Classification: CPC H | IPC H

Claim 12:
13. A semiconductor structure comprising:
a first wafer comprising:
a first dielectric structure that includes a first recessed portion;
a first conductive structure disposed within the first recessed portion, the first conductive structure including a first concave recessed portion on a top surface of the first conductive structure; and
a first conductive material disposed within the first concave recessed portion of the first conductive structure; and

a second wafer comprising:
a second dielectric structure that includes a second recessed portion, the second dielectric structure being bonded to the first dielectric structure;
a second conductive structure disposed within the second recessed portion, the second conductive structure including a second concave recessed portion on a top surface of the second conductive structure; and

a second conductive material disposed within the second concave recessed portion, the second conductive material being bonded to the first conductive material, wherein one or more of the first conductive material or the second conductive material comprises one or more of:
a 2-dimensional layered material, or
a metal nitride material.
