  • Publication number: 20140097537
    Abstract: Certain embodiments of the present invention include a versatile and scalable process, “patterned regrowth,” that allows for the spatially controlled synthesis of lateral junctions between electrically conductive graphene and insulating h-BN, as well as between intrinsic and substitutionally doped graphene. The resulting films form mechanically continuous sheets across these heterojunctions. These embodiments represent an element of developing atomically thin integrated circuitry and enable the fabrication of electrically isolated active and passive elements embedded in continuous, one atom thick sheets, which may be manipulated and stacked to form complex devices at the ultimate thickness limit.

  • Patent number: 8551559
    Abstract: The invention relates to a method for producing a plastic molded part (9) comprising an integrated conductor path (3), which plastic molded part is used in particular as an intermediate product to be further processed into an electrically heatable mirror (1). The method steps are: a) producing a substrate (7) from a carrier body (2) made of an electrically insulating plastic material having a conductor path (3) made of an electrically conductive material on or in a surface (8) of the carrier body (2), b) flooding the surface (8) of the substrate (7) equipped with the conductor path (3) or the surface (11) of the substrate (7) opposite said surface with a liquid, electrically insulating coating material. The flooding evens out depressions due to uneven shrinkage in the thick and thin areas of the carrier body and a smooth surface can be produced, which can subsequently be covered with a reflective layer.

  • Publication number: 20130251892
    Abstract: A method of forming a wiring pattern is provided. In the method, an adhesive material is coated on a substrate to form an adhesive layer, and then a patterned mask is provided on the adhesive layer, wherein the patterned mask has an opening defining a wiring pattern, and then an electrically conductive paste is filled in the opening, and subsequently the patterned mask is removed so as to form the wiring pattern on the substrate. In the method of the present invention, a wiring pattern is formed by using a screen printing method, but not by using an etching method. As a result, there are no etching contamination issues. Furthermore, the difficulty in etching the finer wiring patterns from the copper foil can be alleviated.
