  • Publication number: 20130228001
    Abstract: A method for forming an undercut portion of a formed article formed by plastically deforming a plate-shaped workpiece and a method for manufacturing a formed article having an undercut portion are provided. In these methods, the undercut portion is formed by press working performed using a punch and a die. These methods make the forming work more economical and more efficient. An outer portion of a plate member 91 (plate-shaped workpiece) located outward of a portion where an inwardly inclined portion 94 (undercut portion) is to be formed is bent by an angle determined such that an undercut surface 94a which constitutes the inwardly inclined portion 94 becomes parallel to the pressing direction of a punch 110. In addition, a peripheral wall portion 93 inclined by an angle corresponding to the bending angle is formed on the outer portion.

  • Patent number: 8277673
    Abstract: In a plasma processing method, a conductor of an electrostatic chuck (ESC) and an electrode are electrically grounded prior to starting the plasma processing. A DC voltage with a polarity is applied to the conductor at a first time point after loading a substrate on the electrode. Then, the electrode is switched from an electrically grounded state to an electrically floating state at a second time point. A RF power is then applied to the electrode at a third time point. The application of the RF power is stopped at a fourth time point after a specified time has lapsed from the third time point. Then, the electrode is switched from the electrically floating state to the electrically grounded state at a fifth time point. Thereafter, the application of the DC voltage is stopped and the conductor is restored to a ground potential at a sixth time point.
