Acceptor Doped Barium Titanate Based Thin Film Capacitors on Metal Foils and Methods of Making Thereof

摘要

The present invention is directed to a dielectric thin film composition comprising: (1) one or more barium/titanium-containing additives selected from (a) barium titanate, (b) any composition that can form barium titanate during firing, and (c) mixtures thereof; dissolved in (2) organic medium; wherein the barium/titanium-containing additives are not intentionally modified or doped; wherein the composition has been annealed in an environment having an oxygen partial pressure of less than about 10^-7 atmospheres and/or at a temperature in the range of 700° C. and 1050° C.; wherein a capacitor comprising the composition would have a loss tangent of greater than about 0.07; and wherein the composition is not reoxygenated.
