Abstract:
A peeling apparatus includes an ingot holding unit holding an ingot in a hanging state where a portion of the ingot to be peeled off as the wafer is directed downwardly, a water container containing water therein, an ultrasonic unit immersed in the water in the water container, a moving unit moving the ingot holding unit vertically into a position where the ingot holding unit faces the ultrasonic unit and at least the portion of the ingot to be peeled off as the wafer is immersed in the water in the water container, and a nozzle ejecting water to the portion of the ingot to be peeled off as the wafer thereby to promote the peeling of the wafer from the ingot.

Claim (Index 3):
The peeling apparatus according to  claim 1 , wherein\n the ingot includes a single-crystal SiC ingot having a c-axis and a c-plane perpendicular to the c-axis, and the peel-off layer is made up of modified regions where SiC is separated into Si and C in the ingot and a succession of cracks extending isotropically along the c-plane from the modified regions, by applying a laser beam that is transmittable through single-crystal SiC to the ingot while a focal point of the laser beam is being positioned at a depth which corresponds to the thickness of the wafer, in the ingot from an end face of the ingot.
