Patent ID: 11901396
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A device comprising:
a semiconductor substrate having a front side and an opposing back side and a surface extending from the front side to the back side;
a pixel region disposed within the semiconductor substrate;
an insulating layer extending from the front side of the substrate;
a conductive bonding surface disposed within the insulating layer;
an oxide material-containing layer interfacing with the back side and the surface of the semiconductor substrate; 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 semiconductor substrate between the front side and the back side of the substrate such that the first portion of the conductive layer is disposed on the surface of the substrate below the front side of the substrate and above the back 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, the conductive bond pad having opposing sidewall surfaces that interface with the insulating layer, wherein the second portion of the conductive layer is electrically isolated from the first portion of the conductive layer.
