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

Claim 13:
14. A method for forming a semiconductor device, comprising:
forming an epitaxial source/drain feature having a top surface, a bottom surface, and a side surface connecting the top surface and the bottom surface;
forming a first conductive feature over the top surface of the epitaxial source/drain feature, wherein the first conductive feature is in electrical connection with the epitaxial source/drain feature; and
forming a second conductive feature after forming the first conductive feature, wherein the second conductive feature includes a body portion and a first sidewall portion extending from the body portion, the body portion is below the bottom surface of the epitaxial source/drain feature, and the first sidewall portion is in contact with the first conductive feature.
