Abstract
Capacitor anodes that include metallic columns formed on a substrate so as to form a porous microstructure and methods of making the anodes are described. The metallic columns can be distinct from one another and project outward from the substrate. Also described is the formation of the metallic columns on the substrate by vapor deposition, including glancing angle deposition (GLAD), and by etching a portion of a metal layer. High capacitance capacitors made from the capacitor anodes are also described.
