Abstract:
A capacitor structure includes a plurality of bottom electrodes horizontally spaced apart from each other, a support structure covering sidewalls of the bottom electrodes, a top electrode surrounding the support structure and the bottom electrodes, and a dielectric layer interposed between the support structure and the top electrode, and between the top electrode and each of the bottom electrodes. An uppermost surface of the support structure is positioned at a higher level than an uppermost surface of each of the bottom electrodes.

Claim (Index 31):
A capacitor structure for a dynamic random access memory (DRAM) cell, comprising:\n a plurality of bottom electrodes horizontally spaced apart from each other, each bottom electrode being formed in a cylindrical structure and thereby including an inner side surface, an outer side surface, and an upper surface; a lower support pattern disposed at a middle portion of each bottom electrode of the plurality of bottom electrodes and contacting side surfaces of each bottom electrode of the plurality of bottom electrodes; an upper support pattern disposed at a top portion of the plurality of bottom electrodes and contacting side surfaces of each bottom electrode of the plurality of bottom electrodes, an upper surface of the upper support pattern being positioned at a higher level than upper surfaces of each bottom electrode of the plurality of bottom electrodes, and a lower surface of the upper support pattern being positioned at a lower level than the upper surface of each bottom electrode of the plurality of bottom electrodes; a dielectric layer covering the lower support pattern, the upper support pattern, and each bottom electrode of the plurality of bottom electrodes respectively; and a top electrode covering the dielectric layer, wherein the lower support pattern and the upper support pattern include a plurality of first openings and a plurality of second openings respectively, each of the plurality of first openings and the plurality of second openings extends to outer side surfaces of at least three bottom electrodes of the plurality of bottom electrodes, and each first opening of the lower support pattern vertically overlaps a corresponding second opening of the upper support pattern.
