Abstract: A method of making an electronic device includes forming an electrically conductive pattern on a substrate, forming a coverlay layer on the substrate and the electrically conductive pattern, forming a partially cured, tacky adhesive layer on the coverlay layer, and forming openings in the coverlay layer and the partially cured, tacky adhesive layer aligned with the electrically conductive pattern. The method includes positioning an IC on the partially cured, tacky adhesive layer and thereafter curing the partially cured tacky adhesive layer to thereby simultaneously mechanically secure and electrically interconnect the IC to the substrate, the IC having bond pads on a surface thereof.
