Buried conductor for imagers
摘要:
A pixel cell having a photo-conversion device at a surface of a substrate and at least one contact area from which charge or a signal is output or received. A first insulating layer is located over the photo-conversion device and the at least one contact area. The pixel cell further includes at least one conductor in contact with the at least one contact area. The conductor includes a polysilicon material extending through the first insulating layer and in contact with the at least one contact area. Further, a conductive material, which includes at least one of a silicide and a refractory metal, can be over and in contact with the polysilicon material.
