Claim Text:
1. A method for fabricating a pixel, the method comprising: implanting a dopant in a substrate to form an active region, wherein the dopant is deposited pursuant to forming a semiconductor element of the pixel; forming a first polysilicon layer over the active region; forming a buried contact structure proximate the active region to provide a conductive path between the first polysilicon layer and the active region, wherein said forming a buried contact structure includes: forming an insulating layer between the first polysilicon layer and the active region; and breaking down at least a portion of the insulating layer in the active region through the first polysilicon layer to provide electrical contact between the active region and the first polysilicon layer, wherein said breaking down comprises breaking down at least a portion of the insulating layer using a process including ion implantation; and forming a second polysilicon layer in electrical contact with the first polysilicon layer, wherein:
