Patent ID: 8667654

Claim:
A method for manufacturing a capacitor, comprising: forming two metal electrodes; and forming a polycrystalline dielectric layer between the two metal electrodes, forming the dielectric layer including performing a polycrystalline growth of a single dielectric metallic oxide on one of the metal electrodes, performing the polycrystalline growth including performing plural polycrystalline growth cycles that form respective thicknesses of the polycrystalline dielectric layer, wherein performing plural polycrystalline growth cycles includes: forming a first thickness of the dielectric metallic oxide having a first crystallization rate using a first polycrystalline growth cycle; and forming, on the first thickness, a second thickness of the dielectric metallic oxide having a second crystallization rate using a second polycrystalline growth cycle that has at least one growth condition that is different than in the first polycrystalline growth cycle, the first and second crystallization rates being within 10 percent of one another.
