  • Patent number: 8986783
    Abstract: A method of depositing a material on a substrate is provided for use in manufacturing electronic and display devices such as semiconductors, liquid crystal displays, and organic light emitting diode displays. A deposition material stored in a first deposition source section is heated to evaporate the deposition material. A second deposition source section, which is separate from the first deposition source section, is cooled. The first deposition source section is cooled, and deposition material stored in a second deposition source section is heated so as to alternately supply evaporated deposition material from the first and second deposition source sections to a feed section. The evaporated deposition material from the feed section is supplied to a nozzle section. A substrate can be provided to receive the evaporated deposition material from the nozzle section. A thin film of deposition material can then be formed on the substrate.
