Patent number: 5805856Abstract: A heating system includes an electric heater having coupled thereto a temperature controller and a power activation relay switch coupled to the temperature controller and a meter system coupled to a power terminal on the electric heater to provide an interruptible supplemental heating system for use in residential or commercial buildings. The heating system provides electrically generated heat to supplement a primary heating system which generates heat using fuel oil, fuel gas such as natural gas, propane gas, or other fossil fuels. The electric heater can be an electric resistance heater coupled in series with a primary furnace powered by fossil fuel. When the electric resistance heater is activated, the heat contributed by the heater reduces the required heat output of the primary furnace by a corresponding amount of thermal energy. In one embodiment, an electric utility provides electric power to the electric resistance heater at a reduced cost on an as available, fully interruptible basis.Type: GrantFiled: May 3, 1996Date of Patent: September 8, 1998Assignee: Jeffrey H.

Patent number: 5790751Abstract: A rapid thermal heating apparatus in which lamps are disposed in a plurality of light pipes arranged to illuminate and supply heat to a substrate. The light pipes are positioned so that the illumination patterns overlap. The energy supplied to the lamps is controlled to provide a predetermined heating pattern to the substrate. A liquid cooled window cooperates with the light pipes to transmit energy to a wafer disposed in an evacuated chamber.Type: GrantFiled: January 13, 1997Date of Patent: August 4, 1998Assignee: Applied Materials, Inc.Inventors: Christian M. Gronet, James F. Gibbons

Patent number: 5767486Abstract: A rapid thermal heating apparatus including an evacuable chamber having a window, a plurality of radiant energy sources and reflectors associated with the radiant energy sources. The radiant energy sources are disposed outside of the chamber and positioned adjacent to the window. They have a central longitudinal axis that extends in a substantially perpendicular direction relative to the window. The reflectors direct radiant energy through the window to radiate predetermined regions of a backside surface of a substrate in the chamber. The reflectors extend along a major portion of the longitudinal axis of the radiant energy sources. The substrate sits on a support in the chamber, and a source of processing gas, including a gas inlet manifold, is provided for passing processing gas to a frontside surface of the substrate.Type: GrantFiled: January 13, 1997Date of Patent: June 16, 1998Assignee: Applied Materials, Inc.Inventors: Christian M. Gronet, James F. Gibbons

Patent number: 5751897Abstract: A system for safely removing even a hazardous contaminant from a substrate surface includes a light energy source whose output is controlled to selectively provide components primarily in the visible and infrared spectrum, and a power unit for energizing the light energy source at a desired energy level, pulse width and pulse repetition rate. Proper selection of these parameters permits the energy source to heat the contaminant sufficiently to cause direct carbonization without entering a melt phase, without the need for any precoat medium. Because the resultant molecular decomposition of the contaminant occurs relatively faster than heat transfer to the underlying substrate, substantially no substrate heating results. The light source energy transforms the contaminant to an ash that is removed from the substrate by a vacuum system preferably surrounding the light source. The light source is preferably a xenon flash lamp operated with a pulse repetition rate of between about 0.Type: GrantFiled: November 12, 1996Date of Patent: May 12, 1998Inventor: David C. Van Alstyne

Patent number: 5659657Abstract: A heater element support frame is pivotally mounted at one edge to a support member attached to a reflector for movement between a first position disposing the frame adjacent to the reflector and a second position in which the frame is spaced from the reflector. Heater element end caps are slidably mounted in slots formed in sidewalls of the frame and mountable in a selectively adjustable position along the slots. Alternately, slots are formed in the reflector and arranged in a dimensional relationship to receive the end cap mounts such that the ends of two adjacent alternating heater elements of two side-by-side arranged columns of heater elements are offset from each other such that the heat generating portion of one heater element overlaps a non-heat generating portion and the end cap of an adjacent heater element.Type: GrantFiled: May 24, 1995Date of Patent: August 19, 1997Assignee: Brokaw, Inc.Inventor: Joel R. Overdorf
