Patent ID: 7872742

Claim:
A substrate inspection apparatus comprising: a moving device which moves said substrate; an illumination device which irradiates said substrate with a first light; a detection device which detects a second light generated from said substrate due to irradiation with said first light; and a first processing system which evaluates said substrate based on said detected second light, wherein the detection device includes a plurality of first reflecting units arranged at a plurality of azimuth angles, respectively, with respect to said substrate, a plurality of second reflecting units arranged at higher angle of elevation than said plurality of first reflecting units with respect to said substrate, and at positions corresponding to said plurality of azimuth angles, and a plurality of detection units arranged at positions corresponding to the positions of said plurality of second reflecting units, the plurality of detection units detecting light reflected from said plurality of second reflecting units, and wherein said plurality of first reflecting units define a first rotational paraboloid surface, and said plurality of second reflecting units define a second rotational paraboloid surface.
