Abstract:
1. A method of forming a capacitor comprising: forming a first capacitor electrode over a substrate; forming a second capacitor electrode over the substrate; and forming a capacitor dielectric region intermediate the first and second capacitor electrodes, the capacitor dielectric region forming comprising: exposing the silicon oxide comprising layer to an activated nitrogen species generated from a nitrogen-containing plasma effective to introduce nitrogen into at least an outermost portion of the silicon oxide comprising layer, and forming silicon nitride therefrom effective to increase a dielectric constant of the dielectric region from what it was prior to said exposing; and said exposing occurring within a plasma chamber comprising a substrate receiver and a powerable electrode spaced therefrom by at least 0.1 inch, and with the substrate being received by the receiver, and by injecting a nitrogen comprising gas to within the chamber and with the electrode generating said nitrogen-containing plasma.
