Patent ID: 7923816

Claim:
A semiconductor device comprising: a capacitor element comprising a flat-plate-type lower electrode provided over a semiconductor substrate, a flat-plate-type upper electrode provided over said lower electrode in parallel therewith, and a capacitor film provided between said lower electrode and said upper electrode; a first contact plug brought into contact with the bottom surface of said lower electrode, and is composed of a metal material; a first impurity-diffused layer provided in the surficial portion of said semiconductor substrate; a gate electrode provided over said semiconductor substrate, and on the lateral side of said first impurity-diffused layer; a second impurity-diffused layer provided in said semiconductor substrate on the lateral side of said gate electrode, while being opposed with said first impurity-diffused layer; a bit line provided over said semiconductor substrate; and a second contact plug connecting said bit line and said second impurity-diffused layer, and is composed of a copper-containing metal, wherein said capacitor film has a film which contains an organic molecule as a constituent, wherein said upper electrode comprises a first and second layer, wherein said first contact plug is brought into contact with said first impurity-diffused layer, and is composed of a copper-containing metal, wherein said capacitor element is provided more closer to said substrate than said bit line is, wherein a first region having said capacitor element and said bit line, and a second region having a first interconnect provided over said semiconductor substrate, are provided over said semiconductor substrate, and said bit line and said first interconnect are provided at the same level of height, said first region is arranged according to a lattice pattern, and said second region is not arranged according to the lattice pattern.
