VESSEL AND METHOD FOR DELIVERY OF PRECURSOR MATERIALS

摘要

PROBLEM TO BE SOLVED: To provide a vessel for conveying a precursor-containing fluid stream from a precursor material contained within the vessel using a carrier gas.SOLUTION: The vessel defines an interior volume segmented into an upper volume and a lower volume, the upper volume being in fluid communication with the lower volume, the lower volume containing substantially all of the precursor material and being separated from the upper volume by a separator. The vessel includes a diffuser tube that extends from an inlet port through the separator, has a distal end having a plurality of openings formed therein and extends along the bottom interior wall of the vessel.SELECTED DRAWING: Figure 1
