  • ATMOSPHERE STABILIZATION METHOD AND LASER PROCESSING APPARATUS
    Publication number: 20120236896
    Abstract: Disruption of a gas atmosphere does not occur when a substrate is rotated 90° after it is carried into a laser processing apparatus. The substrate is carried such that a gas ejection port is positioned near a midportion of a first side of the substrate. The substrate is linearly moved to bring a center of the substrate near the gas ejection port and the substrate is horizontally rotated 90° about the center thereof. Because an edge portion of the gas ejection port does not go beyond a seal cover during rotation, disruption of the gas atmosphere that occurs due to the escaping of the gas does not occur.
