Abstract
Fabricating an electrode for capacitor includes performing a first set of one or more preliminary oxide formation operations on a sheet of material. The method also includes performing a capacitance test on the sheet of material so as to determine the capacitance of the sheet of material after the one or more preliminary oxide formation operations. The method proceeds on a first path in response to a first result of the capacitance test and on a second path in response to a second result of the capacitance test. The first path includes performing a second set of the one or more preliminary oxide formation operations on the sheet of material so as to reduce the capacitance of the sheet of material below the determined capacitance. The second path excludes performing any preliminary oxide formation operations on the sheet of material.
