrate are imaged by means of a 2-dimensional detector during the relative movement of a measuring objective in Z coordinate direction and the simultaneous movement of the stage in X and Y coordinate directions.
