A method of evaluating a semiconductor wafer, which has a polished surface, by using a laser surface-inspection device including light-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 light-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.

The invention disclosed herein generally relates to wideband resonant polarizers that require extremely small amounts of matter in their embodiments. These polarizers can be made with dielectric materials such that light and other electromagnetic waves interacting with them suffer essentially no absorptive loss. This new class of polarizers is fashioned with dielectric or semiconductor nano/microwire grids that are mostly empty space if surrounded by air or vacuum. It is fundamentally and practically extremely significant that the wideband spectral expressions presented herein can be generated in these minimal systems. These ultra-sparse polarizers are useful in various spectral regions for numerous useful applications.
