Abstract:
A method is provided for preparing a semiconductor-on-insulator structure comprising a multilayer dielectric layer.

Claim (Index 15):
A method of preparing a multilayer structure, the method comprising:\n (a) forming a front handle silicon dioxide layer on a front handle surface of a single crystal silicon handle wafer, wherein the single crystal silicon handle wafer comprises two major, generally parallel surfaces, one of which is the front handle surface of the single crystal silicon handle wafer and the other of which is the back handle surface of the single crystal silicon handle wafer, a circumferential edge joining the front handle surface and the back handle surface of the single crystal silicon handle wafer, a central plane between the front handle surface and the back handle surface of the single crystal silicon handle wafer, and a bulk region between the front and back handle surfaces of the single crystal silicon handle wafer; (b) forming a front handle silicon nitride layer on the front handle silicon dioxide layer; (c) annealing the single crystal silicon handle wafer comprising the front handle silicon dioxide layer and the front handle silicon nitride layer at a temperature and duration sufficient to densify the front handle silicon dioxide layer, the front handle silicon nitride layer, or both; and (d) bonding the front handle silicon nitride layer to a donor silicon dioxide layer on a front donor surface of a single crystal silicon donor wafer to thereby form a bonded structure, wherein the single crystal silicon donor wafer comprises two major, generally parallel surfaces, one of which is the front donor surface of the single crystal silicon donor wafer and the other of which is the back donor surface of the single crystal silicon donor wafer, a circumferential edge joining the front donor surface and the back donor surface of the single crystal silicon donor wafer, a central plane between the front donor surface and the back donor surface of the single crystal silicon donor wafer, and a bulk region between the front and back donor surfaces of the single crystal silicon donor wafer, and further wherein the single crystal silicon donor wafer comprises a damage layer formed by ion implantation.
