Patent ID: 8282761

Claim:
A method for simultaneously cutting a compound rod of semiconductor material into a multiplicity of wafers, the method comprising: selecting a first workpiece and a second workpiece from a set of workpieces cut from at least one semiconductor rod, wherein the first and the second workpieces each include two end surfaces; grinding at least one of the two end surfaces of each workpiece so as to create a ground end surface on each workpiece; cementing the ground end surface of the first workpiece to the ground end surface of the second workpiece using a fastener so as to produce a compound rod piece having a longitudinal axis, wherein the fastener is disposed between the workpieces so as create a distance between the workpieces; fixing the compound rod piece in a longitudinal direction on a mounting plate; clamping the plate with the compound rod piece in a wire saw; and cutting the compound rod piece perpendicularly to the longitudinal axis using the wire saw so as to form wafers from each of the first and second workpieces.
