Epitaxial Deposition Of Diamond (epo) Patents (Class 257/E21.095)
  • Patent number: 8999846
    Abstract: An integrated circuit structure includes a plurality of insulator layers (connected to each other) that form a laminated structure. Further included are via openings within each of the insulator layers, and conductive via material within the via openings. The conductive via material within corresponding via openings of adjacent insulator layers are electrically connected to form continuous electrical via paths through the insulator layers between the top surface and the bottom surface of the laminated structure. Within each of the continuous electrical via paths, the via openings are positioned relative to each other to form a diagonal structural path of the conductive via material through the laminated structure. The corresponding via openings of the adjacent insulator layers partially overlap each other. The diagonal structural paths are non-perpendicular to the top surface and the bottom surface.

  • Patent number: 8158455
    Abstract: First and second synthetic diamond regions are doped with boron. The second synthetic diamond region is doped with boron to a greater degree than the first synthetic diamond region, and in physical contact with the first synthetic diamond region. In a further example embodiment, the first and second synthetic diamond regions form a diamond semiconductor, such as a Schottky diode when attached to at least one metallic lead.

  • Patent number: 8067296
    Abstract: The present invention provides a method of manufacturing a semiconductor device in which a thinned substrate of a semiconductor or semiconductor device is handled without cracks in the substrate and treated with heat to improve a contact between semiconductor back surface and metal in a high yield and a semiconductor device may be manufactured in a high yield. In the method of manufacturing a semiconductor device according to the present invention, a notched part is formed from a surface to a middle in a semiconductor substrate by dicing and the surface of the substrate is fixed to a support base. Next, a back surface of the substrate is ground to thin the semiconductor substrate and then a metal electrode and a carbon film that is a heat receiving layer are sequentially formed on the back surface of the substrate. Next, the carbon film is irradiated with light at a power density of 1 kW/cm2 to 1 MW/cm2 for a short time of 0.

  • Patent number: 7939367
    Abstract: The invention is a method for growing a critical adherent diamond layer on a substrate by Chemical Vapor Deposition (CVD) and the article produced by the method. The substrate can be a compound semiconductor coated with an adhesion layer. The adhesion layer is preferably a dielectric, such as silicon nitride, silicon carbide, aluminum nitride or amorphous silicon, to name some primary examples. The typical thickness of the adhesion layer is one micrometer or less. The resulting stack of layers, (e.g. substrate layer, adhesion layer and diamond layer) is structurally free of plastic deformation and the diamond layer is well adherent to the dielectric adhesion layer such that it can be processed further, such as by increasing the thickness of the diamond layer to a desired level, or by subjecting it to additional thin film fabrication process steps. In addition to preventing plastic deformation of the layer stack, the process also reduces the formation of soot during the CVD process.

  • Patent number: 7768091
    Abstract: In a conventional ultraviolet sensing device using a diamond semiconductor in a light-receiving unit, an Au-based electrode material is used for both a rectifier electrode and an ohmic electrode. However, the Au-based electrode material has fatal defects, such as poor adhesion to diamond, low mechanical strength, and furthermore poor thermal stability. While avoiding complication of the device structure and exploiting the characteristics of a photoconductive sensing device, by using a carbide compound (TiC, ZrC, HfC, VC, NbC, TaC, CrC, MoC, and WC) of a high melting metal having a high mechanical strength for a rectifier electrode and/or a ohmic electrode, there is provided an extremely heat-stable diamond ultraviolet sensor having a light-receiving sensitivity to ultraviolet light having a wavelength of 260 nm or less.

  • Patent number: 7736435
    Abstract: A method for producing a single crystals by preferential epitaxial growth of {100} face, comprising the steps of (1) growing the crystal on a single crystal {100} substrate; (2) forming on the side of the grown crystal a surface parallel to a {100} face different from the {100}face in the growth direction, and (3) growing the crystal on the formed {100} surface; and the steps (2) and (3) being performed once or more than once. A method for producing a single-crystal diamond using a metallic holder for the single-crystal diamond having a crystal holding portion which is raised above an outer peripheral portion of the holder, is part from the outer peripheral portion of the holder, and has a recessed shape. The methods enable the production of a large single-crystal diamond in a comparatively short time at low cost.

  • Patent number: 7695564
    Abstract: The present invention is directed to a method for fabricating a thermal management substrate having a Silicon (Si) layer on a polycrystalline diamond film, or on a diamond-like-carbon (DLC) film. The method comprises acts of fabricating a separation by implantation of oxygen (SIMOX) wafer; depositing a polycrystalline diamond film onto the SIMOX wafer; and removing various layers of the SIMOX wafer to leave a Si overlay layer that is epitaxially fused with the polycrystalline diamond film. In the case of the DLC film, the method comprises acts of ion-implanting a Si wafer; depositing an amorphous DLC film onto the Si wafer; and removing various layers of the Si wafer to leave a Si overlay structure epitaxially fused with the DLC film.
