  • Patent number: 7993081
    Abstract: A device capable of causing a substrate to float by a gas can suppress the consumption of a gas. The device includes a carrying passage along which a substrate is carried. The gas spouted through the gas spouting pores causes the substrate to float and creates gas flows in the carrying gas flow grooves to propel the substrate in a carrying direction. The carrying passage is divided with respect to the carrying direction into passage sections, and the spouting of the gas through groups of the gas spouting pores assigned respectively to the passage sections is controlled to suporess the consumption of the gas.

  • Patent number: 7470098
    Abstract: An optical sensor for detecting the housing state such as the thickness of a substrate in the present invention is provided at supporting arms. The supporting arms are attached to a supporting shaft. The supporting arms are in a vertical state in a state before detection of the substrate, but when detecting, the supporting shaft rotates to bring the supporting arms into a horizontal state so that the optical sensor enters a substrate housing body and is set at a predetermined detection position. Accordingly, a space for moving the optical sensor in the horizontal direction becomes unnecessary to reduce the space required for the detecting operation and the like, making it possible to reduce the size of a substrate processing apparatus in which the detecting apparatus is incorporated.
