Patent ID: 7484315

Claim:
A replaceable film precursor support assembly for use in a film precursor evaporation system comprising a container having an outer container wall and a bottom, and a lid configured to be sealably coupled to said container, said lid comprising an outlet configured to be sealably coupled to a process chamber configured to deposit a thin film on a substrate, the assembly comprising: a replaceable tray supporting a film precursor, and configured to be stacked with one or more additional stackable trays in said film precursor evaporation system, wherein said replaceable tray comprises a bottom support surface defined between an outer edge and an inner edge, a stackable outer wall extending upwardly from said outer edge and terminating in an upper support edge for supporting said one or more additional stackable trays, and an inner wall shorter than said stackable outer wall and extending upwardly from said inner edge of said bottom support surface, said film precursor between said stackable outer wall and said inner wall on said bottom support surface, wherein said inner wall defines a central flow channel in said container and said stackable outer wall, said bottom support surface, and said inner wall define a tray space, and said replaceable tray includes one or more tray openings in said stackable outer wall configured to flow a carrier gas from a carrier gas supply system, through said one or more tray openings and from said stackable outer wall over said film precursor and over said inner wall towards said central flow channel and upward through said central flow channel to exhaust through said outlet in said lid with film precursor vapor.
