Abstract:
A method of producing a semiconductor member, said method comprising:a first step of preparing a first member, the first member having a non-porous layer on a semiconductor substrate to produce an SOI wafer; and a second step of transferring the non-porous layer from the first member onto a second member, wherein reuse of the semiconductor substrate from which the non-porous layer is separated in the second step occurs (nâˆ’1) times, where n is a natural number greater than or equal to 2, wherein the first and second steps are repeated n times to produce n sheets of the SOI wafers at maximum output, wherein after the second step in n-th use, the semiconductor substrate is used to produce a non-SOI wafer, and wherein the n is determined according to a demand for the SOI wafer or a demand for the non-SOI wafer, or based on the inspection results of the semiconductor substrate.
