  • Patent number: 8048229
    Abstract: An apparatus for depositing an organic layer and a method for controlling the heating unit thereof are provided. The apparatus includes a crucible positioned in a deposition chamber and containing materials for evaporation. The apparatus also includes a heating unit having first and second heat sources for heating the crucible. A housing isolates the heat emitted from the heating unit and an outer wall anchors the crucible. A nozzle sprays the materials evaporated from the crucible. The first and second heat sources are positioned on first and second sides of the crucible, respectively, and are independently controlled to minimize the time required to stabilize the deposition rate.

  • Patent number: 7914621
    Abstract: A vapor deposition source has a reduced size by disposing a crucible, a heating portion, and a nozzle portion in one defined space. A vapor deposition apparatus deposits deposition materials on a substrate using the vapor deposition source. The vapor deposition source includes a housing, and the crucible is mounted in the housing for vaporizing the deposition materials. The heating portion is installed adjacent to the crucible in the housing for heating the crucible. The nozzle portion injects the vaporized deposition materials into a substrate disposed at an exterior of the housing through an injection nozzle. The vapor deposition source is manufactured in a smaller and lightweight form in comparison with conventional vapor deposition sources in which a crucible and a nozzle portion are arranged in different spaces.

  • Patent number: 7833579
    Abstract: A method for in-situ polycrystalline thin film growth is provided. A catalyst enhanced chemical vapor deposition (CECVD) apparatus is used to grow the polycrystalline silicon thin film. No subsequent annealing or dehydrogenating process is needed. The method comprises exhausting a chamber to form a vacuum chamber, and then purging vacuum chamber and introducing a catalyst. A substrate is then placed in the vacuum chamber and reaction gas is injected into the chamber. The reaction gas reacts with the catalyst in the chamber to grow a polycrystalline thin film on the substrate. The inventive method reduces processing time and production cost and can be used to fabricate larger devices due to the elimination of bulky annealing equipment.

  • Patent number: 7548304
    Abstract: The invention provides a chuck plate assembly that includes a shadow mask formed with a predetermined pattern; a shadow mask frame holding the shadow mask and having heat-radiating and cooling functions; a substrate aligned with the shadow mask and onto which deposition materials from a deposition source are deposited; and a chuck plate, attaching the substrate to the shadow mask, that includes a refrigerant circulating duct. The temperature of the substrate is optimized in consideration of the temperature of the shadow mask so that an alignment error due to thermal deformation is minimized. That is, the temperature of the shadow mask itself is prevented from rising, and thereby prevents deformation of the shadow mask due to thermal expansion, which improves the precision of a substrate pattern position.
