Abstract
An improved method for forming a capacitor is provided as is a capacitor, or electrical component, formed by the method. The method includes providing an aluminum containing anode with an aluminum oxide dielectric thereon; forming a cathode on a first portion of the aluminum oxide dielectric; bonding an anode lead to the aluminum anode on a second portion of the aluminum oxide by a transient liquid phase sintered conductive material thereby metallurgical bonding the aluminum anode to the anode lead; and bonding a cathode lead to said cathode.
