Abstract

An improved monolithic semiconductor integrated circuit-ferroelectric device is disclosed together with the method of manufacturing the same. It was found that the preferred ferroelectric material, namely Phase III potassium nitrate, is extremely sensitive to moisture requiring unique processing steps to fabricate the structure. The process of manfacturing the monolithic structure is multi-stepped and is particularly adapted for fabricating a potassium nitrate ferroelectric memory on a semiconductor integrated circuit.
