ABSTRACT:
Vaporizable material is supported within a vessel to promote contact of an introduced gas with the vaporizable material, and produce a product gas including vaporized material. A heating element supplies heat to a wall of the vessel to heat vaporizable material disposed therein. The vessel may include an amoule having a removable top. Multiple containers defining multiple material support surfaces may be stacked disposed within a vessel in thermal communication with the vessel. A tube may be disposed within the vessel and coupled to a gas inlet. Filters, flow meters, and level sensors may be further provided. Product gas resuting from contact of introduced gas with vaporized material may be delivered to atomic layer deposition (ALD) or similar process equipment.
