Patent ID: 8395243

Claim:
A silicon device, comprising: a silicon wafer bounded by a first surface and a second opposite said first surface, said silicon wafer having a device fabricated on one of said first surface and said second surface; said silicon wafer having a doping profile situated adjacent at least one of said first surface and said second surface, said doping profile having a plurality M of doped layers; each of plurality M of doped layers having a thickness of less than 10 Angstroms, and a dopant sheet density at least 10 14 cm −2 , where M is an integer greater than 1; said plurality M of doped layers separated from each other by M−1 interleaved layers of silicon, at least one of said M−1 interleaved layers of silicon having a thickness in the range of 10 Angstroms to 30 Angstroms; said silicon wafer having at least one of said first surface and said second surface electronically passivated irrespective of a density of defects present on said respective one of first surface and said second surface.
