Abstract
A capacitor with an anode, a dielectric on the anode and a cathode on the dielectric. A blocking layer is on the cathode. A metal filled layer is on said blocking layer and a plated layer is on the metal filled layer.
Claims35
A method for forming a capacitor comprising the steps of:
- providing an anode;
- forming a dielectric on said anode;
- applying a cathode on said dielectric;
- applying a blocking layer;
- applying a metal filled layer;
- and
- plating a metal layer wherein said plating is by a method selected from the group consisting of electroplating and electroless plating.
