  • Patent number: 7965372
    Abstract: A photoresist film removing apparatus includes a reacting chamber, an ozonizer producing a gas supplied to the reacting chamber, and an exhaust system that exhausts the gas from the reacting chamber. A source of a photoresist film-remover is located opposite a stage carrying a substrate covered with photoresist. Photoresist film-remover and the gas are supplied to the substrate through apertures. An electric field may be generated between the source of the photoresist film-remover and the substrate. Alternatively, a centrally located feed tube supplies only one of the gas and the photoresist film-remover through a single aperture and a reservoir discharges the other through apertures. The reservoir surrounds and is sealed to the feed tube. The apparatus may include a container holding a liquid photoresist film-remover and a mixture of the gas and remover is supplied from outside the reacting chamber to the substrate.

  • Publication number: 20110128512
    Abstract: A scatterometer, configured to measure a property of a substrate, includes a radiation source which produces a radiation spot on a target formed on the surface of the substrate, the size of the radiation spot being smaller than the target in one direction along the target, the position of the radiation spot being moved along the surface in a series of discrete steps. A detector detects a spectrum of the radiation beam reflected from the target and produces measurement signals representative of the spectrum corresponding to each position of the radiation spot. A processor processes the measurement signals produced by the detector corresponding to each position of the radiation spot and derives a single value for the property.

  • Publication number: 20110096304
    Abstract: A pretreatment process, carried out prior to a developing process, spouts pure water, namely, a diffusion-assisting liquid for assisting the spread of a developer over the surface of a wafer, through a cleaning liquid spouting nozzle onto a central part of the wafer to form a puddle of pure water. The developer is spouted onto the central part of the wafer for prewetting while the wafer is rotated at a high rotating speed to spread the developer over the surface of the wafer. The developer dissolves the resist film partly and produces a solution. The rotation of the wafer is reversed, for example, within 7 s in which the solution is being produced to reduce the water-repellency of the wafer by spreading the solution over the entire surface of the wafer. Then, the developer is spouted onto the rotating wafer to spread the developer on the surface of the wafer.

Substrates on which films have been formed by the first and the second processing block are collected temporarily in the transfer block. A second direct carrying means carries the substrate collected in the transfer block from the transfer block to an interface block. Use of the first and the second processing block can improve the throughput of the coating and developing system. Since a carrying route from the carrier block to the first processing block, and a carrying route from the carrier block to the second processing block are the same, a carrying program is easy to create.

  • Patent number: 7742146
    Abstract: A resist film formed on a substrate is coated with a water-repellent protective film and the substrate is subjected to a developing process after the substrate has been processed by an immersion exposure process. The protective film is removed from the substrate after the resist film has been processed by the immersion exposure process, the substrate is processed by a heating process, and then the substrate is subjected to a developing process. The surface of the substrate is cleaned with a cleaning liquid before the protective film is removed and after the substrate has been processed by the immersion exposure process or the surface of the substrate is cleaned with a cleaning liquid after removing the protective film and before the substrate is subjected to the heating process.

  • Patent number: 7714979
    Abstract: 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.

  • Patent number: 7692764
    Abstract: 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.

  • Patent number: 7661894
    Abstract: 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.
