    摘要: A conformal doping process for FinFET devices on a semiconductor substrate which includes NFET fins and PFET fins. In a first exemplary embodiment, an N-type dopant composition is conformally deposited over the NFET fins and the PFET fins. The semiconductor substrate is annealed to drive in an N-type dopant from the N-type dopant composition into the NFET fins. A P-type dopant composition is conformally deposited over the NFET fins and the PFET fins. The semiconductor substrate is annealed to drive in a P-type dopant from the P-type dopant composition into the PFET fins. In a second exemplary embodiment, one of the NFETfins and PFET fins may be covered with a first dopant composition and then a second dopant composition may cover both the NFET fins and the PFET fins followed by an anneal to drive in both dopants.
