Abstract:
1. A three-dimensional micropattern profile measuring system comprising: a first measuring mechanism emitting an electron beam; a second measuring mechanism emitting a light beam; a storage unit for storing heights of a plurality of patterns formed in a test pattern place in a scribe line area of a wafer formed to divide the wafer into a plurality of semiconductor devices, said heights being obtained by irradiating the plurality of patterns with the light beam, and widths and contrasts of the plurality of patterns obtained by irradiating the plurality of patterns with the electron beam; and a calculation unit for calculating correlations among the obtained height, width and contrast of each of the plurality of patterns, and determining the height of a pattern in a semiconductor device from the width and contrast obtained by irradiating the pattern with the electron beam and from each of said correlations.
