Abstract

A method for fabricating a semiconductor-based device includes providing a substrate including a semiconductor layer, forming a gate dielectric layer on the semiconductor layer, forming a plasma including deuterium, plasma implanting deuterium from the plasma into the substrate, and annealing the substrate to promote passivation of the interface between the dielectric layer and the semiconductor layer.
