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.

Abstract: Compositions for removing silicone resins and methods of thinning a substrate by using the same, as well as related methods, apparatus and systems for facilitating the removal of silicone resins are provided. The compositions for removing silicone resins, may include a heterocyclic solvent and an alkyl ammonium fluoride salt represented by a formula, (R)4N+F−, wherein R is a C1 to C4 linear alkyl group. Silicone resins may be effectively removed by using the compositions since the compositions exhibit an excellent decomposition rate with respect to the silicone resins that remain on a semiconductor substrate in a process of backside grinding of the semiconductor substrate, backside electrode formation, or the like.
