  • Patent number: 8609206
    Abstract: Surface metallization technology for ceramic substrates is disclosed herein. It makes use of a known phenomenon that many metal—metal oxide alloys in liquid state readily wet an oxide ceramic surface and strongly bond to it upon solidification. To achieve high adhesion strength of a metallization to ceramic, a discrete metallization layer consisting of metal droplets bonded to ceramic surface using metal—metal oxide bonding process is produced first. Next, a continuous metal layer is deposited on top of the discrete layer and bonded to it using a sintering process. As a result a strongly adhering, glass-free metallization layer directly bonded to ceramic surface is produced. In particular, the process can be successfully used to metalize aluminum nitride ceramic with high thermal and electrical conductivity copper metal.

  • Patent number: 8557045
    Abstract: An apparatus and method for manufacturing thin-film CdS/CdTe photovoltaic modules in a vacuum environment. The apparatus deposits CdS and CdTe layers onto a substrate using heated pocket deposition, a form of physical vapor deposition (PVD) in which a material thermally sublimes from a thermal sublimation source block and is deposited onto a substrate. The thermal sublimation source block includes a pocket having a lower surface into which an array of holes is formed to house plugs of deposition material. Upon heating, deposition material sublimes from a surface of each plug of deposition material, and the surface of each plug regresses into its corresponding hole while maintaining a constant surface area. The sublimation surface area of deposition material across the pocket remains substantially constant during an extended deposition process, and the deposition material is substantially free of undesired thermal radiation from the substrate.

  • Publication number: 20120177808
    Abstract: Direct resistive heating is used to grow nanotubes out of carbon and other materials. A growth-initiated array of nanotubes is provided using a CVD or ion implantation process. These processes use indirect heating to heat the catalysts to initiate growth. Once growth is initiated, an electrical source is connected between the substrate and a plate above the nanotubes to source electrical current through and resistively heat the nanotubes and their catalysts. A material source supplies the heated catalysts with carbon or another material to continue growth of the array of nanotubes. Once direct heating has commenced, the source of indirect heating can be removed or at least reduced. Because direct resistive heating is more efficient than indirect heating the total power consumption is reduced significantly.

This process gives rise to a number of deposited metallic particle sizes which may be controlled. The compositions prepared by this process are used to produce polymer composites by combining them with readily available commodity and engineering plastics. The polymer composites are used as coatings, or they are used to fabricate articles, such as free-standing films, fibers, fabrics, foams, molded and laminated articles, tubes, adhesives, and fiber reinforced articles.

    Abstract: A continuous, uninterrupted two-step treatment process capable of forming nanometer scale physical structures on the surface of articles fabricated from metallic, ceramic, glass, or plastic materials, and then depositing a thin conformal coating on the nanostructured surface such that the physical structures previously produced are neither masked nor are the dimensions of the physical structures substantially altered. In an additional embodiment, a thicker coating can be grown from the thin conformal coating which itself can be nanostructured as it is deposited. In this case adhesion of the thicker coating is not dependent upon the use of conventional surface pretreatments such as machining, chemical etching, or abrasive blasting. Surface texturing may be performed by ion beam sputtering, and ion assisted coating forms the thin conformal coating, and thicker coating if desired. The treatment process is useful for improving the mechanical, catalytic, chemical, or biological activity of the surfaces so treated.

  • Patent number: 6427622
    Abstract: A hot wire chemical vapor deposition method and apparatus for fabricating high quality amorphous, micro-crystalline, and poly-crystalline thin film silicon, or related materials, devices and large area modules is described. A silane gas impinges upon a hot graphite rod assembly whereas the gas is broken up into its individual constituents, these constituents then depositing on an inert substrate member. The distance between the hot graphite rod assembly and the substrate member is adjustable. A shutter is provided to shield the substrate member as the hot graphite rod assembly is heating up. The hot graphite rod assembly contains a plurality of mutually parallel and coplanar rods that are parallel to the plane of the substrate member, and the hot graphite rod assembly and/or the substrate is oscillated in a direction generally normal to the direction in which the rods extend.

  • Patent number: 6203864
    Abstract: A carbon nanotube is contacted with a reactive substance which is a metal or a semiconductor. The reactive substance is heated to diffuse atoms of the reactive substance into the carbon nanotube so that the carbon nanotube is partially transformed or converted into carbide as a reaction product. Thus, a heterojunction of the reaction product and the carbon nanotube is formed. For example, the carbon nanotube (2) is contacted with a silicon substrate (1). The silicon substrate (1) is heated to cause solid-solid diffusion of Si. As a result, SiC (3) is formed as the heterojunction. At least a part of a filament material of a carbon nanotube is irradiated with electromagnetic wave to deform the filament material.

  • Patent number: 5741557
    Abstract: A method for forming a desired pattern of a material of conductive or non-conductive type on a variety of substrates. It is based on the use of a pen which essentially consists of a refractory tip wetted with the material in the molten state. The pen preferably consists of a pointed tungsten tip attached to the top of a V-shaped tungsten heater, forming a heater assembly. The tip and the heater top portion are roughened at the vicinity of the welding point. In turn, the ends of the V-shaped heater are welded to the pins of a 3-lead TO-5 package base. The pen is incorporated in an apparatus adapted to the direct writing technique. To that end, the pen is attached to a supporting device capable of movements in the X, Y and Z directions, while the substrate is placed on an X-Y stage for adequate X, Y and Z relative movements therebetween. The two pins of the pen are connected to a power supply to resistively heat the heater.
