Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A device comprising:
a substrate having a first side and an opposing second side and a surface extending from the first side to the second side;
a pixel region disposed within the substrate and operable to sense radiation through the first side of the substrate;
an insulating layer disposed over the second side of the substrate;
a conductive bonding surface disposed within the insulating layer;
an oxide material-containing layer extending along the first side of the substrate, the surface of the substrate and the insulating layer; and
a conductive layer including a first portion and a second portion, the first portion of the conductive layer extending along the surface of the substrate between the first side and the second side of the substrate such that the first portion of the conductive layer is disposed on the surface of the substrate below the first side of the substrate and above the second side of the substrate, the second portion of the conductive layer disposed within the insulating layer and interfacing with the conductive bonding surface such that the second portion forms a conductive bond pad, wherein the second portion of the conductive layer is electrically isolated from the first portion of the conductive layer.
