Abstract:
1. A method for depositing a material on a substrate, comprising: introducing the material as a powder and a carrier gas into a first chamber, the first chamber comprising one or more first chamber walls which are permeable to a vapor and the carrier gas but impermeable to the solid material; heating a heating element associated with the first chamber to a temperature sufficient to vaporize at least a portion of the powder into a vapor; directing the vapor through the one or more permeable first chamber walls into a second chamber positioned outside the first chamber that provides a material flow sufficiently indirect to mix the vapor and the carrier gas into a substantially uniform vapor/carrier gas composition; directing the vapor carrier gas composition from the second chamber into a first passageway formed in a block, the first passageway having an inlet and an outlet; after the vapor carrier gas composition passes through the first passageway outlet, directing the vapor/carrier gas composition from the first passageway outlet towards a portion of an external surface of the second chamber to disperse the vapor/carrier gas composition and further increase its uniformity; and directing the substantially uniform vapor/carrier gas composition towards a surface of a substrate.
