A system for the deposition of vaporized materials on a substrate is described, comprising at least first and second orientation-independent apparatuses for directing vaporized organic materials onto a substrate surface to form first and second films, each of the first and second orientation-independent apparatuses being arranged in a different relative orientation and comprising: a chamber containing a quantity of material; a permeable member at one end of the chamber with a heating element for vaporizing the material; and a piston at the other end of the chamber for continuously feeding the material toward the permeable member as it is vaporized, whereby organic material vaporizes at a desired rate-dependent vaporization temperature at the one end of the chamber. A plurality of thin films may be deposited on a substrate using deposition apparatus in a variety of orientations. Such a design provides reduced costs and improved deposition rate control.
