    摘要: 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.

    摘要: 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.
