PROBLEM TO BE SOLVED: To provide a silicon wafer peeling method capable of easily and efficiently peeling off the silicon wafer by solving a problem of a conventional silicon wafer peeling method in which the silicon wafer is peeled off sheet by sheet from a beam member while blowing hot air in the air without rough washing.SOLUTION: The silicon wafer peeling device comprises: a heat insulating material 3 that supports a beam member 2 bearing plural silicon wafers adhered via adhesive; an induction heating coil 5 that heats the beam member 2; a feed mechanism 4 that feeds the heat insulating material 3 relative to the induction heating coil 5 in a horizontal direction; a suction pad 6 that peels off the silicon wafer sheet by sheet; and a water tank 7 for soaking the silicon wafer, the beam member 2 and the heat insulating material 3 in a liquid.

PROBLEM TO BE SOLVED: To provide a wafer manufacturing method and a wafer manufacturing apparatus which separate wafers, formed by slicing ingots, one by one and easily and evenly clean front and rear surfaces of each wafer.SOLUTION: Wafers W, each of which is formed by slicing an ingot adhered to a support base with an adhesive into a strip like shape with a part of the support base included therein, are separated at the parts of the support bases one by one by a separation unit 2, and front and rear surfaces of the separated wafers W are cleaned one by one by a cleaning unit 3. Each wafer W is immersed in a peeling tank 5 to remove a cutting piece of the support base and the adhesive from the wafer W.
