Abstract:
1. A method for vaporizing organic materials onto a surface, to form a film comprising: (a) providing a quantity of organic material in a fluidized powdered form; (b) metering the powdered organic material and directing a stream of such fluidized powder onto a first member; (c) heating the first member so that as the metered stream of fluidized powder contacts the first member such fluidized powder is vaporized; (d) collecting the vaporized organic material in a manifold; (e) providing a second member formed with at least one aperture in communication with the manifold that permits the vaporized organic material to be directed onto the surface to form a film; and (f) providing a deposition chamber and interrupting the vaporization and thereby reducing contamination of the deposition chamber walls and conserving the organic materials when a substrate is not being coated.
