  • Publication number: 20120266925
    Abstract: Provided is a processing apparatus for performing a processing of a substrate to be processed using a high-pressure fluid to prevent the generation of particles and ensure airtightness in the processing container. A sealing member is installed to surround a carrying port of the processing chamber, the carrying port is closed by the cover, and the cover is restricted from retreating by the pressure in the processing chamber by a lock plate, thereby processing the wafer in the processing chamber using the high-pressure fluid. Since the sealing member is pressurized by the internal atmosphere of the processing chamber to be pressed toward the cover during the drying process, a gap between the cover and the processing chamber may be airtightly closed. Since the sealing member does not slide with respect to the processing chamber or the cover, the generation of particles is suppressed.

  • Patent number: 8266820
    Abstract: A substrate processing method which can reduce the number of particles to be left on each substrate is provided. In the substrate processing method, substrates W to be processed are dried, by using a fluid heated by a heating apparatus having one or more heating mechanisms. The substrate processing method comprises a first step of supplying a mixed fluid containing a gas and a processing liquid and heated by the heating apparatus, into a processing chamber in which the substrates to be processed are placed, and a second step of supplying the heated gas into the processing chamber. The output of at least one of the heating mechanisms is kept at a preset constant value for a period of time during which a predetermined time passes after the start of the first step. In the second step, the output of the heating mechanism is determined under a feed back control.
