Abstract:
An equipment for manufacturing semiconductor devices, comprising:a processing tool which processes a to-be-processed surface of a semiconductor workpiece to a target shape; a monitor which three-dimensionally monitors a shape of a processed surface of the semiconductor workpiece while the semiconductor workpiece is set in the processing tool; and a controller which controls the processing tool in a feedback manner on the basis of the shape of the processed surface monitored by the monitor, wherein the monitor includes: a light source radiating the processed surface with incoherent light; a spectroscope which divides light reflected from the processed surface, into a plurality of light beams of different wavelengths; an area image sensor which acquires a two-dimensional image from each of the divided light beams of different wavelengths; and a data processing tool which three-dimensionally analyzes the shape of the processed surface, and transmits information on analysis results to the controller.
