Abstract:
1. A method of forming conductive interconnects in an imager pixel comprising multilevel metal routing layers, comprising: forming a node of a circuit component of an imager pixel on a substrate; forming a conductive metal line at a first metal routing level that is elevationally outward of the circuit component of the imager pixel; depositing insulative material above the first metal routing level over the conductive metal line and over the circuit component of the imager pixel; in a common masking step, etching a first opening through the insulative material to the conductive metal line and etching a second opening through the insulative material to the node of the circuit component of the imager pixel that is received elevationally inward of the conductive metal line; concurrently depositing conductive material to within the first and second openings in respective conductive connection with the conductive metal line and with the node of the circuit component of the imager pixel; and forming a first metal line at a second metal routing level that is above the first metal routing level in conductive connection with the conductive material in the first opening and forming a second metal line at the second metal routing level in conductive connection with the conductive material in the second opening.
