Abstract: Fin-type transistor fabrication methods and structures are provided having one or more nitrided conformal layers, to improve reliability of the semiconductor device. The method includes, for example, providing at least one material layer disposed, in part, conformally over a fin extending above a substrate, the material layer(s) including a gate dielectric layer; and performing a conformal nitridation process over an exposed surface of the material layer(s), the conformal nitridation process forming an exposed, conformal nitrided surface.
