  • Patent number: 10754093
    Abstract: A method of fabricating polymer modulators includes forming an insulating layer on a platform and depositing and patterning a ground electrode on the insulating layer. A bottom polymer cladding layer, a first blocking layer, a polymer core layer, a second blocking layer, and a top polymer cladding layer are deposited in order. A third blocking layer is deposited on the top cladding layer and patterned to define vias which are used to etch ground openings through the top polymer cladding layer, the second blocking layer, the core layer, the first blocking layer, and the bottom cladding layer to the ground electrode. The openings are filled with electrically conductive material from electrical communication with the ground electrode to a surface of the top polymer cladding layer. The third blocking layer is removed and electrical contacts are formed on the top polymer cladding layer in electrical communication with the electrically conductive material.

  • Patent number: 10375835
    Abstract: The present invention relates to methods of treating metal surfaces to enhance adhesion or binding to substrates, and devices formed thereby. In some embodiments of the present invention, methods of achieving improved bonding strength without roughening the topography of a metal surface are provided. The metal surface obtained by this method provides strong bonding to resin layers. The bonding interface between the treated metal and the resin layer exhibits resistance to heat, moisture, and chemicals involved in post-lamination process steps, and therefore can suitably be used in the production of PCB's. Methods according to some embodiments of the present invention are especially useful in the fabrication of high density multilayer PCB's, in particular for PCB's having circuits with line/spacing of equal to and less than 10 microns. Methods according to other embodiments of the present invention are particularly useful in the coating of metal surfaces in a wide variety of applications.
