ABSTRACT:
Methods and structures to reduce optical crosstalk in solid state imager arrays. Sections of pixel material layers that previously would have been etched away and disposed of as waste during fabrication are left as conserved sections. These conserved sections are used to amend the properties and performance of the imager array. In the resulting structure, the conserved sections absorb incident light. The patterned portions of conserved material provide additional light shielding for array pixels.
