Abstract: A method of removing moisture efficiently in the gas supply system by evacuation at normal temperature without using the baking method. The method involves flowing a gas to remove moisture in the gas supply system with the flow pressure of the gas to remove moisture set at not lower than a minimum pressure at which the gas flow becomes viscous and not higher than a water saturated vapor pressure at a flow temperature of the gas to remove moisture. The gas to remove moisture achieves a viscous flow when a mean free path of gas molecules is smaller than a diameter of piping of the gas supply system. If the gas for removing moisture is evacuated at normal temperature under such conditions, the adsorbed moisture on an inside surface of the piping and in the valves and filters can be removed effectively.

Abstract: A process of supplying moisture at low flow rates which permits high precision control of the flow of moisture to a semiconductor manufacturing line from an apparatus for the generation of moisture, characterized in that the flow of hydrogen to a moisture-generating reactor is controlled by means of a flow controller in such a way that an amount of hydrogen as fed is gradually increased from the start and reaches a specific set level such that when a specific time has passed, a predetermined rate of moisture begins to be produced and supplied to the semiconductor manufacturing line. The moisture is generated in the apparatus for generation of moisture in which hydrogen and oxygen are (a) fed into a reactor provided with a coat of platinum on the wall in the interior space, (b) enhanced in reactivity by the platinum catalytic action, and (c) caused to instantaneously react with each other at a temperature lower than the ignition point to produce moisture without undergoing combustion at a high temperature.

Abstract: A reactor comprising a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, having a gas-diffusing member provided in an internal space of the body, and having a platinum coating on an internal wall surface of the body. Hydrogen and oxygen fed from the inlet are diffused by the gas-diffusing member and then come into contact with the platinum coating to enhance reactivity, thereby producing water. A temperature of the reactor is held to be below an ignition temperature of hydrogen or a hydrogen-containing gas. The platinum-coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or nitride on the wall surface, and forming the platinum coating on the barrier coating.

Abstract: Process for generating moisture for use in semiconductor manufacturing, the process comprising feeding hydrogen and oxygen into a reactor provided with a platinum-coated catalyst layer on an interior wall, thus enhancing the reactivity between hydrogen and oxygen by catalytic action and instantaneously reacting the reactivity-enhanced hydrogen and oxygen at a temperature below the ignition point to produce moisture without undergoing combustion at a high temperature, wherein the amount of unreacted hydrogen occurring in the generated moisture in starting up or terminating the moisture generating reaction is minimized and wherein undesired reactions such as undesired silicon oxide film coating are avoided. When the generation of moisture is started up by feeding hydrogen and oxygen into the reactor provided with a platinum-coated catalyst layer on the inside wall thereof, oxygen first starts to be fed and, some time after that, the supply of hydrogen is begun.
