Abstract:
Apparatus for generating a high temperature mixture of gases, the stream being supplied to a furnace for the production of oxide films on semiconductor wafers, said apparatus comprising:a) an open quartz vessel;b) a quartz cover having input and output ports and dimensioned to close the vessel;c) an input tube extending from the input port to a level proximate to the bottom of the vessel;d) means for delivering a mixture of gas and liquid to the input tube;e) an output tube extending from the output port to a region proximate to the cover;f) a multiplicity of inert chips contained in the vessel and surrounding the input tube;g) a body of high thermal conductivity material having a central opening for receiving and contacting the vessel; andh) means for heating the body and elevating the temperature of the vessel and inert chips therein, the mixture of gas and liquid being vaporized and exiting the vessel through the output tube.
