Patent ID: 8492193

Claim:
A method for producing a solid-state image sensing device, comprising: growing an epitaxial layer of silicon on a silicon substrate produced from a single silicon crystal containing solid-soluted carbon at a concentration of 3×10 16 -8×10 16 atoms/cm 3 and solid-soluted oxygen at a concentration of 1.4×10 18 -1.6×10 18 atoms/cm 3 ; optionally growing an oxide film and a nitride layer on the epitaxial layer: subjecting the resulting silicon substrate to device production processes including a low temperature heat treatment of 600° C. to 700° C. such that carbon-oxygen based precipitates having a size in the range of 75 nm to 180 nm (inclusive of 75 nm and 180 nm) are existent in the silicon substrate at a density of 1×10 7 -1×10 8 precipitates/cm 2 , thereby forming a gettering sink in a region close to the epitaxial layer.
