Patent ID: 8741739

Claim:
A method of forming a silicon-on-insulator (SOI) wafer substrate, the method comprising: forming a high resistivity material layer over a handle substrate, the high resistivity material layer including one of an amorphous silicon carbide (SiC), a polycrystalline SiC, an amorphous carbon, an amorphous diamond, or a polycrystalline diamond; forming an insulator layer over the high resistivity material layer, wherein the insulator layer includes boro-phospho-silicate glass (BPSG); bonding a donor wafer to a top surface of the insulator layer to form the SOI wafer substrate, wherein the donor wafer includes: a donor substrate including a damage layer; and a donor insulator layer contacting the donor substrate and separate from the insulator layer over the high resistivity material layer, wherein the bonding of the donor wafer includes bonding the donor insulator layer to the top surface of the insulator layer, and wherein the bonding includes annealing, causing the donor wafer to cleave at the damage layer; and removing a portion of the donor substrate above the damage layer after the cleaving.
