Abstract: Multi-terminal capacitor devices and methods of making multi-terminal capacitor devices are described herein. The multi-terminal capacitor devices may include a plurality of individual capacitors arranged in a single device layer, such as high surface area capacitors. A individual capacitor may include an aluminum foil-based electrode, an aluminum oxide dielectric layer conformal with the aluminum foil-based electrode, and a conductive material electrode, such as a conducting polymer or a conductive ceramic, in conformal contact with the dielectric layer.

Abstract: An aluminum alloy fin stock material comprising about 0.9-1.4 wt. % Si, 0.3-0.6 wt. % Fe, 0.20-0.60 wt. % Cu, 1.0-1.7 wt. % Mn, 0.01-0.25 wt. % Mg, 0.01-3.0 wt. % Zn, up to 0.10 wt. % Ti, with remainder Al and impurities at ?0.15 wt. %. The aluminum alloy fin stock material is produced by a process including the steps of direct chill casting an ingot, hot rolling the ingot after the direct chill casting, cold rolling the aluminum alloy to an intermediate thickness, inter-annealing the aluminum alloy cold rolled to an intermediate thickness at a temperature between 200 and 400° C., and cold rolling the material after inter-annealing to achieve % cold work (% CW) of 20 to 40%. The aluminum alloy fin stock material possesses an improved combination of pre- and/or post-braze strength, thermal conductivity, sag resistance and/or corrosion potential.
