Abstract:
Provided are a method of inspecting a surface and a method of manufacturing a semiconductor device. The methods include preparing a substrate, selecting a spatial resolution of a first optical device by setting a magnification of an imaging optical system, emitting multi-wavelength light toward a first measurement area of the substrate and obtaining first wavelength-specific images, generating first spectrum data based on the first wavelength-specific images, generating first spectrum data of respective pixels based on the first wavelength-specific images, and extracting a spectrum of at least one first inspection area having a range of the first measurement area or less from the first spectrum data, and analyzing the spectrum. The first optical device includes a light source, an objective lens, a detector, and an imaging optical system. The obtaining first wavelength-specific images includes using the imaging optical system and the detector.

Claim (Index 10):
A method of manufacturing a semiconductor device, the method comprising:\n performing a prior manufacturing process on a substrate; and primarily inspecting the substrate using an optical device,\n the optical device including a light source configured to emit light, an objective lens configured to transmit light received from the light source, a detector, and an imaging optical system configured to image light detected by the detector, \n the primarily inspecting the substrate includes selecting a spatial resolution of the optical device by changing a magnification of the imaging optical system, emitting multi-wavelength light toward a measurement area of the substrate using the light source and the objective lens, and obtaining wavelength-specific images, \n generating spectrum data of respective pixels based on the wavelength-specific images, and extracting a spectrum of at least one inspection area having a range of the measurement area or less from the spectrum data, and analyzing the spectrum of the at least one inspection area, performing a subsequent manufacturing process on the substrate after the primarily inspecting of the substrate; determining whether it is necessary to perform inspection on the substrate on which the subsequent manufacturing process is performed; and secondarily inspecting the substrate on which the subsequent manufacturing process is performed in the same method as the primary inspection when it is determined that the inspection is necessary. performing a subsequent manufacturing process on the substrate after the primarily inspecting of the substrate; determining whether it is necessary to perform inspection on the substrate on which the subsequent manufacturing process is performed; secondarily inspecting the substrate on which the subsequent manufacturing process is performed in response to determining that the inspection is necessary, the secondarily inspecting the substrate being performed using the same method as the primarily inspecting the substrate; and after the secondary inspection, measuring a structural change of the inspection area by the subsequent manufacturing process by comparing the obtained wavelength-specific images of the substrate on which the prior manufacturing process is performed to obtained wavelength-specific images of the substrate on which the subsequent manufacturing process is performed, wherein an inspection area in the secondary inspection is the same as the inspection area in the primary inspection.
