Abstract

A driver transistor including a gate electrode is formed on the surface of a p well of a silicon substrate. A silicon oxide film and a silicon nitride film are formed to cover the driver transistor. An interlayer insulator film is formed on the silicon nitride film. A contact hole is arranged to planarly overlap with at least the gate electrode. Thus, a semiconductor device capable of performing desired operations and reducing a memory cell area is obtained.
