  • Patent number: 9777364
    Abstract: An organic layer deposition apparatus, and a method of manufacturing an organic light-emitting display device using the organic layer deposition apparatus. The organic layer deposition apparatus includes: an electrostatic chuck that fixedly supports a substrate that is a deposition target; a deposition unit including a chamber maintained at a vacuum and an organic layer deposition assembly for depositing an organic layer on the substrate fixedly supported by the electrostatic chuck; and a first conveyor unit for moving the electrostatic chuck fixedly supporting the substrate into the deposition unit, wherein the first conveyor unit passes through inside the chamber, and the first conveyor unit includes a guide unit having a receiving member for supporting the electrostatic chuck to be movable in a direction.

  • Patent number: 8951610
    Abstract: An organic layer deposition apparatus that may be precisely aligned with a substrate during a deposition process. The apparatus includes: a deposition source; a deposition source nozzle unit; and a patterning slit sheet, which is spaced from and smaller than the substrate, and having a plurality of patterning slits arranged in a second direction perpendicular to the first direction. Deposition is performed while the substrate is moved relative to the deposition apparatus in the first direction. The patterning slit sheet includes first and second alignment marks that are spaced from each other. The substrate includes first and second alignment patterns that are spaced from each other. The deposition apparatus also includes first and second camera assemblies for respectively photographing the first alignment mark/pattern and the second alignment mark/pattern. A moving speed of the substrate is synchronized with shooting speeds of the first and second camera assemblies.
