  • Publication number: 20240030049
    Abstract: A substrate processing apparatus includes: a heat processing unit configured to perform a heat process on a substrate having a film formed on the substrate; and a control unit configured to control the heat processing unit, wherein the heat processing unit comprises: a heater configured to support and heat the substrate; a chamber configured to cover the substrate supported on the heater; a gas ejector having a head in which ejection holes are formed, and configured to eject a gas from the ejection holes toward a surface of the substrate; an outer peripheral exhauster configured to evacuate a processing space inside the chamber from an outer peripheral region located further outward than a peripheral edge of the substrate supported on the heater; and a central exhauster configured to evacuate the processing space from a central region located further inward than the peripheral edge of the substrate supported on the heater.

  • Patent number: 11049758
    Abstract: A substrate can be placed on a placing table horizontally. When placing the substrate on the placing table having multiple protrusions configured to support the substrate, the substrate is attracted to the placing table while performing a suction from a suction hole configured to attract a position, different from positions located above the protrusions, of the substrate placed on the placing table, and then, a suction force of the suction hole is reduced. Accordingly, it is possible to place the substrate on the placing table while correcting the flexure. Further, the substrate can be horizontally placed on the placing table since deformation of the wafer, caused by attracting a bottom surface of the wafer strongly, is suppressed.

  • Publication number: 20190295864
    Abstract: A substrate processing apparatus includes: placing table on which a substrate to be processed is placed; suction mechanism including a pipe configured to apply a suction force to a rear surface of the substrate through one or a plurality of hole portions formed in the placing table to hold the substrate; and fluid supply source configured to discharge a fluid to one or a plurality of discharge portions formed in the placing table outward of the hole portions in the placing table and to form a horizontal airflow toward an outside of the substrate on a rear surface of the substrate.
