  • Publication number: 20190115194
    Abstract: The present invention relates to a substrate supporting member and a substrate processing method. A gas flow path supplying a heat transfer gas to a rear surface of a substrate is provided in the substrate supporting member according to an embodiment of the present invention. Furthermore, a gas flow restricting member restricting gas flow to a different extent from each other according to a direction of the gas flow is provided at the gas flow path or at an external heat transfer gas supply pipe connected to the gas flow path. According to the present invention, by providing the gas flow restricting member restricting the gas flow to a different extent from each other according to the direction of the gas flow, there are effects of minimizing the time required for exhausting the heat transfer gas while preventing the arcing from occurring in a heat transfer gas flow path.
