Patent ID: 7910458

Claim:
A method for fabricating free standing thickness of materials using one or more semiconductor substrates, comprising: providing a semiconductor substrate having a surface region and a thickness; subjecting the surface region of the semiconductor substrate to a first plurality of high energy particles generated using a linear accelerator to form a region of a plurality of gettering sites within a cleave region, the cleave region being provided beneath the surface region to define a thickness of material to be detached, the semiconductor substrate being maintained at a first temperature, the first plurality of high energy particles being provided at a first implant angle; subjecting the semiconductor substrate to a treatment process; subjecting the surface region of the semiconductor substrate to a second plurality of high energy particles generated using the linear accelerator, the second plurality of high energy particles being provided to increase a stress level of the cleave region from a first stress level to a second stress level, the semiconductor substrate being maintained at a second temperature, the second plurality of particles being provided at a second implant angle different from the first implant angle; and freeing the thickness of detachable material using a cleaving process.
