  • Publication number: 20120125514
    Abstract: Embodiments of the present invention relates generally to the manufacture of printed circuit boards (PCB's) or printed wiring boards (PWB's), and particularly to methods for treating smooth copper surfaces to increase the adhesion between a copper surface and an organic substrate. More particularly, embodiments of the present invention related to methods of achieving improved bonding strength of PCBs without roughening the topography of the copper surface. The bonding interface between the treated copper and the resin layer of the PCB exhibits excellent resistance to heat, moisture, and chemicals involved in post-lamination process steps.

  • Patent number: 8173630
    Abstract: This invention provides redox-active molecules attached to polypodal (e.g., bipodal, tripodal, quadrapodal, pentapodal, etc.) tethers that can be used for attachment of the redox-active molecules to a substrate (e.g., an electrode). The tethered redox-active molecules are useful for the fabrication of memory devices.

  • Patent number: 7737433
    Abstract: The electronic properties of molecular junctions of the general type carbon/molecule/TiO2/Au as examples of “molecular heterojunctions” consisting of a molecular monolayer and a semiconducting oxide. Junctions containing fluorene bonded to pyrolyzed photoresist film (PPF) were compared to those containing Al2O3 instead of fluorene, and those with only the TiO2 layer. The responses to voltage sweep and pulse stimulation were strongly dependent on junction composition and temperature. A transient current response lasting a few milliseconds results from injection and trapping of electrons in the TiO2 layer, and occurred in all three junction types studied. Conduction in PPF/TiO2/Au junctions is consistent with space charge limited conduction at low voltage, then a sharp increase in current once the space charge fills all the traps. With fluorene present, there is a slower, persistent change in junction conductance which may be removed by a reverse polarity pulse.

  • Patent number: 7642546
    Abstract: According to some embodiments, an article of manufacture comprises a substrate; a molecular layer on the substrate comprising at least one charge storage molecule coupled to the substrate by a molecular linker; a solid barrier dielectric layer directly on the molecular layer; and a conductive layer directly on the solid barrier dielectric layer. In some embodiments, the solid barrier dielectric layer is configured to provide a voltage drop across the molecular layer that is greater than a voltage drop across the solid barrier dielectric layer when a voltage is applied to the conductive layer. In some embodiments, the molecular layer has a thickness greater than that of the solid barrier dielectric layer. The article of manufacture contains no electrolyte between the molecular layer and the conductive layer.
