Abstract: A semiconductor wafer including a main body including first and second surfaces opposite each other, a notch including a recess on an outer periphery, a first bevel region formed along the outer periphery of the main body, including a first slope connecting the first and second surfaces and having a first height with respect to a straight line extending from a first point where the first surface and the first slope meet to a second point where the second surface and the first slope meet, and a second bevel region in contact with the recess or opening, including a second slope connecting the first and second surfaces and having a second height, different from the first height, with respect to a straight line extending from a third point where the first surface and the second slope meet to a fourth point where the second surface and the second slope meet.
