  • Patent number: 9805938
    Abstract: A substrate processing apparatus includes a rotating holder for a substrate, a first nozzle used to eject a jet flow, a second nozzle used to discharge a continuous flow, and a nozzle moving unit integrally moving the first and second nozzles. A landing position of the continuous flow is located closer to a rotation center than a landing position of the jet flow is. At least movement paths of the landing positions of the jet flow and the continuous flow or flow directions of the continuous flow and the jet flow are different from each other. The movement paths are made to be different from each other by locating the landing position of the continuous flow downstream of the movement path of the landing position of the jet flow. The flow directions are made to be different from each other by tilting the continuous flow.

  • Patent number: 9793176
    Abstract: The temperature of a chemical liquid supplied to a pot is detected while allowing a processing liquid discharge port to discharge the chemical liquid toward the pot at a pre-dispensing position. The temperature of the chemical liquid rises in response to the lapse of time. When the temperature of the chemical liquid supplied to the pot reaches a second target temperature, the processing liquid discharge port is allowed to stop the discharge of the chemical liquid. Thereafter, a positional relationship between the processing liquid discharge port and the pot is changed, and the processing liquid discharge port is allowed to discharge the chemical liquid toward the substrate at the processing position.

  • Publication number: 20160240399
    Abstract: A supply flow passage branches into a plurality of upstream flow passages. A plurality of discharge ports are respectively disposed at a plurality of positions differing in distance from a rotational axis of a substrate. Hydrogen peroxide water, that is one of components of a chemical liquid (SPM), is supplied to the upstream flow passage from a component liquid flow passage.
