Granted: 2001-04-11
Abstract: To provide an apparatus and method for measuring the flaw density and flaw scattering capacity of a semiconductor effective for the accurate evaluation of a crystal flaw. The present invention is characterized in that tt is supposed that flaws 14 present in a semiconductor 12 have the same size and the intensity of scattering light 16 measured by the scanning of laser beam 10 is adapted to the attenuation curve of the laser beam 10 to determine the presence depth (delta) of each of the flaws 14. By this constitution, the difference between the scattering capacities of the respective flaws 14 is expressed as the difference between the presence depths (delta) of the flaws 14. As a result, even when flaws different in sizes are distributed, accurate flaw density can be obtained. In an example, a laser 10 is irradiated on the surface of a semiconductor wafer 32 while a stage 34 mounted on the semiconductor wafer 32 is moved, and scattering lights 16 emitted from the surface of the semiconductor wafer 32 is received by the receiving device 26, and an intensity distribution of the scattering lights 16 is measured. The intensity distribution is processed by the controller 20 so as to obtain a defect density of the semiconductor wafer 32.
