Abstract:
A wafer is produced from a compound single crystal ingot having end surface. A separation plane is formed by setting the focal point of a laser beam inside the ingot at a predetermined depth from the end surface. The depth corresponds to the thickness of the wafer to be produced. The laser beam is applied to the end surface to form a modified layer parallel to the end surface and cracks extending from the modified layer, thus forming the separation plane. The ingot has first atoms having a larger atomic weight and second atoms having a smaller atomic weight, and the end surface of the ingot is set as a polar plane where the second atoms are arranged in forming the separation plane. After producing the wafer from the ingot, the first end surface is ground to be flattened.

Claim (Index 2):
The wafer producing method according to  claim 1 , wherein the compound single crystal ingot is a GaN ingot, and the first end surface is set as a polar plane where nitrogen (N) atoms are arranged.
