Patent ID: 7622347

Claim:
A method of forming a capacitor, comprising the steps: providing a substrate including a capacitor area isolated by shallow trench isolation structures formed within shallow trench isolation structure trenches; forming an inchoate capacitor on the substrate within the capacitor area whereby portions of the substrate separate the inchoate capacitor from the shallow trench isolation structures; forming a first dielectric layer over the substrate, the shallow trench isolation structures and the inchoate capacitor; patterning the first dielectric layer to: form a patterned first dielectric layer portion masking the inchoate capacitor; and expose at least portions of the shallow trench isolation structures and the substrate portions separating the inchoate capacitor from the shallow trench isolation structures; forming metal portions at least over the substrate portions; forming a second dielectric layer over the patterned first dielectric layer portion, the metal portions and the shallow trench isolation structures whereby the metal portions formed at least over the substrate portions prevent formation of native oxide on at least the substrate portions; and completing formation of the capacitor.
