Abstract: Metallic silver is deposited upon the surface of a nonconducting substrate using a multi-step wet deposition process. The surface is cleaned, and then activated in an aqueous solution containing stannous tin. The silver is deposited as a colloidal material from an aqueous solution of a silver-containing salt, a reduction agent that reduces the salt to form the metallic silver, and a deposition control agent that prevents the silver from nucleating throughout the solution. After the substrate is coated, the coating is stabilized in an aqueous solution of a salt of a metal from the platinum group of gold, dissolved in dilute hydrochloric acid. The process is particularly effective for depositing uniform films of 2 to 2000 Angstroms thickness, which strongly adhere to the substrate.

Abstract: An improvement is proposed in a frame-supported pellicle consisting of a frame member and a thin transparent polymer membrane adhesively bonded to the frame member used for dustproof covering of a photomask in a photolithograpic patterning work of electronic devices. The improvement comprises using a specific fluorocarbon group-containing organosiloxane-based polymeric composition as an adhesive for adhesively bonding the frame member and the polymer membrane. This adhesive is effective even when the polymeric membrane is formed from a fluorocarbon polymer which is hardly susceptible to adhesive bonding with conventional adhesives. In addition, the adhesive bonding by use of this specific adhesive is highly durable even under irradiation with ultraviolet light.

Abstract: A process for producing defect free multilayer printed circuit boards using low pressure lamination with a cyanate ester laminate. Alternate layers of cyanate ester core and prepreg materials are stacked and at least partially cured under pressure and elevated temperatures to produce a multilayer laminated printed circuit board. The use of a low pressure cure avoids the storage of stress within the laminate. Such stress would otherwise produce microcracking and/or delamination of the circuit board when the stress is released during the subsequent thermal cycling or exposure to caustics attendant with working and reworking of the printed circuit board.

Abstract: A metal film high in reflectivity and excellent in adhesion to a synthetic resin substrate even in the case where the metal film is sufficiently thin, is formed on a surface of the substrate by sputtering a metal target through an inert gas ion beam drawn out of an ion source in a vacuum vessel. An aluminum film coated matter formed by coating a surface of a synthetic resin substrate with an aluminum film, is characterized in that the aluminum film contains aluminum crystals at a portion in the film at a depth of not more than 600 .ANG. from a film surface thereof which contacts with the substrate. The aluminum crystals has a relation in which a crystal axis <111> perpendicular to a (111) plane is perpendicular or substantially perpendicular to the film surface. Also, the aluminum crystals exhibits a diffraction X-ray spectrum of a (111) plane when measured by X-ray diffraction according to a diffractometer method under the following conditions: target: Cu, X-ray type: K.alpha.

Abstract: An alloy having a low reactivity towards certain high temperature superconducting materials at temperatures up to about 10.degree. C. lower than the melting point of the alloy. The alloy is a ternary silver-based alloy consisting, by weight, of 0.5-9% palladium, 20-40% gold, balance silver. Using the alloy and a superconducting material of the type R-Ba-Cu-O, where R is yttrium or a rare earth element, composite conductors can be formed at temperatures equal or higher than the temperature of peritectic decomposition of the superconductor. The alloy may also be used as a buffer layer or cladding material on substrates having unacceptably high reactivity towards the superconducting material.
