    摘要: Process deposits formed on a component of a process chamber are cleaned. In the cleaning method, gas holes in the component are mechanically pinned to clean the process deposits therein. A ceramic portion of the component is then exposed to an acidic solution, such as a solution of hydrofluoric acid and nitric acid. Mechanical pinning of the gas holes may be repeated after the acid cleaning step. The component is then plasma stabilized in a plasma zone by introducing a non-reactive gas into the plasma zone and forming a plasma of the non-reactive gas in the plasma zone. In one version, the component comprises an electrostatic chuck comprising a ceramic covering an electrode and having the gas holes therein.

    摘要: Embodiments of the present invention provide structures for reducing erosion of a slit valve utilized in the fabrication of semiconductor devices. Specifically, non-metallic slit valve components such as a compressible sealing member and a barrier that assist in sealing the valve closure against the slit valve seat, are positioned on the valve seat rather than on the valve closure. This orientation removes the seal and the seal barrier from the direct line of sight of the plasma within the processing chamber, reducing exposure of the sealing member and seal barrier slit valve components to erosion and thereby extending the lifetime of the valve.
