A method for making a semiconductor device is described. That method comprises forming a dummy dielectric layer that is at least about 10 angstroms thick on a substrate, and forming a sacrificial layer on the dummy dielectric layer. After removing the sacrificial layer and the dummy dielectric layer to generate a trench that is positioned between first and second spacers, a gate dielectric layer is formed on the substrate at the bottom of the trench, and a metal layer is formed on the gate dielectric layer.

A method for making a semiconductor device is described. That method comprises forming a dielectric layer on a substrate, and forming a first metal layer on a first part of the dielectric layer, leaving a second part of the dielectric layer exposed. After a second metal layer is formed on both the first metal layer and the second part of the dielectric layer, a masking layer is formed on the second metal layer.
