USE OF SINTERED NANOGRAINED YTTRIUM-BASED CERAMICS AS ETCH CHAMBER COMPONENTS |
摘要 |
In accordance with this disclosure, there are provided several inventions, including an apparatus and method for creating a plasma resistant part, which may be formed of a sintered nanocrystalline ceramic material comprising yttrium, oxide, and fluoride. Example parts thus made may include windows, edge rings, or injectors. In one configuration, the parts may be yttria co-sintered with alumina, which may be transparent. |

1. A plasma resistant part adapted for use in a plasma processing chamber which is configured to produce a plasma while in an operating mode, wherein the part comprises a plasma-facing surface configured to face the plasma when the plasma chamber is in the operating mode, wherein the surface is formed of a sintered nanocrystalline ceramic material comprising yttrium in addition to oxide and/or fluoride. |
