Patent number: 7714979Abstract: A substrate processing apparatus enables an efficient collection of a solvent vapor discharged via a nozzle onto a wafer on which a resist pattern is formed. A retaining base that retains the wafer is moved relative to the nozzle, which includes a nozzle head. A pair of leakage preventing portions are disposed opposite to each other across the nozzle head. Each of the leakage preventing portions has an opening via which the solvent vapor discharged out of the discharge opening can be sucked, or a solvent vapor blocking gas can be discharged selectively. A solvent vapor supply source and a gas supply source are switchably connected to the supply opening of the nozzle head via a first switching valve. An exhaust pump and a solvent-vapor-blocking gas supply source are switchably connected to the openings of the leakage preventing portions via a second switching valve.Type: GrantFiled: October 14, 2008Date of Patent: May 11, 2010Assignee: Tokyo Electron LimitedInventors: Taro Yamamoto, Hideo Funakoshi, Yuichiro Inatomi

Patent number: 7692764Abstract: An exposure apparatus is equipped with a main controller that decides an operation of the exposure apparatus based on information on maintenance from a C/D. Therefore, the main controller can decide to perform a specific operation, which is necessary for maintaining performance of the exposure apparatus and requires stop of the primary operation of the exposure apparatus, during maintenance of the C/D, that is, when the primary operation of the exposure apparatus has to be stopped by necessity, in parallel with the maintenance of the C/D. As a consequence, downtime of the exposure apparatus necessary for performing the specific operation can be decreased as a whole, which makes it possible to improve the operating rate without lowering apparatus performance of the exposure apparatus that is inline connected to a substrate processing apparatus.Type: GrantFiled: August 29, 2005Date of Patent: April 6, 2010Assignee: Nikon CorporationInventor: Yousuke Shirata

Patent number: 7661894Abstract: A processing block S2 includes unit blocks, a BCT layer B3, COT layer B4 and TCT layer B5, for forming coating films, and further includes DEV layers B1, B2 layered with the unit blocks B3, B4, B5 and used as unit blocks for a developing process. Beside the unit blocks B1 to B5, a group G of transfer sections comprising transfer sections adapted to transfer each wafer W with each main arm A1 to A5 of the unit block B1 to B5 and hydrophobicity rendering units adapted to provide a hydrophobicity rendering process to the wafer W is provided. The wafer W is transferred by a transfer arm D between the transfer sections and the hydrophobicity rendering units. In this case, since it is not necessary to transfer the wafer W to the hydrophobicity rendering unit by using, for example, a main arm A4 of a COT layer B4, the load on the arm A4 can be reduced, thereby enhancing the carrying throughput.Type: GrantFiled: September 19, 2006Date of Patent: February 16, 2010Assignee: Tokyo Electron LimitedInventors: Nobuaki Matsuoka, Mitsuhiro Tanoue, Shinji Okada
