    Abstract: A method includes immersing an article comprising a yttrium based oxide in an acidic cleaning solution comprising water and 1-10 mol% HF acid. A portion of the yttrium based oxide is dissolved by the HF acid. A yttrium based oxy-fluoride is formed based on a reaction between the HF acid and the dissolved portion of the yttrium based. The yttrium based oxy-fluoride is precipitated onto the article over the yttrium based oxide to form a yttrium based oxy-fluoride coating. The acidic cleaning solution may include a yttrium based salt, which may additionally react with the HF acid to form more of the yttrium based oxy-fluoride.

    Abstract: Slit valve gates and methods for cleaning are provided. Slit valves include: a slit valve gate configured to seal an opening of a process chamber, the slit valve gate comprising a surface that faces a processing volume of the process chamber; and a non-porous anodized coating on the surface of the slit valve gate. Methods of cleaning include: immersing the slit valve gate in a tank comprising deionized water; sonicating the slit valve gate at a first power density of about 6 W/cm 2 to about 15 W/cm 2 and a frequency of about 25 kHz to about 40 kHz for a first period of time; sonicating the slit valve gate at a second power density of about 30 W/cm 2 to about 45 W/cm 2 and a frequency of about 25 kHz to about 40 kHz for a second period of time; and removing the slit valve gate from the tank.
