    Abstract: This invention relates to a chemical vapor deposition process for forming Zr or Hf oxynitride films suitable for use in electronic applications such as gate dielectrics. The process comprises: a. delivering a Zr or Hf containing precursor in gaseous form to a chemical vapor deposition chamber; and, b. simultaneously delivering an oxygen source and a nitrogen source to the chamber separately, such that mixing of these sources with the precursor does not take place prior to delivery to the chamber; and, c. contacting the resultant reaction mixture with a substrate in said chamber, said substrate heated to an elevated temperature to effect deposition of the Zr or Hf oxynitride film, respectively. A silicon containing precursor may be added simultaneously to the chamber for forming Zr or Hf silicon oxynitride films.

    Abstract: An opaque, low resistivity silicon carbide and a method of making the opaque, low resistivity silicon carbide. The opaque, low resistivity silicon carbide is doped with a sufficient amount of nitrogen to provide the desired properties of the silicon carbide. The opaque, low resistivity silicon carbide is a free-standing bulk material that may be machined to form furniture used for holding semi-conductor wafers during processing of the wafers. The opaque, low resistivity silicon carbide is opaque at wavelengths of light where semi-conductor wafers are processed. Such opaqueness provides for improved semi-conductor wafer manufacturing. Edge rings fashioned from the opaque, low resistivity silicon carbide can be employed in RTP chambers.
