Patent JP-H10340909-A (JP)
Title: Manufacture of semiconductor integrated circuit device
Inventor: TANABE YOSHIKAZU
IPC: H01L27/108
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a technique for safely removing hydrogen in an exhaust gas from a vapor-phase treatment device, in a vapor-phase treatment process of a semiconductor wafer using hydrogen. SOLUTION: After a gate electrode of a polymetallic structure is formed on a semiconductor wafer 1A having a gate oxide film formed thereon, hydrogen gas containing water at a low concentration generated from hydrogen and oxygen by a catalytic action is supplied to the semiconductor wafer 1A to selectively oxidize its main surface, thereby improving the profile of a sidewall end portion of the gate electrode. After that, hydrogen in an exhaust gas from an oxidation furnace is caused to react with oxygen by a catalytic method, thus completely converting hydrogen into water.
Patent JP-S629197-A (JP)
Title: Finned heat exchanger
Inventor: OBATA MAKOTO
IPC: F28F1/32
Filed: 1985-07-05
Abstract: PURPOSE:To restrain spaces between fins from being blockaded by frost upon frosting by a method wherein slit or louver type cut-and-raised parts are arranged on the surface of the fins at gaps in the step direction of heat transfer tubes and the widths of these cut-and-raised parts are shortened stepwise from the inflow side of air to the outflow side of the same. CONSTITUTION:The width P1 of the slit type cut-and-raised part 4 is long at the air inflow part of the fin 1, therefore, the thickness of temperature boundary layer of the cut-and-raised part 4 is thick and the heat transfer rate of local air side becomes low; as a result, the thickness of frost 3 at the air inflow part of the fin 1 becomes thin. The thickness of temperature boundary layer of cooled and dehumidified air becomes thin gradually, and the heat transfer rate of local air side of the same air becomes higher gradually since the widths P2-P5 of the cut-and-raised parts 5-8 are shortened stepwise with respect to the outflow direction of the air; therefore, heat exchange between the cooled and dehumidified air is effected gradually and the frost 3 is formed. Even in case the frost 3 on the surface of the fin 1 forms the layer of frost of uniform thickness, the space between fins 1 will never be blockaded. Accordingly, the time of room heating operation may be extended, the number of times of defrosting operation may be decreased, and comfortable property upon room heating may be improved.
