Abstract:
A method includes forming a source/drain region, and in a vacuum chamber or a vacuum cluster system, preforming a selective deposition to form a metal silicide layer on the source/drain region, and a metal layer on dielectric regions adjacent to the source/drain region. The method further includes selectively etching the metal layer in the vacuum chamber, and selectively forming a metal nitride layer on the metal silicide layer. The selectively forming the metal nitride layer is performed in the vacuum chamber or a vacuum cluster system without vacuum break.

Claim (Index 1):
A method comprising:\n forming a dummy gate stack over a first portion of a semiconductor fin; forming a gate spacer on a sidewall of the dummy gate stack; epitaxially growing a semiconductor material on a second portion of the semiconductor fin; forming a first inter-layer dielectric to cover the semiconductor material; replacing the dummy gate stack with a replacement gate stack; removing the first inter-layer dielectric to re-expose the semiconductor material; in a vacuum chamber, cleaning the semiconductor material; in the vacuum chamber, selectively forming a metal silicide layer on the semiconductor material; and forming a metal silicon nitride layer over the metal silicide layer, wherein at a time the forming the metal silicon nitride layer is finished, a metal of the metal silicide layer does not extend on the gate spacer.
