Abstract

A process for forming a capacitor with a high-k dielectric or ferroelectric layer within a semiconductor device is used to reduce the likelihood of oxidation or materials interactions between that layer and an underlying layer. A first electrode layer includes atoms that form along grain boundaries within the first electrode layer to reduce the oxidation of a conductive plug or undesired materials interactions.
