Abstract:
A method of fabricating a ferroelectric FET comprising:preparing a semiconductor substrate; forming a gate electrode; and forming a thin film of polycrystalline crystallographically oriented ferroelectric material located between said semiconductor substrate and said gate electrode, wherein said step of forming said thin film of polycrystalline crystallographically oriented ferroelectric material comprises: providing a liquid precursor containing a plurality of metal moieties in effective amounts for yielding said ferroelectric material upon annealing of said precursor; forming said thin film of ferroelectric material on said substrate utilizing said liquid precursor; and during said step of forming, irradiating one of said liquid precursor or said forming thin film with ultraviolet radiation of sufficient intensity to alter electrical properties in said thin film.
