Patent ID: 11935941
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A semiconductor structure, comprising:
an epitaxial region over a substrate;
a first insulation layer over the epitaxial region and the substrate;
a gate structure over the substrate, wherein the gate structure includes a centerline defined in a first cross-sectional view;
a spacer element disposed on sidewalls of the gate structure, wherein the spacer element is SiOCN;
a first contact extending through the first insulation layer to interface a top surface of the gate structure and a top surface of the spacer element, wherein the first contact has a centerline defined in the first cross-sectional view that is displaced a first shift distance from the centerline of the gate structure, and wherein the first contact includes a sidewall extending from a first terminal end to a second terminal end and a recap layer disposed on a middle region of the sidewall, wherein a first end region adjacent the first terminal end and a second end region adjacent the second terminal end are free of the recap layer; and
a second contact over and extending towards the epitaxial region.
