Patent ID: 7880204

Claim:
A Silicon photodetector, comprising: an insulating substrate having a top surface and a bottom surface; a Silicon layer located on said top surface of said insulator substrate, wherein said Silicon layer contains a center region, with said center region being larger in thickness than the rest of said Silicon layer; a top Silicon dioxide layer that is located on a top surface of said center region; a left wing of said center region, wherein a side portion of said left wing is a left side portion of said center region and a bottom portion of said left wing is a first portion of said Silicon layer that is located to the left of said center region; a right wing of said center region, wherein a side portion of said right wing is a right side portion of said center region and a bottom portion of said right wing is a second portion of said Silicon layer that is located to the right of said center region; and an active region located within said center region, wherein said active region contains a tailored crystal defect-impurity combination and Oxygen atoms, wherein said center region is separated from the rest of said Silicon layer by said left wing and said right wing.
