    the DC regenerative electrical energy into fixed. frequency utility electric power. Energy costs and environmental concerns are placing greater importance on variable. frequency drive systems in general. The importance of options for increased energy. efficiency and over voltage recovery is increasing
  • MICRO: Controlling particles in sputter deposition modules
    the ejection of material from a surface caused by the bombardment of energetic ions. A plasma is generated by flowing a process gas (usually argon) through a vacuum chamber and applying a negative dc bias to a target (or cathode) made from the desired deposition material. The positive ions generated
