Patent ID: 8753917

Claim:
A method for fabricating a photoconductor-on-active pixel device, the method comprising: depositing a conductive layer on a first dielectric layer; depositing a first capping layer on the conductive layer; removing portions of the conductive layer and the first capping layer to define a first conductive pad portion and a first interconnect portion, and expose portions of the first dielectric layer; depositing a second dielectric layer on the exposed portions of the first dielectric layer; selectively etching the second dielectric layer with respect to the first capping layer thereby stopping on the first capping layer such that an upper surface of the second dielectric layer is flush with an upper surface of remaining portions of the first capping layer; depositing a second capping layer on the first capping layer and the second dielectric layer; removing portions of the second capping layer to expose portions of the second dielectric layer and removing portions of the second capping layer and first capping layer to expose a portion of the first conductive pad portion; and forming radiation absorbing layers on the exposed portions of the second dielectric layer, the exposed portion of the first conductive pad portion, and the second capping layer.
