Abstract

A method of making an on-die decoupling capacitor for a semiconductor device is described. That method comprises forming a first barrier layer on a conductive layer. The upper surface of the first barrier layer is modified to enable a dielectric layer with an acceptable nucleation density to be formed on the first barrier layer. A dielectric layer is formed on the first barrier layer, and a second barrier layer is formed on the dielectric layer.
