    摘要: A semiconductor memory device includes a semiconductor substrate in which a cell region and a core and peripheral region are defined. The device further comprises isolation layers formed in the semiconductor substrate to define active regions, a first gate electrode structure formed in the cell region and a second gate electrode structure formed in the core and peripheral region. Source and drain regions formed in the active regions on respective sides of each of the gate electrode structures and self-aligned contact pads are formed in the cell region in contact with the source and drain regions. An insulating interlayer is formed on the semiconductor substrate between the self-aligned contact pads, and etch stoppers are formed on the insulating interlayer between the self-aligned contact pads in the cell region.

    摘要: A semiconductor device and a method of fabricating a semiconductor device provide high quality cylindrical capacitors. The semiconductor device includes a substrate defining a cell region and a peripheral circuit region, a plurality of capacitors in the cell region, and supports for supporting lower electrodes of the capacitors. The lower electrodes are disposed in a plurality of rows each extending in a first direction. A dielectric layer is disposed on the lower electrodes, and an upper electrode is disposed on the dielectric layer. The supports are in the form of stripes extending longitudinally in the first direction and spaced from each other along a second direction. Each of the supports engages the lower electrodes of a respective plurality of adjacent rows of the lower electrodes. Each one of the supports is also disposed at a different level in the device from the support that is adjacent thereto in the second direction.
