Abstract

See full text

A method and apparatus for fabricating an organic electroluminescent device, are discussed. According to an embodiment, the method includes depositing an organic material on a substrate coupled to a first tray in a first substrate treatment unit using the first tray as a mask, depositing a metal material on the substrate coupled to a second tray in a second substrate treatment unit using the second tray as mask, wherein the deposition of the organic material or the metal material in the first and second substrate treatment units includes primarily moving the first and second trays such that the first and second trays are aligned with the substrate, when each of the first and second trays is coupled to the substrate, and secondarily moving the first and second trays and the substrate such that the substrate and the trays are aligned at predetermined positions.
