  • Publication number: 20140080312
    Abstract: A wafer is held horizontally and rotated by a substrate holding mechanism. An aqueous alkaline solution is supplied to a wafer by a nozzle and caused to flow from a central portion to a peripheral edge portion of the wafer, thereby etching the wafer. An amount of oxygen, which is equal to or more than the amount of oxygen in atmospheric air involved in the aqueous alkaline solution flowing on the wafer, is previously dissolved in the aqueous alkaline solution.

  • Patent number: 8293364
    Abstract: A highly shrinkable fiber composed of nylon-MXD6 polymer and nylon-6 polymer, characterized in that a weight ratio therebetween is in the range of 35:65 to 70:30, and that each thereof exhibits a breaking strength of 4.00 cN/dtex or greater. Preferably, the weight ratio between nylon-MXD6 polymer and nylon-6 polymer of the highly shrinkable fiber is in the range of 45.55 to 55:45. The highly shrinkable fiber exhibits a high shrinkage ratio in boiling water, so that when the highly shrinkable fiber is used in a woven fabric, there can be realized a high density.

  • Patent number: 8038798
    Abstract: A substrate cleaning apparatus is capable of individually setting a threshold value for use in making a check of a resistivity during a rinsing process on a recipe setting screen in each process step. Thus, by setting each threshold value depending on the type of liquid chemical to be used immediately before the rinsing process, the substrate cleaning apparatus can use an optimum threshold value during the rinsing process in each process step to make a check of the resistivity. This allows the proper completion of the rinsing process in each process step.

  • Patent number: 7541293
    Abstract: According to the present invention, a process for changing the form of a processed film is performed to planarize it before the processed film which is formed on a wafer is processed in a manufacturing process of a semiconductor device. As the process for changing the form of the processed film, there may be exemplified a single wafer type wet etching process. The compatibility of the processed film with processing means is taken into consideration and, for instance, the wet etching process is applied to the processed film so as to eliminate parts incompatible with the processing means, so that a distribution in-plane of the processed film is previously improved.
