ABSTRACT:
A method for making a semiconductor device is described. That method comprises forming on a substrate a first gate dielectric layer that has a first substantially vertical component, then forming a first metal layer on the first gate dielectric layer. After forming on the substrate a second gate dielectric layer that has a second substantially vertical component, a second metal layer is formed on the second gate dielectric layer. In this method, a conductor is formed that contacts both the first metal layer and the second metal layer.
