Abstract

A new class of high dielectric constant materials is presented based on binary and ternary amorphous metal oxides. These films are compatible with low temperature processing and can be used with conventional metal electrodes like TiN. Metal alloys of both Tantalum oxide and titanium oxide will be discussed with dielectric constants as high as 62 and leakage currents of less than 10-8 A/cm2 at IMV/cm.
