Abstract:
1. A method for vaporizing organic material and condensing it onto a surface to form a layer, comprising: (a) providing a quantity of first organic material in a powdered form in a first container and a quantity of second organic material in a second container spaced from the first container; (b) fluidizing the first organic material in the first container, mechanically transferring material consisting of the fluidized first organic material from the first container into a manifold using an auger structure, and vaporizing the first organic material in the manifold; (c) fluidizing the second organic material in the second container, mechanically transferring material consisting of the fluidized second organic material from the second container into the manifold using an auger structure and vaporizing the second organic material in the manifold where the first and second vaporized organic materials are mixed in the manifold; and (d) delivering from the manifold the mixed vaporized materials to the substrate surface to form the layer.
