    Abstract: A method for making thick-film conductor line patterns having conductor linewidths and spacings which are each less than about 5 mils. The method is especially useful in manufacturing fine-line hybrid circuits. The method involves forming a conductor line circuit pattern of thick-film material on a principle surface of a substrate. The principle surface of the substrate is masked so that selected portions of the conductor line circuit pattern are exposed. The exposed portions of the pattern are then removed from the substrate to reduce the conductor linewidths and spacings of the pattern to less than about 5 mils.

    Abstract: A method is provided for etching and removing extraneous molybdenum or debris on ceramic substrates such as semiconductor devices and also for molybdenum etching in the fabrication of molybdenum photomasks. The method employs a multi-step process using an acidic aqueous solution of a ferric salt to remove (etch) the molybdenum debris followed by contacting the treated substrate with an organic quaternary ammonium hydroxide to remove any molybdenum black oxides which may have formed on the exposed surface of treated molybdenum features in ceramic substrates. The method is environmentally safe and the waste solutions may be easily waste treated for example by precipitating the ferric salts as ferric hydroxide and removing anions such as sulfate by precipitation with lime. The method replaces the currently used method of employing ferricyanide salts which create serious hazardous waste disposal and environmental problems.

    Abstract: A method of manufacturing printed circuit boards is disclosed wherein metallic conductive structures are produced in a desired pattern on a carrier board of isolating material. The method begins with the provision of a carrier board having a metal foil laminated to its surface and thereafter forming conductive traces on the carrier board, deactivating the carrier board to remove substantially all substances deposited on the carrier board other than the conductive traces and forming final conductive structures by electroless chemical metal deposition on the pattern of conductive traces. Circuit boards manufactured in accordance with such a method will have final conductor structures with base layer portions of the original laminated metal foil. In a preferred embodiment, the step of deactivating the carrier board involves rinsing the carrier board with hydrochloric acid. The method can be used for manufacturing single-layer or multilayer printed circuit boards with or without through-holes and permits the formation of conductor structures in the range of 50 micrometers or less.

    Abstract: After the etching away of copper to selectively expose surface areas of insulating resin material in a printed circuit process based upon metal-clad insulating substrate material, the exposed surface areas of insulating material are contacted with a liquid treatment composition effective to soften or swell the resin material such that residual metal species otherwise associated with the surface area are removed or, at the least, become entrapped or encapsulated below a surface of resin, such that the surface insulation resistance afforded by the insulating surface areas of the printed circuit is improved.

    Abstract: Semiconductor switch modules have positive and negative electrical input connections which must be spaced adequately to prevent a short circuit flashover between the polarities. This terminal spacing is defined by the strike distance through air or creepage distance through air along an insulating surface between the two input connections given the operating voltage per regulatory agency requirements. The inductance of the switch connections is ultimately limited by this terminal spacing. A novel conformal solid insulation scheme between the bus structure and switch module eliminates the strike or creepage paths through air and allows for reduced terminal spacing and lower inductance while meeting regulatory agency requirements.
