摘要:
A method of manufacturing a semiconductor device includes subjecting a semiconductor wafer, which includes a copper layer formed above a semiconductor substrate and covered with an insulating film, to a dry etching using a fluorocarbon gas to partially remove the insulating film, thereby at least partially exposing a surface of the copper layer. The copper layer, the surface of which is at least partially exposed is subjected to a nitrogen plasma treatment. The semiconductor wafer having the nitrogen plasma-treated copper layer is exposed to atmosphere, and then the semiconductor wafer is subjected to a surface treatment.

A method for manufacturing an electronic device using a closed-type transport container, includes: controlling relative humidity inside the closed-type transport container to be lower than ambient relative humidity outside the closed-type transport container on a particular interprocess transport path in which an intermediate product stored in the closed-type transport container is transported from a first manufacturing process to a second manufacturing process. The first manufacturing process allows basic compounds containing nitrogen atoms to be released from the intermediate product. The second manufacturing process is susceptible to degradation due to contamination by the basic compounds.

A local clean robot-transport plant includes: a plurality of manufacturing apparatuses; a plurality of closed-type transport containers; a container discrimination/selection apparatus; an apparatus group control server. Each of the plurality of closed-type transport containers stores and transports an intermediate product of manufacturing processes along a plurality of interprocess transport paths defined among the plurality of manufacturing apparatuses in accordance with a flow of the manufacturing processes. The container discrimination/selection apparatus is configured to discriminate and select the closed-type transport container of transport type 1 and the closed-type transport container of transport type 2, respectively, from among the plurality of closed-type transport containers. The apparatus group control server is configured to collectively control operation of the plurality of manufacturing apparatuses and the container discrimination/selection apparatus to move the closed-type transport container of transport type 2 to a specific interprocess transport path and to move the closed-type transport container of transport type 1 to the interprocess transport path other than the specific interprocess transport path.

A flower pot for group planting of flower plants or the like which is mounted on a pole comprises a flower pot body (1) having planting openings (6) of which upper part is opened and provided in a plurality of locations in the periphery of said body (1), and having a hole (8) provided in the bottom of said body for inserting the pole; and a cylindrical mounting member (2) for inserting the upper part of said pole, at least the bottom of said mounting member is opened and said mounting member is fixedly or removably mounted vertically around said hole (8). The outer face of said flower pot is covered by the group planted flower plants and not exposed when said flower pot in which flower plants have been group planted is mounted on the pole, and accordingly the beauty of the flowers planted in said flower pot is kept well and the decoration effect is increased, and said flower pot is securely mounted on the pole and accordingly does not fall even when subjected to strong winds.

A blade of a gas turbine includes a main body having a dovetail portion and a blade portion extending from the dovetail portion. A cooling air passage for flowing a cooling air is formed in the main body to cool the blade portion. The passage includes a cooling air inlet port open to the dovetail portion and an outlet port open to an extended tip of the blade portion. A first passage portion extends from the inlet port to the portion close to the extended tip along a leading edge of the blade portion. A final passage portion extends from the dovetail portion to the outlet port. The flow sectional area of the final passage portion is gradually decreased from the dovetail portion toward the outlet port. The final passage portion communicates with a number of film cooling holes which are open to the suction side surface of the blade portion.
摘要:
By locally heating or cooling a substrate in an etching process, temperature unevenness is controlled, and convection currents of an etching liquid are restricted simultaneously. By setting the etching temperature low in an initial stage of the etching process and increasing it in a final stage, uniform and quick etching is possible. In a drop etching method, generation of bubbles can be prevented to ensure uniform etching by providing gas release openings in a member opposed to the substrate.

A combined cycle power plant comprises a gas turbine system and a steam cycle system having a steam turbine to be driven by the steam generated by the waste heat of the exhaust gas of the gas turbine system, wherein the steam from the steam cycle system flows through a gas turbine cooling system of the gas turbine to cool the gas turbine blades and other elements of the gas turbine system to be cooled and the waste heat of the gas turbine system is effectively collected. The gas turbine cooling system is supplied selectively with bleed air from the compressor of the gas turbine or the steam provided from another steam cycle system in order to ensure a sufficient coolant supply at the time of starting and stopping the plant and during the operation with a partial load.

A transition piece 10 in an embodiment is provided with an inner duct 20 through which a combustion gas is led to a turbine part 130 and an outer duct 30 that is provided so as to cover an outer periphery of the inner duct 20 and has a plurality of ejection holes 31 to eject air onto an outer peripheral surface of the inner duct 20 formed therein. It is structured such that a channel cross-sectional area of a cooling air channel 50 that is formed between the inner duct 20 and the outer duct 30 and through which the air ejected from the ejection holes 31 flows gradually decreases at an air flow downstream side rather than the portion where the ejection holes 31 are formed, and gradually increases from a throat portion 60 having the minimized channel cross-sectional area to an air flow downstream side.
