Patent number: 8888917Abstract: A vapor deposition reactor and associated method are disclosed that increase the lifetime and productivity of a filament-based resistive-heated vapor deposition system. The reactor and method provide for heating the filament while permitting the filament to move as it expands under the effect of increasing temperature while limiting the expanding movement of the filament to an amount that prevents the expanding movement of the filament from creating undesired contact with any portions of the reactor.Type: GrantFiled: January 4, 2010Date of Patent: November 18, 2014Assignee: Cree, Inc.Inventors: David Todd Emerson, Robert Allen Garner, Michael John Bergmann, Keenan Carlyle Brown, Michael Allen Pennington, Thomas Goldthwaite Coleman

Publication number: 20140332161Abstract: An apparatus for control of a temperature of a substrate has a temperature-controlled base, a heater, a metal plate, a layer of dielectric material. The heater is thermally coupled to an underside of the metal plate while being electrically insulated from the metal plate. A first layer of adhesive material bonds the metal plate and the heater to the top surface of the temperature controlled base. This adhesive layer is mechanically flexible, and possesses physical properties designed to balance the thermal energy of the heaters and an external process to provide a desired temperature pattern on the surface of the apparatus. A second layer of adhesive material bonds the layer of dielectric material to a top surface of the metal plate. This second adhesive layer possesses physical properties designed to transfer the desired temperature pattern to the surface of the apparatus.Type: ApplicationFiled: July 24, 2014Publication date: November 13, 2014Inventors: Anthony J.

Patent number: 8864933Abstract: In a substrate treatment method for supplying a coating solution to a substrate with projections and depressions on a front surface thereof to form a coating film on the front surface of the substrate, the coating solution is supplied to the rotating substrate to form a coating film on the front surface of the substrate, and the substrate having the coating film formed thereon is heated to adjust an etching condition of the coating film. Next, the etching solution is supplied to the rotating substrate to etch the coating film, and thereafter the coating solution is supplied to the substrate to form a flat coating film on the front surface of the substrate. Thereafter, the substrate is heated to cure the coating film. This flattens the coating film with uniformity and high accuracy without undergoing a high-load process such as chemical mechanical polishing.Type: GrantFiled: October 20, 2010Date of Patent: October 21, 2014Assignee: Tokyo Electron LimitedInventors: Shouichi Terada, Tsuyoshi Mizuno, Takeshi Uehara

Patent number: 8864934Abstract: Provided is a parallel flat-panel type plasma processing apparatus which includes a recipe storing unit storing a processing recipe for performing a plasma processing, a compensation setting unit setting an accumulation time of the plasma processing or the number of processed substrates after starting using a new second electrode and the compensation value of the set temperature of the second electrode in an input screen, and a storage unit storing the compensated set value. The plasma processing apparatus is further equipped with a program for controlling a temperature adjusting mechanism based on a set temperature after compensation by adding a set temperature of an upper electrode written in the processing recipe to the compensation value stored within the storage unit. As a result, the non-uniformity in the plasma processing between the substrates caused by the change of processing atmosphere is suppressed.Type: GrantFiled: March 29, 2012Date of Patent: October 21, 2014Assignee: Tokyo Electron LimitedInventors: Tatsuya Ogi, Wataru Ozawa, Kimihiro Fukasawa, Kazuhiro Kanaya

Patent number: 8858715Abstract: The invention relates to a deposition device for comprising a processing space with a substrate support disposed therein, as well as several lift pins (50), which can be moved into and out of the plane of the substrate support to assist in introducing a semiconductor substrate into the processing space and removing it therefrom. The device is characterized in that the contact surface (52) of the lift pin (50) that is to be brought into contact with the semiconductor substrate and/or the substrate support is provided with a material layer (54) which has a lower hardness than the semiconductor substrate and/or the substrate support. This eliminates the risk of damage being caused to the substrate and/or to the substrate support as a result of said substrate shifting undesirably upon being lifted from and lowered onto the substrate support (susceptor). Thus there is no risk of scratches being formed and of particles being released, which might adversely affect the semiconductor manufacturing process.Type: GrantFiled: September 19, 2008Date of Patent: October 14, 2014Assignee: XYCarb Ceramics B.V.Inventors: Marcus Gerardus Van Munster, Charles Petronella Marie Buijs, Age Leijenaar
