Patent ID: 7560322

Claim:
A method of making a semiconductor structure, comprising the steps of: providing a silicon carbide wafer; depositing a silicon layer on a surface of said wafer; providing a silicon on insulator structure having a first layer of silicon, an intermediate layer of an oxide of silicon and a third layer of silicon; bonding said third layer of silicon to said deposited silicon layer which is on said surface of said wafer, wherein the step of bonding comprises: polishing said third layer of silicon and polishing said deposited silicon layer which is on said surface of said wafer to a surface roughness of less than around 10 nm, and bringing said polished surfaces of said third layer of silicon and said deposited silicon layer together and applying pressure; removing said first layer of silicon from said silicon on insulator structure; removing said intermediate layer of an oxide of silicon from said silicon on insulator structure to expose said third layer of silicon; and fabricating at least one semiconductor device on said exposed third layer of silicon.
