Abstract:
1. A semiconductor construction, comprising: a capacitor storage node over a semiconductor substrate, the capacitor storage node having a first thick pillar, a second thick pillar over the first thick pillar, and a narrow neck connecting the second thick pillar to the first thick pillar; first dielectric material along the first thick pillar and not along the second thick pillar; second dielectric material along the second thick pillar and not along the first thick pillar; first capacitor outer electrode material along the first thick pillar and not along the second thick pillar; second capacitor outer electrode material along the second thick pillar and not along the first thick pillar; and an interconnect region laterally offset from the capacitor storage node, the first and second capacitor outer electrode materials electrically coupling with one another in the interconnect region.
