A capacitor having a pear-shaped cross section is provided. In one embodiment, the pear-shaped capacitor is a stacked container capacitor used in a dynamic random access memory circuit with a bit-line-over-capacitor construction. Each capacitor is at a minimum bit line distance from all adjacent bit line contacts, and also at a minimum capacitor distance from all adjacent capacitors along a substantial portion of its perimeter.
