FILM PRECURSOR EVAPORATION SYSTEM AND METHOD OF USING

摘要

A high conductance, multi-tray film precursor evaporation system (1 ) coupled with a high conductance vapor delivery system (40) is described for increasing deposition rate by increasing exposed surface area of film precursor. The multi-tray film precursor evaporation system (50) includes one or more trays (340). Each tray is configured to support and retain film precursor (350) in, for example, solid powder form or solid tablet form. Additionally, each tray is configured to provide for a high conductance flow of carrier gas over the film precursor while the film precursor is heated. For example, the carrier gas flows inward over the film precursor, and vertically upward through a flow channel (318) within the stackable trays and through an outlet (322) in the solid precursor evaporation system.
