Abstract:
1. A semiconductor structure, comprising: a semiconductor substrate; a digit line supported by the semiconductor substrate, the digit line comprising a first region, the first region having an upper surface at a first elevational height over the semiconductor substrate; a dummy structure supported by the semiconductor substrate, the dummy structure comprising a second region; and the second region having an upper surface at a second elevational height over the semiconductor substrate, the first and second elevational heights being about the same as one another; a first insulative material supported by the semiconductor substrate and being over the digit line region; a second insulative material supported by the semiconductor substrate and being over the dummy structure region; a capacitor structure supported by the second insulative material, the capacitor structure including a first capacitor electrode, a second capacitor electrode and at least one dielectric material between the first and second capacitor electrodes; a first conductive interconnect extending upwardly from the digit line region and through the first insulative material, the first conductive interconnect being of a composition; and a second conductive interconnect extending upwardly from the dummy structure region, through only one of the first and second capacitor electrodes and through the second insulative material; the second conductive interconnect being of the same composition as the first conductive interconnect.
