Patent ID: 7943485

Claim:
A method for preparation of thin semiconductor film, comprising the steps of: providing a semiconductor wafer with a first surface and second surface; disposing a nucleation layer on said first surface, said nucleation layer having a first surface and a second surface, said second surface of said nucleation layer being proximal to said semiconductor wafer; disposing a first layer of synthetic diamond on top of said nucleation layer, said first layer of synthetic diamond having a first surface and a second surface, said second surface of said first layer of synthetic diamond being proximal to said semiconductor wafer; implanting ions into said semiconductor wafer through said nucleation layer and said first layer of synthetic diamond to create in the volume of said semiconductor wafer at a depth close to the average penetration depth of said ions, a layer of damage; said layer of damage defining a film region and a bulk region in said semiconductor wafer, said film region being disposed between said layer of damage and said nucleation layer, said bulk region disposed between said layer of damage and said second surface of said semiconductor wafer; depositing a second layer of synthetic diamond on said first layer of synthetic diamond; separating said film region from said bulk region of said semiconductor wafer.
