Abstract: A capacitor includes an elevationally inner capacitor electrode, an elevationally outer capacitor electrode, and capacitor insulator between the elevationally inner and outer capacitor electrodes. The elevationally inner capacitor electrode comprises a hollow longitudinally-elongated conductive cylinder-like portion and a non-hollow longitudinally-elongated conductive cylinder-like portion electrically coupled with the hollow cylinder-like portion. The non-hollow cylinder-like portion is radially of and extends longitudinally along a longitudinal side surface of the hollow cylinder-like portion. Additional embodiments and aspects are disclosed.

Abstract: A device comprises a capacitor comprising first and second electrodes having a capacitor insulator there-between. The first electrode is elongated and extends elevationally. The first electrode comprises elevationally-extending first conductive material and comprises second conductive material that projects laterally outward from an elevationally-extending part of the first conductive material. The laterally-projecting second conductive material has a vertical thickness that is less than that of the elevationally-extending first conductive material. Support material laterally supports the capacitor and contacts a tip end of the laterally-projecting second conductive material.
