Abstract
A storage electrode of a DRAM cell in a highly-integrated semiconductor device has, in order to secure the surface area thereof greater than that of a conventional tunnel-type storage electrode, an upper plate of storage electrode formed over a lower plate of storage electrode separated therefrom by a predetermined distance, while interposing bars of irregularly shapes formed of a conductive layer to electrically connect the upper and lower plates.
