Patent ID: 6878585

Claim:
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: forming a silicon nitride comprising layer over the first capacitor electrode; after forming the silicon nitride comprising layer, oxidizing the substrate to form a silicon oxide comprising layer over the silicon nitride comprising layer and effective to fill pinholes present in the silicon nitride, at least some of silicon comprised by the silicon oxide being contributed from the first capacitor electrode; and 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.
