  • Method for manufacture of fine line circuitry
    Patent number: 9713266
    Abstract: The present invention relates to a method for manufacture of fine line circuitry in the manufacture of printed circuit boards, IC substrates and the like. The method utilizes a first conductive layer on the smooth surface of a build-up layer and a second conductive layer selected from electrically conductive polymers, colloidal noble metals and electrically conductive carbon particles on the roughened walls of at least one opening which are formed after depositing the first conductive layer.
    Type: Grant
