Patent number: 8479683Abstract: A method of forming a boron nitride or boron carbon nitride dielectric produces a conformal layer without loading effect. The dielectric layer is formed by chemical vapor deposition (CVD) of a boron-containing film on a substrate, at least a portion of the deposition being conducted without plasma, and then exposing the deposited boron-containing film to a plasma. The CVD component dominates the deposition process, producing a conformal film without loading effect. The dielectric is ashable, and can be removed with a hydrogen plasma without impacting surrounding materials. The dielectric has a much lower wet etch rate compared to other front end spacer or hard mask materials such as silicon oxide or silicon nitride, and has a relatively low dielectric constant, much lower then silicon nitride.Type: GrantFiled: September 13, 2012Date of Patent: July 9, 2013Assignee: Novellus Systems, Inc.Inventors: George Andrew Antonelli, Mandyam Sriram, Vishwanathan Rangarajan, Pramod Subramonium

Method for treating and/or coating the surface of substrate components. The procedure comprises: a) compiling coating and/or treating units and shielding elements from modules in the deposition or treatment chamber; b) equipping the substrate carriers with those substrate components that are to be subjected to the same treatment; c) closing the deposition or treatment chamber; and d) carrying out the individual treatment or coating programs for the substrate components combined in groups on the substrate carriers in one batch.Type: ApplicationFiled: May 10, 2011Publication date: December 15, 2011Applicant: GUEHRING OHGInventor: Mario Fiedler

Publication number: 20110297085Abstract: A substrate processing apparatus is disclosed equipped with a transfer mechanism that transfers a substrate processed at a processing block to a carrier so that the increase of the number of transfer process is suppressed, improving the processing efficiency. The substrate processing apparatus is configured in such a way that, when a second-transfer module houses at least one substrate and a carrier that can house the at least one substrate is not placed in a carrier-placement unit, the at least one substrate is transferred to a buffer module. When the second transfer module houses at least one substrate and the carrier that can house the at least one substrate is placed in the carrier-placement unit, the at least one substrate is transferred to the carrier, regardless of whether or not a substrate is being transferred from the buffer module to the carrier.Type: ApplicationFiled: June 8, 2010Publication date: December 8, 2011Applicant: TOKYO ELECTRON LIMITEDInventors: Kenichirou MATSUYAMA, Tomohiro KANEKO

Patent number: 8037844Abstract: Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to make selections or changes of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections or changes without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation. The display may include numeric information, for example, data relating to a coating function being displayed.Type: GrantFiled: October 31, 2007Date of Patent: October 18, 2011Assignee: Nordson CorporationInventors: Brian Mather, Jeffrey A.

Publication number: 20110239936Abstract: A process for producing a semiconductor device, comprising the steps of conducting film formation on substrate (10) in reactor (1); and unloading the substrate (10) after film formation from the reactor (1) and thereafter effecting forced air cooling of the interior of the reactor (1) while the substrate (10) is absent in the reactor (1). The stress of deposited film adhering in the reactor (1) is increased over that exhibited at air cooling without blower so as to positively generate thermal stress with the result that the deposited film would undergo forced cracking over that exhibited at air cooling without blower. Microparticles scattered by the cracking are efficiently discharged from the reactor forcibly through purging in the reactor in the state of atmospheric pressure.Type: ApplicationFiled: May 2, 2011Publication date: October 6, 2011Inventors: Kenichi SUZAKI, Jie WANG

Publication number: 20110217467Abstract: A vacuum processing apparatus includes two process chambers and three load-lock chambers which are alternately connected in series, and a transferring device which transfers a plurality of carriers only between the process chamber and the load-lock chambers that are adjacent to each other. A substrate undergoes deposition processing when the carrier is positioned in the process chamber by the transferring device, and the substrate is replaced when the carrier is positioned in the load-lock chamber by the transferring device.Type: ApplicationFiled: March 1, 2011Publication date: September 8, 2011Applicant: CANON ANELVA CORPORATIONInventors: Hajime SAHASE, Naoki Watanabe, Ge Xu

Publication number: 20110200747Abstract: A manufacturing machine for manufacturing a wrapping paper web for cigarettes with a low ignition propensity has a coating device (3) at a coating position defined in a travel path (2) of web (W). The coating device (3) has a rotary screen (4) and a gravure roller (6) located on the opposite sides of the travel path (2) and functioning as back rollers for each other. The rotary screen (4) intermittently applies a liquid burning inhibitor onto one side of the web (W) to form a number of band layers (B) arranged at predetermined intervals in a travelling direction of the web (W), and the gravure roller (6) applies water onto the other side of the web (W) to form wet bands (A) arranged alternately with the band layers (B) in the traveling direction of the web (W).Type: ApplicationFiled: April 26, 2011Publication date: August 18, 2011Inventors: Shinzo Kida, Takafumi Izumiya, Yuzuru Sakuma, Yasumasa Tominaga, Hiroyuki Nakashima

Patent number: 7934467Abstract: An apparatus and method of preparing and coating a large structure such as a ship's hull while in a dry dock wherein a plurality of spray guns disposed in an array are positioned by a robotic arm in a spaced relationship along the surface to be treated so that their spray patterns overlap. The array of spray guns is traversed downwardly a thus painting a strip whereupon the spray guns are secured, move horizontally and then activated to be moved upwardly until another strip adjacent to and overlapping the first strip is painted. These steps are repeated until the surface area is substantially entirely painted. A shroud is provided for collecting paint oversprays and other excess paint is mounted in the array assemblage. An auxiliary spray gun may be positioned and its spray pattern adjusted to apply paint to areas which were missed by the original spray pattern emanating from the array of spray guns.Type: GrantFiled: February 1, 2005Date of Patent: May 3, 2011Inventor: John Stephen Morton

Patent number: 7890220Abstract: A tool includes a chamber, a network, a sensor, a tool controller, and a pressure controller. The network carries messages to and from devices on the network. A header portion of a message indicates a sender of the message and at least one intended recipient of the message. The sensor measures a pressure within the chamber. The sensor, tool controller, and pressure controller are on the network. The pressure controller controls the pressure within the chamber in response to measurements provided by the sensor and in response to a set point provided by the tool controller. The pressure controller processes header portions of all messages carried on the network to determine the intended recipients of each message and processes at least part of data portions of both messages intended for the pressure controller and at least some messages not intended for the pressure controller.Type: GrantFiled: May 3, 2005Date of Patent: February 15, 2011Assignee: MKS Instruments, Inc.Inventor: David Brian Chamberlain
