Abstract
A method for forming a salicide includes epitaxially growing source/drain (S/D) regions on a semiconductor fin wherein the S/D regions include (111) facets in a diamond shape and the S/D regions on adjacent fins have separated diamond shapes. A metal is deposited on the (111) facets. A thermally stabilizing anneal process is performed to anneal the metal on the S/D regions to form a silicide on the (111) facets. A dielectric layer is formed over the S/D regions. The dielectric layer is opened up to expose the silicide and to form contact holes. Contacts to the silicide are formed in the contact holes.
