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

Claim (Index 23):
A method of preparing a multilayer structure, the method comprising:\n (a) forming a front donor silicon dioxide layer on a front donor surface of a single crystal silicon donor wafer, 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; (b) forming a front donor silicon nitride layer on the front donor silicon dioxide layer; (c) implanting ions through the front donor silicon nitride layer and the front donor silicon dioxide layer and into the bulk region of the single crystal silicon donor wafer to thereby form a damage layer; and (d) bonding the front donor silicon nitride layer to a 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.
