ABSTRACT:
A method for making a nonvolatile memory device having a field effect transistor for storing information, and a Schottky diode in series with the field effect transistor. The field effect transistor includes source and drain regions in a semiconductor substrate, with a channel region interposed between them and a gate electrode above the channel region. A ferroelectric gate film is sandwiched between the channel region and the gate electrode. In the method, a conductive barrier meterial is deposited in contact with the source region of the field effect transistor to make the Schottky diode. In reading information from the memory device, voltage is applied to a serial circuit consisting of the field effect transistor and the Schottky diode to turn the Schottky diode on.
