Patent ID: 7846256

Claim:
A replaceable film precursor support assembly for supporting a film precursor and configured to be stacked with one or more other film precursor support assemblies in a film precursor evaporation system in a container thereof having an outer wall, a bottom, and a lid sealably coupled to said container and having an outlet in said lid sealably coupled to a thin film deposition system, the assembly comprising: a replaceable tray having a bottom, an inner wall extending upwardly from said bottom and terminating in an inner edge and an outer wall extending upwardly from said bottom and terminating in an outer edge, said inner and outer walls being configured to retain a film precursor therebetween, one of said walls being a stackable wall to support another of said replaceable trays and the other of said walls being shorter than said stackable wall, said stackable wall having one or more tray openings formed therein and configured to flow a carrier gas from a carrier gas supply system, then over said film precursor radially towards said other wall of said replaceable tray as precursor evaporates into said carrier gas, and then through said outlet in said lid with film precursor vapor; and one or more precursor stabilization elements positioned within said replaceable tray and configured to substantially preserve the surface area of film precursor for evaporation into said carrier gas.
