  • Patent number: 9343664
    Abstract: A method and apparatus for forming a magnetic layer having a pattern of magnetic properties on a substrate is described. The method includes using a metal nitride hardmask layer to pattern the magnetic layer by plasma exposure. The metal nitride layer is patterned using a nanoimprint patterning process with a silicon oxide pattern negative material. The pattern is developed in the metal nitride using a halogen and oxygen containing remote plasma, and is removed after plasma exposure using a caustic wet strip process. All processing is done at low temperatures to avoid thermal damage to magnetic materials.

  • Publication number: 20130087452
    Abstract: Embodiments of the invention generally relate to a process kit for a semiconductor processing chamber, and a semiconductor processing chamber having a kit. More specifically, embodiments described herein relate to a process kit including a cover ring, a shield, and an isolator for use in a physical deposition chamber. The components of the process kit work alone and in combination to significantly reduce particle generation and stray plasmas. In comparison with existing multiple part shields, which provide an extended RF return path contributing to RF harmonics causing stray plasma outside the process cavity, the components of the process kit reduce the RF return path thus providing improved plasma containment in the interior processing region.

  • Patent number: 7422664
    Abstract: A method for igniting a plasma in a semiconductor process chamber is provided herein. In one embodiment, a method for igniting a plasma in a semiconductor substrate process chamber having an electrically isolated anode, wherein the plasma has failed to ignite upon applying a plasma ignition voltage to a cathode of the process chamber, includes the steps of reducing the magnitude of the voltage applied to the cathode; reapplying the plasma ignition voltage to the cathode; and monitoring the process chamber to determine if the plasma has ignited. The step of monitoring the process chamber may have a duration of a first period of time. The step of reducing the magnitude of the voltage applied to the cathode may have a duration of a second period of time. The steps of reducing the cathode voltage magnitude and reapplying the plasma ignition voltage may be repeated until a plasma ignites.
