ABSTRACT:
A method of slicing an ingot wherein a pre-cut work 3 in which a holding member 2 extending over the entire length of a side surface of a cylindrical ingot 1 is bonded to the side surface of the ingot 1 is set on a slicing apparatus 4, and the pre-cut work 3 is split into a multiplicity of pieces over its longitudinal direction so as to obtain disk-shaped works 5 to be ground, characterized in that a retaining member 2 is used in which a retaining layer 7 which is directly bonded to the side surface of the ingot 1 by a first adhesive agent having an adhesive strength sufficient to receive a rotating force due to a grinding apparatus 6 in a subsequent grinding process, an intermediate layer 8 which is bonded to said retaining layer 7 in a superposed manner by a second adhesive agent whose adhesive strength deteriorates more than that of the first adhesive agent under a fixed condition, and a supporting layer 11 which is connected to said intermediate layer 8 and is connected to a supporting portion 10 of said slicing apparatus 4 are integrally superposed one on top another.
