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

Claim 0:
1. A device, comprising:
a first semiconductor fin and a second semiconductor fin over a substrate;
a source/drain epitaxial structure connected to the first semiconductor fin and the second semiconductor fin, wherein the source/drain epitaxial structure comprises a first protruding portion and a second protruding portion aligned with the first semiconductor fin and the second semiconductor fin, respectively;
a semiconductive cap on and in contact with the first protruding portion and the second protruding portion, wherein a top surface of the semiconductive cap is lower than a top surface of the first protruding portion of the source/drain epitaxial structure; and
a contact in contact with the source/drain epitaxial structure and the semiconductive cap, wherein the semiconductive cap has an inverted triangular cross-sectional profile defined by the first and second protruding portions and the contact.
