Patent ID: 7601181

Claim:
A method of making a capacitor comprising: providing a metallic foil; forming a dielectric layer over the metallic foil, wherein the dielectric layer is formed from a solution composition that forms barium titanate during annealing and contains manganese in an amount between 0.002 and 0.05 atom percent of the solution composition; annealing the dielectric layer at a temperature between about 800° C. to 1050° C. and in a reducing atmosphere having an oxygen partial pressure of less than about 10 −8 atmospheres to form a dielectric having a thickness between 0.4 and 1.0 micrometer; and forming a conductive layer over the dielectric, wherein the metallic foil, the dielectric, and the conductive layer form the capacitor, and wherein the dielectric is not re-oxygenated after annealing and wherein the capacitor has a leakage current density of less than approximately 1 milli-amp/cm 2 at 10 volts.
