Abstract:
A hydrogen mixed gas supplying apparatus, consists of: a lead flow pipe, an atomizer, a liquid storage tank and a plasma heater; wherein, the lower end of lead flow pipe is linked to the liquid storage tank through a tube such that the methanol mixed liquid stored in the liquid storage tank is lead into the lead flow pipe; at the bottom end of lead flow pipe is the atomizer that atomizes the methanol mixed liquid into mixed liquid micro particles having average diameter not over 2 μm; lead air from one end of the lead flow pipe pushes the mixed liquid micro particles to plasma heater that dissolved the mixed liquid micro particles into hydrogen ions, hydroxide ions and the corresponding free radicals;and finally, the mixed gas of low temperature hydrogen gas, carbon monoxide, methane, carbon dioxide and nitrogen gas is then generated.
Abstract:
An electrolyzer which decomposes distilled water into a new fuel composed of hydrogen, oxygen and their molecular and magnecular bonds, called HHO. The electrolyzer can be used to provide the new combustible gas as an additive to combustion engine fuels or in flame or other generating equipment such as torches and welders. The new combustible gas is comprised of clusters of hydrogen and oxygen atoms structured according to a general formula HmOn wherein m and n have null or positive integer values with the exception that m and n can not be 0 at the same time, and wherein said combustible gas has a varying energy content depending on its use.

Abstract:
A process and apparatus is disclosed for generating a mixture of phosphine and diluent gas(es). A hydrolyzable metal phosphide, preferably magnesium phosphide, is released directly into liquid water under an atmosphere of gas inert to phosphine and in a free-flowing particulate form, composed of loose metal phosphide particles. The generated mixture of phosphine and inert carrier gas, e.g. CO.sub.2, is used as such or is diluted into a gas mixing chamber with air to a concentration below the ignitability limit before being used in fumigation. Using argon as a carrier gas the phosphine mixture is suitable for semiconductor doping.
Abstract:
Described herein is an apparatus and method for delivering fluid components for semiconductor processes such as chemical vapor deposition (CVD) and chemical etch processes. Any prescribed mixture of separate fluid reagents can be delivered with extreme accuracy and precision using the apparatus we describe here. The unique embodiment of a precision fluid pumping system utilizing internal pressure and temperature transducers, capacity volume and restrictive elements that comprise a continuous pulse-free system for use in CVD applications. This system has superior performance characteristics in the areas of: accuracy, precision, repeatability of the fluid mixture delivery and continuous repeatable delivery without intermittent pulsation. We describe a novel fluid pump whose design is integrated using a closed loop feedback system composed of temperature and pressure sensors. This allows the entire system to perform to in either an isobaric-isothermal mode or an isocratic-isothermal mode. The construction of this system is separated into three principle areas (Fluid Pump Hardware), (Fluid phase change hardware) and (Control algorithms), the complete embodiment constitutes a novel invention in the field of chemical delivery as pertaining to the fabrication of semiconductor devices.
