Abstract: A cover layer for micro-electronic components and VLSI circuits is provided for protecting the components and circuits against alpha radiation. The cover layer is produced by ultraviolet cross linking of a negative resist, wherein, as a constituent for absorbing the alpha rays, the negative resist contains a substituted triphosphazene of the formula (I) whose organic radicals are bonded to phosphorus via oxygen and wherein, on a statistical average, 1 through 3 radicals have cross-linkable, light-sensitive groups. The cover layer provided good protection from alpha rays, has low shrinkage during curing and, given high thermal resistance, can be combined when mixing with other negative resists.

Abstract: Linear fluorooligomers having at least two reactive end groups per polymer molecule are incorporated into radiation sensitive polymer systems which have improved continuous temperature resistance and low dielectric constant. The polymer systems can be applied as lacquers. Preferably perfluorated poly-ethers and perfluorated alkanes are used as starting compounds. The polymeric product is usable as a coating for the production of printed multi-layer wirings and economises on through-bores and additional copper intermediate layers.

Abstract: A method and coating material for applying electrically conductive printed patterns to insulating substrates is provided. The coating material includes a non-metallic, grainy carrier substance having metal of the oxidation degree 0 applied thereto. An energy radiation source, particularly of a deflectable laser beam, is used to secure anchoring of the carrier substance to the substrate in the region of the desired printed pattern. As a consequence of a three-dimensional arrangement of the metal, a three-dimensional nuclei distribution is produced that leads to a reliable and fast metallization of the printed pattern on the basis of chemical metal deposition. The method of the invention is especially suited for laser pattern transfer for the manufacture of printed circuit boards.

Abstract: A print head of an ink jet printer is formed by a multilayer structure composed of a plurality of individual photoplastic films, segments of such films having a prescribed contour being removed by a photo-chemical treatment being defined on the individual photoplastic films in successive lamination procedures by the use of masks through which such photoplastic films are exposed. Passivation of unexposed films takes place after every lamination procedure by applying a light-absorbing solution. A three-dimensional structure is built up employing photoplastic films having thicknesses in the range between 10 .mu.m to 50 .mu.m and one or more masks having light transmissive regions which define a desired cross-section for the interior passages of the print head.

Abstract: Sulfur-containing polymers, such as polyphenylene sulfide are stabilized from releasing sulfur-containing exhaust gases by adding an additive polymer having at least one reactive radical selected from the group consisting of amino radicals, amido radicals, imido radicals, and keto radicals therein, and which is of approximate the same thermal stability as the sulfur-containing polymer, to such sulfur-containing polymer. In other embodiments of the invention, sulfur-stabilization is also achieved by incorporating suitable fundamental building blocks of the additive polymer into the sulfur-containing polymer chain in the form of reactive monomers. Further, in other embodiments, additive polymers or oligomers (so-called telecheles) having reactive radicals at their ends can be introduced into the sulfur-containing polymer chain as copolymers.

Abstract: Long-term lubrication of highly loaded lubricating areas or surfaces, such as in very high speed medical and/or dental equipment, is obtained by applying a synthetic film, for example composed of poly(fluoroacrylic acid methyl ester) onto the sliding/moving surfaces, along with a polar oil having high lubricity. Anti-microbial agents can be added to the synthetic film. A pre-coat of molybdenum sulfide (MoS.sub.2) can be provided for the synthetic film. Stationary surface abutting the sliding/moving surfaces, such as cages for ball-bearings, preferably composed of a phenol resin, can function as a reservoir for the anti-microbial agents and the oil.
