ABSTRACT:
A memory cell comprising a MOSFET formed on a principle surface of a semiconductor substrate and an information storage capacitor having a storage electrode formed in or on the substrate so as to contact with a drain region of the MOSFET, and a capacitor electrode formed adjacent to the storage electrode with a capacitor insulator film being sandwiched between the storage electrode and the capacitor electrode. The storage electrode is connected to the drain region of the MOSFET through a thin barrier layer which is formed between the drain region and the storage electrode region so as to prevent impurities in the storage electrode from being diffused into the drain region.
