Patent ID: 7064045

Claim:
A method for forming a patterned silicon bearing material, the method comprising: providing a silicon substrate, the silicon substrate having a surface region and a backside region; forming a plurality of recessed regions on the surface region, each of the plurality of recessed regions having a border region, the plurality of recessed regions forming a patterned surface region; bonding the patterned surface region to a handle surface region of a handle substrate, each of the border regions being bonded to the handle surface region, while each of the recessed regions remain free from attachment to any surface of the handle surface region; applying electromagnetic radiation comprising a laser beam to selected regions on the backside to ablate a thickness of silicon substrate overlying each of the recessed regions; and releasing a thickness of material defined within the recessed region while maintaining each of the border regions bonded to the handle surface region to form a plurality of silicon structures bonded to the handle surface region.
