Publication number: 20040058088Abstract: Disclosed is a processing method for forming a thick film having an improved adhesion to a surface-modified substrate and an apparatus thereof enabling to form a thick film having the improved adhesion to a polymeric surface by modifying the polymeric surface to have a hydrophilic property. The method includes the steps of preparing a substrate of a polymer material, surface-modifying the substrate, forming a seed layer on the substrate, and forming the thick film on the seed layer. The apparatus includes an unloading area supplying a substrate of a polymer material, a surface treating area modifying a surface of the substrate, a seed layer formation area forming a seed layer on the surface-modified substrate, a thick film formation area forming a thick film on the seed layer, and a loading area loading the substrate.Type: ApplicationFiled: September 2, 2003Publication date: March 25, 2004Inventors: Young-Whoan Beag, Sung Han, Jun-Sik Cho, Cheol-Su Lee, Sung-Soo Koh, Jin-Woo Seok

Publication number: 20030150740Abstract: A complex porous structure of a reticulated foam, felt or fabric types, wherein their metallisation over their entire developed surface, by electrolysis of lead or lead alloys, is made possible by a specific preliminary conductive activation treatment obtained by using two consecutive phases of coating the developed surface of the structures, comprising a first deposition of a conductive polymer, which provides the structures with the required conductivity, and a second thin deposition of conductive lacquer or varnish which ensures the surface protection of the conductive polymer against the deactivating effect of the conductive nature of the latter, due to the cathodic polarisation of the said structures in the electrolytic lead-coating bath.Type: ApplicationFiled: January 30, 2003Publication date: August 14, 2003Inventors: Bernard Bugnet, Denis Doniat

Patent number: 6546751Abstract: A method of providing a decorative metal pattern on an electrically non-conductive substrate, such as a glass or plastic substrate, which includes applying a mixture of heat fusible material, such as glass or plastic, with a metal having a particle size less than about 500 mesh constituting at least 50% of the mixture, to the substrate in the desired pattern, heating the so-applied mixture until the heat fusible material fuses and bonds to the substrate, cleaning the substrate with the pattern thereon, and a electroplating the pattern with the desired finish metal. In one method in which the mixture includes glass, a negative resist is adhesively secured to the substrate and the mixture is applied. The resist disintegrates upon heating. In another method, used when the substrate is plastic, a mixture of plastic and metal in past form is applied to the substrate by silk screening or pad printing to form the pattern.Type: GrantFiled: August 16, 1999Date of Patent: April 15, 2003Inventor: Peter Jaeger

Publication number: 20020074234Abstract: An electroplating process for filling damascene structures on substrates, such as wafers having partially fabricated integrated circuits thereon, includes immersing a substrate, under bias, into a copper plating solution to eliminate thin seed layer dissolution and reduce copper oxide, an initiation step to repair discontinuities in a copper seed layer, superfill plating to fill the smallest features, reverse plating to remove the adsorbed plating additives and their by-products from the substrate, a second superfill plating to fill intermediate size features, a second reverse plating to remove adsorbed plating additives and their by-products from the substrate, and a bulk fill plating with high current density to fill large features. The superfill and reverse plating operations may be repeated more than twice prior to bulk filling in order to provide the desired surface morphology.Type: ApplicationFiled: December 18, 2000Publication date: June 20, 2002Inventors: Valery M.
