Patent ID: 10483377

Abstract:
Devices and methods of growing unmerged epitaxy for fin field-effect transistor (FinFet) devices are provided. One method includes, for instance: obtaining a wafer having at least one source, at least one drain, and at least one fin; etching to expose at least a portion of the at least one fin; forming at least one sacrificial gate structure; and forming a first layer of an epitaxial growth on the at least one fin. One device includes, for instance: a wafer having at least one source, at least one drain, and at least one fin; a first layer of an epitaxial growth on the at least one fin; at least one second layer of an epitaxial growth superimposing the first layer of an epitaxial growth; and a first contact region over the at least one source and a second contact region over the at least one drain.
