DIRECT LIQUID INJECTOR DEVICE

A device for mixing, vaporizing and communicating a precursor element in a highly conductive fashion to a remote processing environment. A supply meter admits a precursor liquid according to a piezo controlled valve, which communicates therewith for controlling flow into a mixing manifold. A vaporizer manifold in cooperation with a carrier gas supply provides a carrier gas for contemporaneous delivery into the mixing manifold. A vaporizing component having at least a heating element in communication with the mixing manifold, in cooperation with a mixing (frit) material provided in the vaporizer body, causes a phase change of the liquid precursor into a vapor output. Delivery of the vapor outlet occurs along at least one high conductance run/vent valve located downstream from the vaporizing body, typically built into the vaporizer manifold architecture, and provides for metering of the vapor into a remote process chamber. ® KIPO & WIPO 2009
