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

Claim (Index 1):
A method of preparing a multilayer structure, the method comprising:\n bonding a handle semiconductor oxide layer in interfacial contact with a front surface of a single crystal semiconductor handle substrate to a donor semiconductor nitride layer in interfacial contact with a donor semiconductor oxide layer in interfacial contact with a front surface of a single crystal semiconductor donor substrate to thereby prepare a bonded structure, wherein (i) the single crystal semiconductor donor substrate comprises two major, generally parallel surfaces, one of which is the front surface of the semiconductor donor substrate and the other of which is the back surface of the semiconductor donor substrate, a circumferential edge joining the front and back surfaces of the semiconductor donor substrate, a central plane between the front and back surfaces of the semiconductor donor substrate, and a bulk region between the front and back surfaces of the semiconductor donor substrate, wherein the single crystal semiconductor donor substrate comprises a cleave plane, and (ii) the single crystal semiconductor handle substrate comprises two major, generally parallel surfaces, one of which is the front surface of the single crystal semiconductor handle substrate and the other of which is a back surface of the single crystal semiconductor handle substrate, a circumferential edge joining the front surface and the back surface of the single crystal semiconductor handle substrate, a central plane between the front surface and the back surface of the single crystal semiconductor handle substrate, and a bulk region between the front and back surfaces of the single crystal semiconductor handle substrate, and further wherein the handle semiconductor oxide layer has a wet etch rate ratio greater than 2.
