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

Claim 14:
15. An integrated circuit (IC) structure comprising:
a gate structure;
a first epitaxial structure on a first side of the gate structure;
a second epitaxial structure on a second side of the gate structure;
a front-side interconnection structure on a front-side of the first epitaxial structure and a front-side of the second epitaxial structure;
a backside dielectric layer, wherein the gate structure, the first epitaxial structure, and the second epitaxial structure are between the backside dielectric layer and the front-side interconnection structure; and
a backside via extending through the backside dielectric layer, the backside via being electrically connected to the first epitaxial structure, wherein the backside dielectric layer extends continuously from the backside via to under the second epitaxial structure.
