Abstract:
1. A distributor assembly comprising: a first chamber including an interior for receiving a solid material and carrier gas; a heating element associated with the first chamber for providing a temperature high enough to vaporize at least a portion of the solid material into a vapor; a first flow path located outside and at least partially surrounding the first 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 second flow path for receiving the vapor and the carrier gas from the first flow path and for providing a material flow sufficiently indirect to maintain the substantially uniform vapor/carrier gas composition including a flow path inlet located proximate to an outlet of the first flow path and a flow path outlet offset from the flow path inlet such that the flow direction of the vapor/carrier gas must change while flowing from the flow path inlet to the flow path outlet; and an outlet for directing the uniform vapor/carrier gas composition for deposition onto a surface of a substrate.
