Patents by Inventor Ludwig Heitzer

Ludwig Heitzer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20070290346
    Abstract: The invention pertains to a method for manufacturing an electronic component with a semiconductor element (1) that is contacted and fixed on a substrate surface (2). The method is characterized in that the rear side of the semiconductor element and/or the substrate surface is coated with an adhesive structure consisting of a first component (3) that solidifies, particularly hardens or cures, and an electrically conductive second component (4) that does not solidify, wherein the semiconductor element is bonded to the substrate surface in a contacting fashion. The electronic component is characterized in that a structured adhesive layer arranged between the semiconductor element and the substrate surface comprises a solidifying first component (3) and an electrically conductive non-solidifying second component (4).

  • Patent number: 7294916
    Abstract: A semiconductor device with a thinned semiconductor chip and a method for producing the latter is disclosed. In one embodiment, the thinned semiconductor chip has a top side with contact areas and a rear side with a rear side electrode. In this case, the rear side electrode is cohesively connected to a chip pad of a circuit carrier via an electrically conductive layer. In another embodiment, the thinned semiconductor chips of this semiconductor device according to the invention have low-microdefect edge side regions with semiconductor element structures and edge sides patterned by etching technology.

  • Publication number: 20070105394
    Abstract: A method for coating a structure that includes at least one semiconductor chip involves electrostatically depositing coating particles on the areas of the structure to be coated. The coating particles are first applied to a carrier and the latter is electrostatically charged with the coating particles. The structure including at least one semiconductor chip is charged electrostatically to a polarity opposite to the carrier. The carrier and/or the structure are then moved towards one another in the direction of an area of the structure to be coated until the coating particles jump to the areas of the structure to be coated and adhere there. The coating particles are liquefied by heating the area with coating particles to form a coating.
