  • Publication number: 20080278278
    Abstract: The present invention is directed to a thick film patterned resistor on a substrate and to a method of forming it. The method involves providing a substrate with opposed surfaces, where one surface is coated with a layer of a resistor composition. A photoresist is applied over the layer of the resistor composition, and a desired pattern in the photoresist is formed, where the pattern leaves certain regions of the resistor composition layer uncovered by the photoresist. The resistor composition layer which is uncovered by the photoresist is etched under conditions effective to leave a mass of loosely bound resistor particles at regions of the resistor composition which are not covered by photoresist. The mass of resistor particles is then removed from the substrate to produce a thick film patterned resistor on the substrate.

  • Patent number: 6631551
    Abstract: A process for forming stable integrated resistors (14) and capacitors (28) on organic substrates (12). The resistors (14) and capacitors (28) are capable of a wide range of resistance and capacitance values, yet can be processed in a manner that does not detrimentally effect the organic substrate (12) or entail complicated processing. The method generally entails the use of thick-film materials usually of the types used to form resistors and capacitors on ceramic substrates. The thick-film materials are applied to an electrically-conductive foil (20) and then heated to bond the thick-film material to the foil (20) and form a solid resistive or capacitive mass (16/30). The foil (20) is then laminated to an organic substrate (12), such that the resistive/capacitive mass (16/30) is attached to and preferably embedded in the organic substrate (12).
