  • Patent number: 9062368
    Abstract: A method for in-situ monitoring of gas-phase photoactive organic molecules in real time while depositing a film of the photoactive organic molecules on a substrate in a processing chamber for depositing the film includes irradiating the gas-phase photoactive organic molecules in the processing chamber with a radiation from a radiation source in-situ while depositing the film of the one or more organic materials and measuring the intensity of the resulting photoluminescence emission from the organic material. One or more processing parameters associated with the deposition process can be determined from the photoluminescence intensity data in real time providing useful feedback on the deposition process.
    Type: Grant

    Date of Patent: June 23, 2015
    Assignee: The Regents of the University of Michigan
    Inventors: Stephen R. Forrest, Garen Vartanian, Cedric Rolin
  • Patent number: 8796067
    Abstract: A method for forming an organic material layer on a substrate in an in-line deposition system is disclosed. In one aspect, the organic material is deposited with a predetermined non-constant deposition rate profile, which includes a first predetermined deposition rate range provided to deposit at least a first monolayer of the organic material layer with a first predetermined average deposition rate and a second predetermined deposition rate range provided to deposit at least a second monolayer of the organic material layer with a second predetermined average deposition rate. The injection of organic material through the openings of the injector is controlled for realizing the predetermined deposition rate profile.
