Patent number: 8609206Abstract: 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.Type: GrantFiled: April 30, 2009Date of Patent: December 17, 2013Inventor: Maxim Seleznev

Apparatus and method for fabricating photovoltaic modules using heated pocket deposition in a vacuum
Patent number: 8557045Abstract: 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.

Publication number: 20120177808Abstract: 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.

Publication number: 20020015907Abstract: Disclosed are thermal transfer elements and processes for patterning solvent-coated layers and solvent-susceptible layers onto the same receptor substrate. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, an optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor. The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.Type: ApplicationFiled: July 24, 2001Publication date: February 7, 2002Applicant: 3M Innovative Properties CompanyInventors: Martin B.

Patent number: 6203864Abstract: 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.Type: GrantFiled: June 8, 1999Date of Patent: March 20, 2001Assignee: NEC CorporationInventors: Yuegang Zhang, Sumio Iijima

Patent number: 5904872Abstract: A heating device is formed by a heating plate formed of silica and having a heating surface for heating an object to be heated, a heating element having a predetermined pattern and fixed to a surface opposing the heating surface of the heating plate, and a reflecting plate formed of silica and brought into tight contact with the surface of the heating plate on which the heating element is formed. This heating device is arranged in a processing vessel in a CVD apparatus, and a semiconductor wafer is placed on the heating device. A process gas is supplied into the processing vessel while the semiconductor wafer is heated, thereby forming a predetermined film on the semiconductor wafer.Type: GrantFiled: September 27, 1995Date of Patent: May 18, 1999Assignees: Tokyo Electron Limited, Shin-Etsu Chemical Co., Ltd.Inventors: Junichi Arami, Kenji Ishikawa, Harunori Ushikawa, Isao Yanagisawa, Nobuo Kawada, Hiroshi Mogi

Patent number: 5741557Abstract: 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.Type: GrantFiled: May 24, 1995Date of Patent: April 21, 1998Assignee: International Business Machines CorporationInventors: Antoine Corbin, Philippe Demoncy, Jacques Foulu, Pierre Sudraud
