The Economics of Modeling and Simulation

An Si oxide film, an oriented paraelectric oxide thin film and an oriented ferroelectric thin film are laminated on an Si single crystal substrate having a region for a source and a drain. A conductor thin film is formed in a portion not covered with an insulating film. A laminated structure formed of the Si oxide film, the oriented paraelectric oxide thin film and the oriented ferroelectric thin film is used as a gate of a transistor. The Si oxide film functions as a carrier injection inhibiting layer.
