IPC: H01L21/027
Filed: 1981-06-19
Abstract: PURPOSE:To obtain correct coordinates, by estimating each mirror curvature in X and Y directions, establishing corrective oblique coordinates against the curvature thereafter, calculating cross coordinates against the oblique coordinates, and relating both coordinates. CONSTITUTION:Three cross patterns 6 are aligned in X-direction at center of measurement 5. There exists a curvature DELTA in the patterns 6 of the measurement 5. As there exists a curvature delta in a mirror 4, the results of measurement show a curvature of delta-DELTA. And, when the measurement 5 is rotated by 180 deg. and mounted, the curvature of patterns 6 of the measurement 5 becomes DELTA in reverse direction. The results of measurement show that of delta+DELTA. Two-fold of the mirror curvature delta can be calculated as a parameter of distance from an origin of coordination, by putting these measurement data together. Oblique coordinates are made after correcting the curvatures deltax(y) and deltay(x). As they have a right angle error theta against cross coordinates, the error is calculated through both coordinates and theta.
