Abstract:
Integrated circuitry comprising:a capacitor comprising a first capacitor plate structure, a capacitor dielectric layer and a second capacitor plate structure; a capacitor support structure which at least partially supports the capacitor thereover, the capacitor support structure comprising: conductive material which is in electrical connection with the first capacitor plate structure, the conductive material having a conductive material uppermost surface; and a protuberant structure comprising insulative material at least a portion of which extends elevationally below and outwardly from said conductive material uppermost surface, and over which the first capacitor plate structure is received; and further comprising: an insulative mass which at least partially supports the capacitor structure, the insulative mass having an opening formed therein within which the capacitor support structure is at least partially received, the opening having sidewalls, the protuberant structure being spaced from the sidewalls; and wherein the capacitor dielectric layer does not physically contact the protuberant structure.
