Abstract: The present invention is an apparatus for deliverying high purity gallium trichloride in the vapor phase to a gallium nitride reactor, comprising; a source of carrier gas at an elevated pressure; a purifier to remove moisture from the carrier gas; a heater capable of heating the carrier gas to at least 80° C.; a container having a supply of gallium trichloride, a valve controlled inlet for the carrier gas having a dip tube with an outlet below the level of the gallium trichloride, a valve controlled outlet for removing the carrier gas and entrained gallium trichloride; a heater capable of heating sufficient to melt the gallium trichloride; a delivery line connected to the valve controlled outlet for carrying the entrained gallium trichloride to a reaction zone for gallium nitride. A process is also described for the apparatus.

Abstract: The present invention is an apparatus and process for storing and delivering a low vapor pressure process chemical to a process tool for semiconductor fabrication, comprising: a) a bulk container for storing the process chemical; b) a process container for delivering the process chemical to the process tool; c) a first manifold for delivering process chemical from the bulk container to the process container; d) a solvent container containing a quantity of solvent, e) a second manifold for delivering the process chemical from the process container to a process tool; f) a solvent recovery container for containing used solvent and removed process chemical, and, g) a solvent evaporator to differentially remove solvent from process chemical in the solvent recovery container by entrainment in a carrier gas, vacuum removal, heating or combinations thereof. The containers can be baffled on their inert gas inlets. The cabinet can be heated.

Abstract: A container having two ports; first block valve having two diaphragm valves, each valve having a valve seat side and a diaphragm side, each valve seat side faces the other valve seat side, and connected to the first end of a dispense conduit, one diaphragm side connected to a first port, and another diaphragm side connected to vent and or vacuum; a second valve connected to a push gas conduit and a second port.

Abstract: Vessel and method for the production and delivery of a precursor-containing fluid stream comprising the gaseous phase of a precursor material are disclosed herein. In one aspect, there is provided an vessel comprising: an interior volume wherein the interior volume is segmented into an upper volume and a lower volume wherein the upper volume and the lower volume are in fluid communication; a lid comprising a fluid inlet, a fluid outlet, an optional fill port, and an internal recess wherein at least a portion of the upper volume resides within the internal recess; a sidewall interposed between the lid and a base; and at least one protrusion that extends into the lower volume wherein the precursor is in contact with the at least one protrusion and wherein at least one protrusion extends from at least one selected from the lid, the sidewall, the base, and combinations thereof.

Abstract: A belt lock for a safety belt has a frame (10), a latching element (14) for the latching of the belt tongue (18) and a securing element (16), which secures the latching element (14) in the latched state. Furthermore, a detector device (24, 26, 28) is provided at the belt lock which detects the position of the securing element (16).
