  • Patent number: 6875280
    Abstract: A substrate processing apparatus includes a chamber, a gas introducing portion, a gas discharge port, a substrate transfer gate, and a substrate moving member which moves the substrate between a substrate processing position where the substrate is processed in the chamber and a substrate transferring in-out position in the chamber where the substrate transferred into the chamber from the substrate transfer gate is located and where the substrate is located when the substrate is transferred out from the chamber through the substrate transfer gate. The gas introducing portion, the substrate processing position, the gas discharge port and the substrate transfer gate are disposed in this order. A gas restraining member which restrains processing gas for processing the substrate from flowing toward the substrate transfer gate is provided between the gas discharge port and the substrate transfer gate.
