  • Patent number: 8568822
    Abstract: An apparatus and method for incorporating discrete passive components into an integrated circuit package. A metal layer is formed over a surface of a substrate. A layer of photosensitive material is then formed over the metal layer. Using standard photolithographic processing, a pattern is formed with the photosensitive material to expose at least one region of the metal layer. The remaining photosensitive material protects the underlying metal during metal etching. The substrate is then subjected to a metal etching process to remove the metal that is not protected by the photosensitive material. The remaining photosensitive material is then removed from each remaining area of the metal layer. The discrete passive components can then be attached to the formed metal lands.

  • Patent number: 8545932
    Abstract: A porous silicon zone is metallized by performing in situ reduction of metallic ions dissolved in an aqueous solution and fixing of the metallic particles obtained on said zone in a single step. This step consists in particular in bringing the solution containing the metallic ions into contact with the zone to be metallized, the surface whereof has previously been functionalized to enable in situ reduction of the metallic ions and fixing of the metallic particles. Functionalization of the porous silicon zone is achieved by grafting two particular and distinct types of chemical functions. The first function used is a chelating chemical function for the metallic ions and/or for the metal corresponding to the metallic ions, whereas the second function is a reducing chemical function for the metallic ions. Such a metallization can be used for producing an electrically conducting porous diffusion layer of a fuel cell.

The at least one isolation layer has sufficient properties to minimize particle displacement on a top surface of the at least one isolation layer. The at least one isolation layer has a greater acoustic impedance than that of the dielectric layer.

  • Patent number: 8524311
    Abstract: Polymer materials make useful materials as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision. Regardless of which polymer is used, the basic construction method is the same. A layer of polymer is laid down. A layer of metal is applied to the polymer and patterned to create electrodes and leads for those electrodes. A second layer of polymer is applied over the metal layer and patterned to leave openings for the electrodes, or openings are created later by means such as laser ablation. Hence the array and its supply cable are formed of a single body.

  • Patent number: 8507032
    Abstract: A magnetic storage medium is formed of magnetic nanoparticles that are encapsulated within nanotubes (e.g., carbon nanotubes), which are arranged in a substrate to facilitate the reading and writing of information by a read/write head. The substrate may be flexible or rigid. Information is stored on the magnetic nanoparticles via the read/write head of a storage device. These magnetic nanoparticles are arranged into data tracks to store information through encapsulation within the carbon nanotubes. As carbon nanotubes are bendable, the carbon nanotubes may be arranged on flexible or rigid substrates, such as a polymer tape or disk for flexible media, or a glass substrate for rigid disk. A polymer may assist holding the nano-particle filled carbon-tubes to the substrate. Magnetic fields may be applied to draw the carbon nanotubes into data tracks and orient the carbon nanotubes within the data tracks.
