Claim 0:
1. A method of evaluating a silicon wafer, which comprises:
a first determination that determines presence of a linear defect, having a size equal to or greater than a detection limit of the first determination, in a first region and determines the absence of a linear defect, having a size equal to or greater than a detection limit of the first determination, within a second region of the surface of the evaluation-target silicon wafer by inspecting a surface of an evaluation-target silicon wafer with a light scattering type surface inspection device; and
a second determination that determines presence or absence of another linear defect, having a size below a detection limit of the first determination, through observing, with an atomic force microscope, within a part of or a whole of the second region of the surface of the evaluation-target silicon wafer.
