  • Patent number: 8940365
    Abstract: A device to form a coating film which can quickly coat a substrate of a follow-up lot after coating a preceding lot. The device is configured such that nozzles for a preceding lot and a following lot are integrated into a common movement mechanism and moved between an upper side of a liquid processing unit and a standby area. A coating method includes sucking air into the nozzle for the preceding lot to form an upper gas layer, sucking a solvent for the preceding lot in the standby area to form a thinner layer, and sucking air into the nozzle for the preceding lot to form a lower gas layer within the nozzle, and thus forming a state that a solvent layer is interposed between the upper gas layer and the lower gas layer.

  • Patent number: 8722152
    Abstract: A wet processing apparatus for wet-processing substrates can suppress the reduction of throughput when some component part thereof becomes unserviceable. The wet processing apparatus includes a first nozzle unit and a second nozzle unit. When the wet processing apparatus operates in a normal mode, a substrate carrying mechanism is controlled so as to deliver substrates alternately to processing units of a first group and those of a second group so that the substrates are processed sequentially in order. When the processing units of the first group (the second group) are unserviceable due to the inoperativeness of the substrate holders, a processing liquid supply system or a nozzle support mechanism, the nozzle unit for the processing units of the second group (the first group) is moved to process substrates by the serviceable ones of the first group (the second group).
