摘要： A workpiece size measurement method suitable for length measurement of multilayered circuit elements with increased complexities is disclosed. This method employs a technique for changing measurement conditions in a way pursuant to either an image of workpiece or the situation of a target semiconductor circuit element to be measured when measuring pattern sizes on the workpiece image using design data of the semiconductor circuit element. With such an arrangement, adequate measurement conditions are selectable in accordance with the state of workpiece image and/or the state of a circuit element formed on the workpiece, thereby making it possible to improve the measurement efficiency. A workpiece size measurement apparatus using the technique is also disclosed.

摘要： One of principal objects of the present invention is to provide a sample dimension measuring method for detecting the position of an edge of a two-dimensional pattern constantly with the same accuracy irrespective of the direction of the edge and a sample dimension measuring apparatus. According to this invention, to accomplish the above object, it is proposed to correct the change of a signal waveform of secondary electrons which depends on the direction of scanning of an electron beam relative to the direction of a pattern edge of an inspection objective pattern. It is proposed that when changing the scanning direction of the electron beam in compliance with the direction of a pattern to be measured, errors in the scanning direction and the scanning position are corrected. In this configuration, a sufficient accuracy of edge detection can be obtained irrespective of the scanning direction of the electron beam.
