Abstract

A capacitor structure includes a plurality of lower electrodes on a substrate, the lower electrodes having planar top surfaces and being arranged in a first direction to define a lower electrode column, a plurality of lower electrode columns being arranged in a second direction perpendicular to the first direction to define a lower electrode matrix, a plurality of supports on upper sidewalls of at least two adjacent lower electrodes, a dielectric layer on the lower electrodes and the supports, and an upper electrode on the dielectric layer.
