Abstract:
Approaches for enabling uniform epitaxial (epi) growth in an epi junction area of a semiconductor device (e.g., a fin field effect transistor device) are provided. Specifically, a semiconductor device is provided including a dummy gate and a set of fin field effect transistors (FinFETs) formed over a substrate; a spacer layer formed over the dummy gate and each of the set of FinFETs; and an epi material formed within a set of recesses in the substrate, the set of recesses formed prior to removal of an epi block layer over the dummy gate.
