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

Claim 0:
1. A device, comprising:
a second substrate;
a second dielectric layer disposed over the second substrate;
a first dielectric layer disposed over the second dielectric layer;
a first substrate disposed over the first dielectric layer;
a second conductive element embedded in the second dielectric layer;
a first conductive element embedded in the first dielectric layer; and
an interconnect-plug disposed on the second conductive element, wherein the interconnect-plug extends through the first dielectric layer, through the first conductive element, and partially through the second dielectric layer, wherein the interconnect-plug includes a second segment and a first segment that is wider than the second segment, and wherein the second segment and the first segment meet at a point having an elevation that is between a topmost surface and a bottommost surface of the first conductive element.
