Abstract
It is an object of the present invention to provide an effective way of replenishing particulate material for vaporization. This object is achieved by a method for delivering material into a deposition chamber having a vaporization zone to vaporize such material to form a layer. The improvement includes providing a cartridge defining a cavity for receiving material under a controlled environment for preventing material contamination, receiving material from the cavity and translating such received material along a feed path to the vaporization zone and removably securing the cartridge to the deposition chamber.
