Method, chemistry, and apparatus for selectively electrodepositing tin-lead solder bumps and other structures at a high deposition rate onto a microelectronic device from a workpiece, such as a semiconductor wafer. Apparatus comprises a reactor chamber containing an electroplating solution having free ions of tin and lead for plating onto the workpiece. A chemical delivery system is used to deliver the electroplatApril 2004
ing solution to the reactor chamber at a high flow rate. A workpiece support is used that includes a contact assembly for providing electroplating power to a surface at a side of the workpiece that is to be plated. The workpiece is electrically contacted at a large plurality of discrete contact points, isolated from exposure to the electroplating solution. An anode, preferably a consumable anode, is spaced from the workplece support within the reaction chamber and is in contact with the electroplating solution. A methane sulfonic acid electrolyte may be used. SELF-HEALING NON-CHROMATE CONVERSION COATINGS FOR ALUMINUM AND ITS ALLOYS
US 6669786 (Concurrel~t Technologies Corp.~ Sampath, K. Chromate-replacement coatings for aluminum and its alloys includes forming a boehmite coating. Layer with A1 (III) ions on an aluminum surface, and applying an ionic conversion coating solution to the coating layer. The ionic conversion coating solution comprises hexavalent and trivalent ions. The trivalent ions are selected from the group consisting of Ce, Ga, Mn, Sc, Ti, Te and V. The hexavalent ions are selected from the group consisting of Mn, Mo, Se and W. The resulting coatings claim to provide corrosion resistance and self-healing effect in any defects present in the coatings. PRETREATMENT FOR ALUMINUM AND ALUMINUM ALLOYS

US 2003234063 Phelps, A. W.; Swartzbaugh, J. T et al. Conversion coatings based on cobalt are described for substrate metals such as aluminum, zinc, magnesium, titanium, cadmium, silver, copper, tin, lead, cobalt, zirconium, beryllium, or indium, their alloys, or items coated with these metals. The conversion coating contains a trivalent or t e t r a v a l e n t cobalt/valence stabilizer complex. The coating bath m a y also contain a preparative agent or solubility control agent. The oxidized cobalt is present in the coating in a "sparingly soluble" form. The valence stabilizers can be either inorganic or organic in nature. Cobalt/valence stabilizer combinations are chosen b a s e d on the well-founded principles of cobalt coordination chemistry. A n u m b e r of cobalt/valence stabilizer combinations that match
