Method of manufacturing semiconductor device

Abstract

An equipment for manufacturing semiconductor devices is disclosed. This equipment comprises a processing tool for processing a to-be-processed surface of a semiconductor workpiece to a target shape, and a monitor for three-dimensionally monitoring a shape of a processed surface of the semiconductor workpiece while the semiconductor workpiece is set in the processing tool. The monitor radiates the processed surface with incoherent light, divides light reflected from the processed surface, into a plurality of light beams of different wavelengths, acquires a two-dimensional image from each of the divided light beams of different wavelengths, three-dimensionally analyzes the shape of the processed surface, and transmits information on the analysis results to a controller. The controller controls the processing tool in a feedback manner on the basis of the information.
