Abstract:
PURPOSE: A laser irradiation apparatus is provided to effectively improve treatment quantity per hour without changing the total amount of energy of oscillation laser light. CONSTITUTION: Laser lights(LB1,LB2) are irradiated on a semiconductor layer(SC) which is formed on a substrate(SS) according to a scan direction(SL). The semiconductor layer comprises a plurality of pixel regions. A laser generator(910) comprises a first laser generator(911) which oscillates first laser light and a second laser generator(912) which oscillates second laser light. The first laser light and the second laser light are partitioned and are respectively irradiated toward a plurality of laser masks(610,620). A plurality of laser masks comprises a plurality of slit groups(615).
Abstract:
A laser irradiation apparatus provides a laser beam along a scan direction to a semiconductor layer including a plurality of pixel areas. The laser irradiation apparatus includes at least one laser mask including a plurality of slit groups respectively facing portions of the plurality of pixel areas and a laser generator generating the laser beam that pass through the plurality of slit groups of the at least one laser mask.
Abstract:
PURPOSE: A laser crystallization device and a method thereof are provided to enable the crystallization of a thin film on a substrate since a laser beam is scanned on the substrate in a specific direction. CONSTITUTION: A laser beam irradiation unit(110) scans laser beam on a substrate in a specific direction. A stage(120) arranges the substrate. A fixing unit(130) is formed on the stage to correspond to one edge of the substrate. A driving unit(150) lifts one side of the stage so the area in which the fixing unit is placed is moved down. The substrate is moved by the gravity and is mounted in the fixing unit.
