ABSTRACT:
A slicing apparatus is disclosed which slices a cylindrical ingot into disc-shaped wafers by a rotating blade. The slicing apparatus includes an ingot support device which is used to contact support the ingot at a position opposed to the position of the ingot to be sliced by the blade. Therefore, a rection force which is produced in the ingot slicing can be supported by the ingot support device, thereby eliminating any ill effects on the hold surface of the ingot.
