Abstract:
1. A distributor assembly comprising: a first chamber for receiving a solid material and carrier gas and comprising one or more first chamber walls which are permeable to a vapor and the carrier gas but impermeable to the solid material; a heating element associated with the first chamber for vaporizing at least a portion of the solid material; a second chamber for receiving the vapor and the carrier gas from the first chamber and for providing a material flow sufficiently indirect to mix the vapor and the carrier gas into a substantially uniform vapor/carrier gas composition; a third chamber for receiving the vapor and the carrier gas from the second chamber including a third chamber inlet located proximate to an outlet of the second chamber; and a third chamber outlet for providing the uniform vapor/carrier gas composition for deposition on a surface of a substrate, wherein the third chamber outlet is offset from the third chamber inlet such that the flow direction of the vapor/carrier gas must change while flowing from the third chamber inlet to the third chamber outlet.
