  • Method of making ferroelectric memory devices
    Patent number: 5024964
    Abstract: A monolithic semiconductor integrated circuit-ferroelectric device is disclosed together with the method of manufacturing same. The ferroelectric device preferably consists of a layer of stable ferroelectric potassium nitrate disposed between electrical contacts positioned on opposite surfaces of the ferroelectric layer. The ferroelectric layer has a thickness of less than 110 microns, and preferably falling within a range of from 100 Angstrom units to 25,000 Angstrom units. The process of manufacturing the monolithic structure is multi-stepped and is particularly adapted for fabricating a potassium nitrate ferroelectric memory on a semiconductor integrated circuit.
