Abstract
A semiconductor memory cell and a process for formation thereof is disclosed. A capacitor is disposed below a transistor, so that a DRAM cell that may be suitable for a high density semiconductor device is produced. A semiconductor device according to the present invention includes: a buried capacitor consisting of a storage electrode, a dielectric layer and a plate electrode formed on a substrate in a planar form; and a transistor formed above the capacitor, a source/drain region of the transistor being connected to the storage electrode of the capacitor.
