Abstract
A method for vaporizing organic material and condensing it onto a surface to form a layer, comprising: 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; fluidizing the first organic material in the first container, transferring the fluidized first organic material from the first container into a manifold, and vaporizing the first organic material in the manifold; fluidizing the second organic material in the second container, transferring the fluidized second organic material from the second container into the manifold, and vaporizing the second organic material in the manifold where the first and second vaporized organic materials are mixed; and delivering from the manifold the mixed vaporized materials to the substrate surface to form the layer.
