  • Patent number: 8025733
    Abstract: A deposition apparatus includes a vacuum chamber and a heating crucible. A substrate, on which deposition films are formed, is installed in the vacuum chamber. The heating crucible is installed opposite to the substrate so as to vaporize an organic compound. The heating crucible includes a main body and an inner plate. The main body includes a space which contains the organic compound and a nozzle through which the organic compound that is vaporized is discharged. The inner plate is installed within the main body and includes at least one opening formed around an edge of an area facing the nozzle, so as to transmit the vaporized organic compound.
