Abstract:
A method of evaluating a semiconductor wafer, which has a polished surface, by using a laser surface-inspection device including incident and light-receiving systems, includes evaluating the semiconductor wafer by detecting, as a light point defect, an abnormality of a process-induced defect and a surface-adhered foreign matter present on the polished surface of the semiconductor wafer, on the basis of measurement result obtained by directing incident light to the polished surface of the semiconductor wafer from one incident system and receiving, with a first light-receiving system, radiation light which has been radiated by the incident light being reflected or scattered by the polished surface, measurement result obtained by receiving the radiation light with a second light-receiving system, and measurement result obtained by receiving the radiation light with a third light-receiving system, and at least one of a light-receiving angle and polarization selectivity differs among the first, second and third light-receiving systems.

Claim (Index 8):
The method of evaluating according to  claim 1 ,\n wherein the incident angle of the incident light is higher than 0\u00b0 and less than 90\u00b0 when all directions horizontal to the polished surface of the semiconductor wafer are defined as 0\u00b0 and a direction perpendicular to the polished surface as 90\u00b0.
