摘要:
A process for producing metal plated paths on a solid substrate of the kind which has polar functional groups at its surface utilizes a self-assembling monomolecular film that is chemically adsorbed on the substrate's surface. The solid substrate may, for example, be an insulator of the kind used for substrates in printed circuitry or may, as another example, be a semiconductor of the kind used in semiconductor microcircuitry. The chemical reactivity in regions of the ultra-thin film is altered to produce a desired pattern in the film. A catalytic precursor which adheres only to those regions of the film having enough reactivity to bind the catalyst is applied to the film's surface. The catalyst coated structure is then immersed in an electrolers plating bath where metal plates onto the regions activated by the catalyst.

To metallize transparent conductive paths of indium tin oxide (ITO) on substrates of display devices, a solderable metal layer is applied by electroless deposition. If the metal layer is adjacent a liquid crystal display device, the display device may be manufactured and tested prior to the electroless deposition, with only an edge of the substrate being dipped into the deposition bath. Prior to the deposition of the solderable metal layer, the indium tin oxide surface may be reduced and an adhesion improving layer of may also be deposited by above the indium tin surface and below the solderable metal layer. Integrated circuits can then be soldered to the metallized conductive paths.

Methods for the deposition of silver-comprising films on nonconducting substrates, and, more particularly, to deposition of such films that are very thin, are provided. The surface of nonconducting substrates is modified with a superabsorbent polymer to increase silver deposition when compared to a non-modified surface. Also provided are films produced using a swelling agent, whereby porosity of the surface of the nonconducting substrate is increased, thereby permitting increased silver deposition when compared to an unmodified surface.

A method for forming an electrocatalyst for fuel cell applications comprises electrolessly depositing a first plurality of nickel particles onto carbon-support particles. The nickel particles are formed from a nickel ion-containing aqueous solution. At least a portion of the nickel particles are replaced with platinum via a galvanic displacement reaction to form a second plurality of nickel particles coated with a platinum layer. During this displacement reaction step, the nickel particles are heated to a temperature sufficient to form the platinum layer. Finally, the second plurality of nickel particles is optionally incorporated into a cathode layer of a fuel cell.

摘要:
A ceramic electronic component that includes a ceramic main body, a coating film and external electrodes on the surface of the ceramic main body. The coating film is selectively formed on the surface of the ceramic main body by applying, to the surface of the ceramic main body, a resin-containing solution that etches the surface of the ceramic main body so as to ionize constituent elements of the ceramic main body. The coating film includes a resin and the constituent elements of the ceramic main body, which were ionized and deposited from the ceramic main body.
