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

Claim 0:
1. A semiconductor structure comprising:
a first conductive structure disposed within a first layer of the semiconductor structure;
a dielectric structure disposed within a second layer of the semiconductor structure, the second layer being disposed on the first layer, wherein the dielectric structure comprises one or more of:
a barrier layer on a bottom surface of the dielectric structure,
a redistribution oxide layer, or
a bonding dielectric layer on a top surface of the dielectric structure;

a second conductive structure disposed within a recessed portion of the dielectric structure that extends to the first conductive structure, the second conductive structure having a concave recessed portion on a top surface of the second conductive structure; and
multiple layers of conductive material disposed within the concave recessed portion of the second conductive structure.
