Filed: 1988-12-02
Abstract: PURPOSE:To automatically measure a shape in a non-destructive manner according to an optical system in the atmosphere by allowing the focus surface of the optical system to cross a fine pattern at each outer surface position of said pattern. CONSTITUTION:A wafer 12 is placed on a stage 14 and the pattern 10 on the wafer 12 is aimed at by an objective lens 16 inclined by an angle theta to form the image of the pattern 10 on a digital image converter (CCD) 18 by the lens 16. The focus surface of the lens 16 is set above the region to be measured on the pattern 10 and, when the lens 16 is moved to change the position of said focus surface, the region to be measured on the pattern 10 is changed. The pattern 10 is illuminated without changing the positional relation between the lens 16 and the converter 18. The intersecting point (intersecting line) part of the pattern 10 with the focus surface is formed into an image sharply (max. brightness) and the other part is formed into an image in a blurred state (low brightness). Each position of the max. brightness shows the shape of the side surface of the pattern 10 and the shape of the peripheral surface of the pattern 10 can be calculated from the brightness position on each crossing line.
