Patent ID: 8124499

Claim:
A method for fabricating a 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 energetic 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; subjecting the semiconductor substrate to a treatment process; subjecting the surface region of the semiconductor substrate to a second plurality of energetic particles generated using the linear accelerator, the second plurality of energetic 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, wherein the second temperature is higher than the first temperature and greater than 350 Degrees Celsius; and freeing the thickness of material to be detached using a cleaving process, wherein a surface of the material to be detached that faces away from a remaining portion of the semiconductor substrate is not bonded to a support member during the cleaving process.
