Abstract
According to a semiconductor device and a method of manufacturing the same, a storage node has an increased capacity, and a resistance against soft error is improved. A GND interconnection is formed on a first interconnection layer including storage node portions with a dielectric film therebetween. Thereby, the storage node portions, the dielectric film, and the GND interconnection form a capacity element of the storage node portion. The first interconnection layer is arranged symmetrically around the center of the memory cell, and a plurality of memory cells having the same layout and neighboring to each other are arranged along the word lines.
