Abstract

Short and long sides of each of capacitors held by a semiconductor memory device are respectively made shorter and longer so that the capacitors are laid over memory cell regions adjacent to each other. Thus, large capacity type capacitors whose circumferential length increases and total capacitor area greatly increases can be obtained without so increasing plane areas of the capacitors.
