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 6):
The method of evaluating according to  claim 5 ,\n which comprises performing the determination according to the following criteria: TABLE 1 Types of abnormalities Determination criteria Surface-adhered detected only in measurement result 2, and not foreign matter detected in measurement result 1 and measurement result 3, satisfies (detection size in measurement result 3)/(detection size in measurement result 2) < X, or satisfies (detection size in measurement result 1)/(detection size in measurement result 2) < X Process-induced detected in at least one of measurement result 1 and defect measurement result 3, and not detected in measurement result 2, satisfies (detection size in measurement result 3)/(detection size in measurement result 2) \u2265 X, or satisfies (detection size in measurement result 1)/(detection size in measurement result 2) \u2265 X wherein 1.0 < X < 2.0 is satisfied.
