Abstract:
A high resistivity single crystal semiconductor handle structure for use in the manufacture of SOI structure is provided. The handle structure comprises an intermediate semiconductor layer between the handle substrate and the buried oxide layer. The intermediate semiconductor layer comprises a polycrystalline, amorphous, nanocrystalline, or monocrystalline structure and comprises a material selected from the group consisting of Si 1-x Ge x , Si 1-x C x , Si 1-x-y Ge x Sn y , Si 1-x-y-z Ge x Sn y C z , Ge 1-x Sn x , group IIIA-nitrides, semiconductor oxides, and any combination thereof.

Claim (Index 41):
A method of preparing a silicon-on-insulator structure, the method comprising:\n bonding an exposed front surface layer of a single crystal semiconductor handle structure and an exposed oxidized front surface of a single crystal silicon donor wafer; wherein the single crystal semiconductor handle structure comprises (a) a single crystal silicon wafer handle substrate comprising two major, generally parallel surfaces, one of which is a front surface of the single crystal silicon wafer handle substrate and the other of which is a back surface of the single crystal silicon wafer handle substrate, a circumferential edge joining the front and back surfaces of the single crystal silicon wafer handle substrate, and a central plane of the single crystal silicon wafer handle substrate between the front and back surfaces of the single crystal silicon wafer handle substrate, wherein the single crystal silicon wafer handle substrate comprises a p-type dopant and has a bulk resistivity between about 750 ohm cm and about 100,000 Ohm-cm; (b) an intermediate semiconductor layer having electron affinity lower than that of the single crystal silicon wafer handle substrate, wherein the intermediate semiconductor layer comprises a polycrystalline, amorphous, nanocrystalline, or monocrystalline structure and comprising a material selected from the group consisting of Si 1-x C x  wherein x is a molar ratio with a value between 0.1 and 0.9, a group IIIA-nitride, a metal oxide, and any combination thereof; and wherein the single crystal silicon donor wafer comprises two major, generally parallel surfaces, one of which is the exposed oxidized front surface of the single crystal silicon donor wafer and the other of which is a back surface of the single crystal silicon donor wafer, a circumferential edge joining the front and back surfaces of the single crystal silicon donor wafer, and a central plane of the single crystal silicon donor wafer between the front and back surfaces of the single crystal silicon donor wafer, wherein the single crystal silicon donor wafer comprises a cleave plane.
