Abstract: A monitoring system for manufacturing a semiconductor device comprises a source module, an optical module including a collector collecting and reflecting extreme ultraviolet generated light from the source module, an illumination optical system including a field facet mirror, and a projection optical system transferring the extreme ultraviolet light reflected from a reticle to a substrate. A calculating module calculates a degradation rate of the optical module, and a method comprises respectively generating a reference image profile and an (N)th image profile through the second sensor module by correcting the far field image of the extreme ultraviolet with respect to the intensity of the extreme ultraviolet at a reference time point and an (N)th time point after the reference time point, and calculating the degradation rate of the optical module by using a ratio of the reference image profile and the (N)th image profile by the calculation module.

Abstract: A monitoring unit for measuring, in real time, the power of an EUV beam transmitted to a substrate and a substrate treating apparatus including the monitoring unit. The substrate treating apparatus comprising a source which generates an EUV beam, a scanner which transfers a mask pattern to a substrate by using the EUV beam, and a monitoring unit which comprises a detector for detecting the EUV beam and monitoring the power of the EUV beam in real time, wherein the detector is disposed on a path along which the EUV beam passes through a first mirror assembly provided in the scanner and moves to a reticle on which the mask pattern is formed.
