Abstract:
A device for feeding a fluid stream saturated with organometalic compound material to a chemical vapor deposition system comprising,a vessel comprising an elongated cylindrical shaped portion having an inner surface defining a substantially constant cross section throughout the length of said cylindrical portion, a top closure portion and a bottom closure portion, said top closure portion having an inlet opening for the introduction of carrier gas and an outlet opening, said elongated cylindrical shaped portion having inlet and outlet chambers in fluid communication wherein the floor of said inlet chamber is spaced from said bottom closure portion, the floor of said inlet chamber comprising a first porous element which allows vapors generated in said inlet chamber to pass into said outlet chamber, wherein said inlet opening is in fluid communication with said inlet chamber and said outlet opening is in fluid communication with said outlet chamber, wherein said inlet opening is in fluid communication with said inlet chamber and said outlet opening is in fluid communication with said outlet chamber, a source of solid organometallic precursor compound contained within said inlet chamber of said vessel, said device further comprising a second porous element located at said outlet opening, whereby said fluid stream exits said vessel by passing through said porous element.
