Patent number: 6940047Abstract: A floating substrate reactor allows heat treatment of a series of semiconductor substrates, one by one. The heat treatment occurs while flowing gas suspends a substrate between two heated surfaces of the reactor. The two heated surfaces each have multiple heating zones. The heating zones are heated to desired temperature(s) and a substrate is then loaded into the reactor for heat treatment. Upon loading, the relatively cold substrate absorbs heat and cools the process chamber. A heat spike, which can be varied, is applied to the heating zones to heat the reactor to the desired temperature again. The substrate, however, is unloaded from the reactor before the temperatures of the heating zones have reached the desired temperature. After the heating zones have reached the desired temperature, the next substrate in the series of substrates is loaded into the reactor for heat treatment.Type: GrantFiled: November 14, 2003Date of Patent: September 6, 2005Assignee: ASM International N.V.Inventors: Tom A. van Kesteren, Jan Zinger

Patent number: 6905333Abstract: A method is provided for heating a substrate in a process chamber using a heated chuck. In accordance with the method, the substrate is lowered onto the chuck and heated to a first temperature less than a temperature of the chuck. The substrate is then raised away from the chuck, and a process is carried out on the substrate while the substrate is supported above the chuck. The substrate is then lowered back to the chuck and heated to a second temperature greater than the first temperature for further processing of the substrate.Type: GrantFiled: September 10, 2003Date of Patent: June 14, 2005Assignee: Axcelis Technologies, Inc.Inventor: Gerald Cox

Patent number: 6902395Abstract: A pedestal for use in a high temperature vertical furnace for the processing of semiconductor wafers provides a closure and heat insulation for the lower end of the furnace and is a wafer boat support. The pedestal, comprising quartz-enveloped insulation material, supports a wafer boat at a boat support level and is provided with an upper section disposed above the boat support level. The upper section comprises enveloped insulating material. The envelope of the upper section is also formed of quartz and the insulating material in the upper section has a lower thermal conductance than the insulating material in a lower quartz enveloped section.Type: GrantFiled: March 13, 2003Date of Patent: June 7, 2005Assignee: ASM International, N.V.Inventors: Theodorus Gerardus Maria Oosterlaken, Frank Huussen, Timothy Robert Landsmeer, Herbert Terhorst

In one embodiment, a processing system includes a transfer chamber having at least one processing chamber and a substrate staging system coupled thereto. The staging system includes a load lock chamber having a first port coupled to the transfer chamber and a heat treating station coupled to a second port of the load lock chamber. A load lock robot is disposed in the load lock chamber to facilitate transfer between the heat treating station and the load lock chamber.Type: GrantFiled: September 12, 2002Date of Patent: May 24, 2005Assignee: Applied Materials, Inc.Inventors: Robert Z. Bachrach, Wendell T. Blonigan

Patent number: 6796795Abstract: A method and apparatus for loading a substrate is applied to a semiconductor manufacturing apparatus in which a substrate is carried in a vacuum-processing chamber, and loaded on a heated processing table, and further is applied with predetermined processing in a cold-wall processing mode. In the method, for example, the substrate is temporarily stopped before being loaded on the processing table. By the temporal stop, the temperature difference between the substrate and the processing table becomes smaller. When the temperature difference becomes smaller, even if the substrate expands due to heat from the processing table, the degree of the change becomes smaller and therefore it is possible to reduce peeling of films deposited on the substrate-loading surface of the processing table.Type: GrantFiled: March 5, 2001Date of Patent: September 28, 2004Assignee: Anelva CorporationInventors: Shinichi Inaba, Yosuke Ide

Patent number: 6764304Abstract: A furnace design that combines the benefits of oxygen enriched combustion, intense flame radiation, highly preheated combustion air, exhaust gas recirculation, buoyancy driven flows and NOx reburn chemistry in a single unit to significantly reduce energy consumption and pollutant formation. The furnace also allows burning low calorie fuels and fuels of different types. It substantially increases the level of radiation heat transfer and its uniformity, thereby enhancing furnace productivity and provides an oxygen free atmosphere to prevent oxidation of materials being heated.Type: GrantFiled: October 31, 2002Date of Patent: July 20, 2004Assignee: The Regents of the University of MichiganInventor: Arvind Atreya

Publication number: 20040110106Abstract: A substrate processing apparatus is provided. When a wafer W held by a holding unit 35 is accommodated in a processing chamber 34a of a processing container 34 equipped with a heater 31A, the wafer W is heated to a processing temperature while positioning the wafer W at an adjacent position Pa resulting from making the wafer W approach the heating surface of the heater 31A, i.e. flat bottom surface of a container body 32. After heating the wafer W to the predetermined temperature, the wafer W is separated from the flat bottom surface of the container body 32 to a processing position Pb. In this state, a processing chamber 34a of the processing container 34 is supplied with a processing fluid, while the holding unit 35 and the heater 31A are relatively moved close to and apart from each other intermittently or continuously.Type: ApplicationFiled: December 3, 2003Publication date: June 10, 2004Inventor: Shori Mokuo

Patent number: 6746240Abstract: A support sleeve for supporting a high temperature process tube comprises one or more circumferential channels, each channel connected to either a feed for gas or a vacuum exhaust. One circumferential channel opens to the top surface of the sleeve, on which the process tube is supported to provide a gas/vacuum seal between the process tube and support sleeve. Another circumferential channel is connected to a gas feed and provided with gas injection holes, evenly distributed along the support sleeve perimeter to provide a cylindrically symmetrical injection of process gas into the process tube. Another circumferential channel is connected to an exhaust for gas and provided with gas exhaust holes, evenly distributed along the circumference of the support sleeve, to provide a cylindrically symmetric exhaust of process gases from the process tube.Type: GrantFiled: March 13, 2003Date of Patent: June 8, 2004Assignee: ASM International N.V.Inventors: Christianus Gerardus Maria De Ridder, Theodorus Gerardus Maria Oosterlaken, Frank Huussen

Patent number: 6746237Abstract: Method and device for the heat treatment of substrates, wherein the substrates are positioned in the vicinity of a heated, essentially flat furnace body extending over the surface of the substrate. In order to provide a reproducible treatment when treating a number of substrates successively, the temperature of the furnace body is measured so close to the surface adjacent to the substrate that the withdrawal of heat from the furnace body by the substrate can be detected. The introduction of each substrate takes place at a point in time when the temperature measured in this way is, within certain limits, equal to a desired initial treatment temperature Ttrig.Type: GrantFiled: May 16, 2002Date of Patent: June 8, 2004Assignee: ASM International N.V.Inventors: Arjen Storm, Ronald Bast, Vladimir Ivanovich Kuznetsov, Jan Zinger

Patent number: 6672864Abstract: A positive pressure gradient is maintained across an open access port of an interface chamber such as a load lock chamber which provides an interface between a low pressure chamber such as a transfer or buffer chamber, and a high pressure area such as a staging area or factory interface area. When the access port of the interface chamber is open to the high-pressure area, the positive pressure gradient may be used in some applications to inhibit the flow of gasses from the high-pressure area into the interior of the interface chamber.Type: GrantFiled: August 27, 2002Date of Patent: January 6, 2004Assignee: Applied Materials, Inc.Inventors: Hougong Wang, Zheng Xu, Kenny King-Tai Ngan
