Publication number: 20020117111Abstract: When a resist film is formed by discharging a resist solution onto the front face of a wafer housed in a cup, a relation between the film thickness of a resist film and the line width of a circuit pattern when the resist film is exposed into a predetermined pattern and thereafter developed is obtained in advance, from that relation, a line width with less variations corresponding to the changes in film thickness of the resist film is selected from among line widths within a designated region to form a resist film to have the film thickness corresponding to the selected line width. Accordingly, the line width of the circuit pattern after development is not likely to vary regardless of the changes in film thickness of the resist film formed on the wafer.Type: ApplicationFiled: April 30, 2002Publication date: August 29, 2002Inventor: Kosuke Yoshihara

Publication number: 20020112664Abstract: An automated priming system and method for applying a liquid, such as a primer or treatment liquid, to a substrate provides a surface variation sensitive applicator assembly which applies a constant pressure to the substrate during the liquid application process and, therefore, provides a process which achieves a more uniform application path and coating thickness. The automated system includes a robot and at least one applicator assembly. The applicator assembly includes a base and an applicator tip mounted to the base. The applicator tip is adapted to receive a supply of liquid. The robot holds the base of the applicator and positions the applicator tip on the substrate for applying a liquid onto the substrate. One of the applicator and the robot is adapted to apply a constant pressure to the substrate during the application process.Type: ApplicationFiled: April 26, 2002Publication date: August 22, 2002Applicant: Donnelly CorporationInventor: William A.

Patent number: 6402845Abstract: Methods of dispensing process liquid to provide a uniform layer of the liquid on a surface are disclosed in accordance with the present invention. The methods include dispensing a process liquid on the surface and rotating the surface at a first speed to distribute an effective amount of the process liquid to substantially wet the surface. The method further includes rotating the surface at a second speed to distribute an effective amount of the process liquid to produce a layer of the process liquid on the surface. In a preferred embodiment for dispensing photoresist onto the surface of a semiconductor wafer, the method includes rotating the wafer at the first speed prior to dispensing the photoresist onto the surface. The preferred method further includes decelerating the wafer from the first to the second speed during the dispensing of the photoresist and terminating the dispensing process after the second speed is reached.Type: GrantFiled: November 17, 2000Date of Patent: June 11, 2002Assignee: Micron Technology, Inc.Inventor: Paul Shirley

Patent number: 6402844Abstract: Process gas supply/stop operations are intermittently performed. As the hydrophobic process progresses, the temperature of a gas contract portion of a wafer lowers. While the hydrophobic process stops, the temperature of the gas contact portion of the wafer rises to the original temperature. Thereafter, the hydrophobic process resumes. Thus, while the temperature of the gas contact portion of wafer is suppressed from largely lowering, the hydrophobic process can be performed. Thus, non-uniformity of the hydrophobic process on the front surface of the wafer is reduced.Type: GrantFiled: September 8, 1999Date of Patent: June 11, 2002Assignee: Tokyo Electron LimitedInventors: Koji Harada, Ryoichi Uemura

Patent number: 6391111Abstract: To provide a coating apparatus which is capable of making short a lag time up to action of a valve and making operate a discharging pump and a valve with the best timing. By employing electric-air regulators ER1 and ER2 of small size and high response speed as a speed controller for controlling a switching speed of a switching valve AV or a suck-back valve SV, total flowing course is made short, thereby a time lag up to operation of a valve is made short. Further, by detecting the pressure of a resist liquid being discharged from a discharging pump 120 by a pressure sensor 123, and by controlling the operation of each device of a discharging pump 120, a switching valve AV, and a suck-back valve SV through a controller 180, a discharging pump 120, a switching valve AV, and a suck-back valve SV can be operated with the best timings, and generation of particles due to dripping of a resist liquid at a tip end of a resist nozzle 60 is prevented from occurring.Type: GrantFiled: January 15, 1999Date of Patent: May 21, 2002Assignee: Tokyo Electron LimitedInventors: Akihiro Fujimoto, Kazuo Sakamoto, Nobukazu Ishizaka, Izumi Hasegawa

Publication number: 20010054380Abstract: A system and method for controlling triggering of spray guns in an automatic spray coating system, includes a hand-held pendant having input controls for entering spray gun “on” and spray gun “off” control parameters based upon observation of parts as they are conveyed past the spray guns by a conveyor. Gun triggering controls for optimized spray patterns, including extended and restricted spray patterns and combinations thereof, are entered and saved in a gun triggering controller according to an operator's inputs which include START SPRAY, STOP SPRAY, SAVE and SET PICKOFF controls. Multiple gun control parameters are stored as unique part coating recipes in the controller and are executable in look-ahead sequence based upon part identification as parts are conveyed toward the spray guns. The multiple gun control parameters are calculated by the controller from a fixed Pickoff distance from a part identification sensor to the spray guns.Type: ApplicationFiled: August 21, 2001Publication date: December 27, 2001Inventors: Eric Coulibaly, Gene L.

Patent number: 6311620Abstract: While a transfer sheet 3 including a water-soluble base sheet on which a print layer is provided is floated on water, an adhesion is applied after the base sheet is dissolved, thereby to form a semi-fluidal print layer. An object is pressed against the print layer to achieve printing. In this technique, the present printing method and apparatus shorten the warm-up time required for dissolving the base sheet of the transfer sheet 3 to improve the working efficiency, and the transfer sheet 3 is previously cut at a predetermined length and is then floated on the water surface 5, so that wasteful consumption of the transfer sheet is reduced. The bottom of a water tank 11 is formed to be shallow in the left side than in the right side, so that the amount of water contained in the water tank 11 is reduced to shorten the warm-up time.Type: GrantFiled: January 20, 2000Date of Patent: November 6, 2001Assignee: Katsuya Industrial Col, Ltd.Inventor: Toshio Ogisu
