Abstract

A method to implant dopants onto fin-type field-effect-transistor (FINFET) fin surfaces with uniform concentration and depth levels of the dopants and the resulting device are disclosed. Embodiments include a method for pulsing a dopant perpendicular to an upper surface of a substrate, forming an implantation beam pulse; applying an electric or a magnetic field to the implantation beam pulse to effectuate a curvilinear trajectory path of the implantation beam pulse; and implanting the dopant onto a sidewall surface of a target FINFET fin on the upper surface of the substrate via the curvilinear trajectory path of the implantation beam pulse.
