Patent number: 8021514Abstract: A plasma processing chamber particularly useful for pre-treating low-k dielectric films and refractory metal films subject to oxidation prior to deposition of other layers. A remote plasma source (RPS) excites a processing gas into a plasma and delivers it through a supply tube to a manifold in back of a showerhead faceplate. The chamber is configured for oxidizing and reducing plasmas in the same or different processes when oxygen and hydrogen are selectively supplied to the RPS. The supply tube and showerhead may be formed of dielectric oxides which may be passivated by a water vapor plasma from the remote plasma source. In one novel process, a protective hydroxide coating is formed on refractory metals by alternating neutral plasmas of hydrogen and oxygen.Type: GrantFiled: July 11, 2007Date of Patent: September 20, 2011Assignee: Applied Materials, Inc.Inventors: Xinyu Fu, Jick M.

Patent number: 8017198Abstract: A method and apparatus for forming thin film materials via a plasma deposition process in the presence of a magnetic field. A precursor is delivered to a deposition chamber and activated to form a plasma. The plasma may be initiated in the presence of a magnetic field or subjected to a magnetic field after initiation. The plasma includes ionized and neutral species derived from the precursor and the magnetic field manipulates the plasma to effect a reduction in the population of ionized species and an enhancement of the population of neutral species. A thin film material is subsequently formed from the resulting neutral-enriched deposition medium. The method permits formation of thin film materials having a low density of defects. In one embodiment, the thin film material is a photovoltaic material and the suppression of defects leads to an enhancement in photovoltaic efficiency.Type: GrantFiled: April 24, 2009Date of Patent: September 13, 2011Assignee: Ovshinsky Innovation LLCInventor: Stanford R.
