    摘要： A combined adhesion promotion method of a metal to a non-conductive substrate and directly metallizing the non-conductive substrate with the metal. The method involves texturing a non-conductive substrate with a cobalt etch followed by applying a sulfide to the textured non-conductive substrate to provide an electrically conductive surface on the non-conductive substrate. After the surface of the non-conductive substrate has been made electrically conductive, the surface of the non-conductive substrate can be directly metallized. The method reduces the number of process steps for direct metallization of a non-conductive substrate. Thus, the method is more efficient in contrast to conventional methods of metallizing a non-conductive substrate.

    摘要： The invention includes processes for combined polymer surface treatment and metal deposition. Processes of the invention include forming an aqueous solution containing a metal activator, such as an oxidized species of silver, cobalt, ruthenium, cerium, iron, manganese, nickel, rhodium, or vanadium. The activator can be suitably oxidized to a higher oxidation state electrochemically. Exposing a part to be plated (such as an organic resin, e.g. a printed circuit board substrate) to the solution enables reactive hydroxyl species (e.g. hydroxyl radicals) to be generated and to texture the polymer surface. Such texturing facilitates good plated metal adhesion. As part of this contacting process sufficient time is allowed for both surface texturing to take place and for the oxidized metal activator to adsorb onto said part. The part is then contacted with a reducing agent capable of reducing the metal activator to a lower ionic form, or a lower oxidation state. That reduction can result in the formation of metallic catalytic material over the surface of the part. The reduced metal activator can then function to catalyze the electroless deposition of metal such as copper from solution by contacting the part with the plating solution.

    摘要： A method is described of manufacturing perovskite lead scandium tantalate comprising the pre-reaction of scandium and tantalum oxides at temperatures between 1000.degree. C. and 1400.degree. C. to form scandium tantalate. The scandium tantalate is then reacted with lead oxide to form the desired perovskite phase lead scandium tantalate. In one embodiment there is described a method for the deposition of perovskite lead scandium tantalate films from metal organic precusors. The availability of metal organic precursors allows the deposition of thin films directly from solution or by MOCVD techniques. One particular material, lead scandium tantalate Pb(Sc.sub.0.5 Ta.sub.0.5)O.sub.3, is described. The principal features of the invention are the deposition of scandium and tantalum components from solution or by MOCVD onto the required substrate. These are then prereacted to yield scandium tantalate. A lead containing film or vapor is then reacted with the scandium tantalate to form the perovskite phase lead scandium tantalate.
