Title: Apparatus and method for observing crystal defect
Inventor: MORIYA KAZUO
IPC: G01N21/956
Filed: 1993-11-30
Abstract: PURPOSE:To make possible the observation of a defect of a semiconductor crystal efficiently even in a relatively less intensity of a laser light by setting the wavelength of the laser light based on changes in the intensity of scattering due to the defect with respect to changes in the wavelength of the laser light and changes in absorption coefficient of the laser light in the semiconductor crystal. CONSTITUTION:A laser apparatus is so set to emit a laser light with a wavelength in a range of 960-1010nm. When a focused laser light 5 is made to irradiate a surface 3, scattered light in the direction of 90 deg. out of the scattered light 11 generated by a defect 9 is observed through a cleaved surface. In this case, as the wavelength of the irradiated laser beam 5 is set in a range of 960-1010nm, the incident laser luminous flux and the scattered light 11 within a silicon wafer 1 are not attenuated so much while the image of the defect 9 is observed efficiently because of a large intensity of scattering by the defect 9 thereby making possible the obtaining of an image data even when the defect 9 is very small.
