SYSTEMS AND METHODS FOR MEASURING DISTANCE OF SEMICONDUCTOR PATTERNS

A system and method of measuring a distance of semiconductor patterns is provided. The system includes a microscope and a control unit. The control unit calculates standard coordinates of standard points in view-fields that include spots, spot coordinates of spots with respect to standard points, real coordinates of spots from both of the standard coordinates and spot coordinates, and finally the distance between the two spots from the first and second real coordinates. Coordinates are determined using high magnification, in conjunction with pixel counting, allowing more precise distance measurements.
