Abstract:
Integrated circuitry, comprising:a first capacitor electrode layer received over a substrate, the first capacitor electrode layer having opposing lateral edges; a capacitor dielectric layer received over the first capacitor electrode layer, the capacitor dielectric layer comprising an edge terminus; a second capacitor electrode layer received over the capacitor dielectric layer; the second capacitor electrode layer having opposing lateral edges; the first capacitor electrode layer, the capacitor dielectric layer and the second capacitor electrode layer comprising a capacitor; the capacitor dielectric layer edge terminus being laterally coincident with at least a portion of one of the opposing lateral edges of the second capacitor electrode layer; and an insulative silicon nitride comprising cap received over the capacitor dielectric layer edge terminus and the one opposing lateral edge of the second capacitor electrode layer, the cap not contacting any portion of the opposing lateral edges of the first capacitor electrode layer.
