Patent number: 8222569Abstract: A heat treating apparatus utilizes a straightening plate provided in its central part with a gas exhaust opening and disposed under a heating plate. A temperature-reducing purge ring is disposed between the face plate and the straightening plate, and is provided in its inner circumference with plural gas jetting holes. A thin gap is formed between the temperature-reducing purge ring and the face plate. When a cooling gas is jetted radially inward through the gas jetting holes, a vacuum is created between the lower surface of the face plate and the upper surface of the temperature-reducing purge ring. Air is sucked into the space between the face plate and the straightening plate and flows together with the cooling gas to rapidly cool the face plate.Type: GrantFiled: October 3, 2008Date of Patent: July 17, 2012Assignee: Tokyo Electron LimitedInventors: Yuichi Sakai, Kiyomitsu Yamaguchi

Publication number: 20090098297Abstract: A straightening plate provided in its central part with a gas exhaust opening is disposed under a face plate serving as a heating plate. A temperature-reducing purge ring is disposed between the face plate and the straightening plate. The temperature-reducing purge ring has an outside diameter substantially equal to that of the straightening plate and is provided in its inner circumference with plural gas jetting holes. The temperature-reducing purge ring is disposed close to the face plate such that a thin gap is formed between the temperature-reducing purge ring and the face plate. When a cooling gas is jetted radially inward through the gas jetting holes of the temperature-reducing purge ring, a vacuum is created between the lower surface of the face plate and the upper surface of the temperature-reducing purge ring.Type: ApplicationFiled: October 3, 2008Publication date: April 16, 2009Applicant: TOKYO ELECTRON LIMITEDInventors: Yuichi SAKAI, Kiyomitsu Yamaguchi

Patent number: 6770149Abstract: A method for a cleaning treatment including a step of forming, in a coating mechanism, a coating film on a substrate provided within a cup. The method further includes dissolving, in an edge cleaning mechanism, a portion of the coating film on the substrate using a cleaning liquid, and recovering at least a portion of used cleaning liquid from the edge cleaning mechanism. The recovered cleaning liquid is stored and a level of the stored cleaning liquid is detected. The method also includes supplementing a fresh cleaning liquid to the stored cleaning liquid when a detected level of the stored cleaning liquid is lower than a predetermined level, and using a mixture of the supplemented fresh cleaning liquid and the stored cleaning liquid to clean the cup of the coating mechanism.Type: GrantFiled: April 23, 2002Date of Patent: August 3, 2004Assignee: Tokyo Electron LimitedInventors: Fumio Satou, Mitsuhiro Sakai, Takeshi Tsukamoto, Yoichi Honda, Kiyomitsu Yamaguchi

Patent number: 6062240Abstract: A treatment device comprising a holding method for holding a substrate such as an LCD substrate; and a treatment solution supply method for supplying a treatment solution on a surface of the substrate wherein the holding method has a substrate-placing portion on which the substrate is disposed, the substrate-placing is made of a synthetic resinous material. Since the holding method has a substrate-placing portion which is made of a synthetic resinous material, the electric charge amount of the substrate can be reduced to prevent various static electricity caused troubles such as the electrostatic destruction of the device formed on the substrate. Further, a discharge noise trouble due to discharge phenomenon from the substrate to a transporting method can be prevented. Further, it is possible to reduce the electric charge amount of the holding method and destaticize the holding method by supplying a destaticizing fluid such as ionized pure water or ionized gas towards above or below the holding method.Type: GrantFiled: March 6, 1998Date of Patent: May 16, 2000Assignee: Tokyo Electron LimitedInventors: Tetsuya Sada, Norio Uchihira, Mitsuhiro Sakai, Kiyomitsu Yamaguchi

Patent number: 5945161Abstract: Disclosed is a processing apparatus comprising holding means, support means, process solution supply means, life means, and rotating means. A substrate to be processed is rotatably held by the holding means. An overhanging portion of the substrate extending over an edge of the holding means is supported by the support means to maintain a front surface of the substrate horizontally flat. A process solution is supplied from the process solution supply means onto the front surface of the substrate held by the holding means and supported by the support means. The substrate held by the holding means is vertically moved by the lift means relative to the support means. Further, the substrate moved upward relative to the support means is rotated by the rotating means.Type: GrantFiled: December 18, 1997Date of Patent: August 31, 1999Assignee: Tokyo Electron LimitedInventors: Hiroshi Hashimoto, Kiyohisa Tateyama, Kiyomitsu Yamaguchi, Yoshitaka Matsuda, Norio Uchihira, Mitsuhiro Sakai, Fumio Satou
