Patent ID: 11915977
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. A device, comprising:
an application-specific integrated circuit (ASIC) device that includes:
a second substrate;
a second intermetal dielectric (IMD);
a second conductive element embedded within the second IMD;
a first segment of an interconnect-plug that is electrically coupled to the second conductive element and that extends partially through the second IMD; and

an image sensor device bonded to the ASIC device, wherein the image sensor device includes:
a first substrate;
a first IMD;
a first conductive element embedded within the first IMD; and
a second segment of the interconnect-plug that is electrically coupled to the first conductive element and that extends completely through the first IMD, wherein the second segment of the interconnect-plug is wider than the first segment of the interconnect-plug, and wherein a vertical elevation corresponding to where the second segment meets the first segment is located between a topmost surface and a bottommost surface of the first conductive element.
