Abstract
An apparatus for depositing one or more organic material layers of an OLED lighting device upon a first region of a substrate and one or more conducting layers upon a second region, wherein the conducting layers partially or completely cover and extend beyond one side of the organic layers, comprising: a reusable mask in contact with the substrate, at least one mask open area having an overhang feature; one or more sources of vaporized organic material, selected to form layers of the OLED lighting device, and the vaporized organic material plume is shaped, on the side corresponding to the mask overhang feature, so as to limit substantial transfer of organic material on said side to angles less than or equal to a selected cutoff angle to the first region; and one or more sources of vaporized conducting material that transfer conducting material to the second region, wherein the second region partially or completely overlaps the first region and extends beyond the first region on the side corresponding to the overhang feature of the mask.
