Abstract: A semiconductor device and method for fabricating a semiconductor device includes etch selectivity tuning to enlarge epitaxy process windows. Through modification of etching processes and careful selection of materials, improvements in semiconductor device yield and performance can be delivered. Etch selectivity is controlled by using dilute gas, using assistive etch chemicals, controlling a magnitude of bias power used in the etching process, and controlling an amount of passivation gas used in the etching process, among other approaches. A recess is formed in a dummy fin in a region of the semiconductor where epitaxial growth occurs to further enlarge the epitaxy process window.
