Abstract:
1. A substrate processing system for forming a vapor from a solid precursors by distributing heat to the precursor in a sealed container, the system comprising: a vessel configured to hold units of solid precursor, the vessel including a base, a top portion opposite the base, and a sidewall extending from the top portion toward the base, the vessel having no heater therein; an inlet that introduces a carrier gas into the vessel; an outlet that releases gas comprising the vapor from the solid precursor from the vessel; and a plurality of thermally conductive protrusions extending from at least one of the vessel base and the vessel sidewall, the thermally conductive protrusions positioned and dimensioned to extend through the units of solid precursor and to conduct heat generated by a heater external to the vessel from at least one of the vessel base and the vessel sidewall to the units of solid precursor when the vessel is loaded with the units of solid precursor, wherein the thermally conductive protrusions each have a top surface that is space apart from the vessel top portion, and wherein the thermally conductive protrusions do not form part of an electrical or fluid circuit.
