  • Publication number: 20240189856
    Abstract: A substrate processing apparatus that forms a friction reducing film on a rear surface of a substrate includes a processing container configured to accommodate the substrate and to define a hermetically-sealed processing space, a heating element configured to heat the rear surface of the substrate inside the processing container, a supplier configured to supply a material forming the friction reducing film toward the rear surface of the substrate inside the processing container, a first gas supplier configured to supply an inert gas to a peripheral edge of the substrate from a space above the substrate, a second gas supplier configured to supply the inert gas closer to a center of the substrate than the first gas supplier from a space above the substrate inside the processing, and an exhauster configured to exhaust an atmosphere of the processing space from a periphery or a space below the substrate.

  • Patent number: 11842906
    Abstract: A side surface unit of a heat treatment space S is formed by a shutter member 250 including an outer shutter 260 and an inner shutter 270. Supply air A is supplied as a horizontal laminar flow toward a wafer W from a lower end side of the shutter member 250, that is, from a gap d1 located on the level with the wafer W placed on a heat plate 211 of a mounting table 210. Supply air B is supplied into the heat treatment space S from an upper end side of the shutter member 250, that is, from a gap d2 positioned higher than the wafer W. A ratio between a flow rate of the supply air A and a flow rate of the supply air B is 4:1.
    Type: Grant
