Abstract: A method for forming an adhesion layer in contact with a first surface of a substrate and a surface of a layer having electrically conductive properties using electrophotographic imaging compound as a mask is provided. The adhesion layer improves the lamination properties of the electrically conductive layer to the substrate. The improved lamination properties to facilitate and increase the reliability and quality of a resulting product having an electronic circuit formed in accordance with the present invention. The method disclosed herein is well suited for use with rigid polymeric substrates and flexible polymeric substrates.

Abstract: Amorphous silicon thin-film transistors on glass foil are made using exclusively electrophotographic printing for pattern formation, contact hole opening, and device isolation. Toner etch masks are applied by feeding the glass substrate through a laser printer or photocopier, or from laser-printed patterns on transfer paper. This all-printed patterning is a low-cost, large-area circuit processing technology, suitable for producing backplanes for active matrix liquid crystal displays.
