Abstract

A focal plane array, comprised of an infrared (IR) photovoltaic detector array coupled to a charge coupled device (CCD), which provides for minimum deviation in input threshold voltage between individual detector input nodes of the array is disclosed. In one embodiment, an oxide nitride dielectric layer overlays the entire CCD with the exception of the areas beneath the direct injection gates where only a thin oxide dielectric is formed. In another embodiment, the oxide beneath the direct injection gates is substantially thinner than the oxide beneath the remainder of the CCD structure.
