  • Patent number: 9004788
    Abstract: 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.

  • Patent number: 8398319
    Abstract: A developing apparatus including a substrate holder that holds a substrate horizontally; means for atomizing a surface treatment liquid used to improve wettability of the substrate with a developer; a first spray nozzle that sprays the atomized surface treatment liquid onto the substrate; and a developer supply nozzle that supplies a developer onto the substrate to which the substrate treatment liquid has been sprayed. The surface tension of the atomized surface treatment liquid with respect to the substrate is lower than the surface tension of the surface treatment liquid with respect to the substrate. The atomization suppresses the fact that the surface treatment liquid gathers on a certain portion of the surface of the substrate. The surface treatment liquid can be easily supplied onto the entire surface of the substrate, and improve wettability of the substrate with the developer.
