Method and apparatus for showerhead cleaning
View Patent ↗Embodiments of the present invention generally relate to a method and apparatus for ex-situ cleaning of a chamber component part. In one embodiment, a system for cleaning component parts in a cleaning chemistry is provided. The system comprises a wet bench set-up comprising a cleaning vessel assembly for holding one or more component parts to be cleaned during a cleaning process and a detachable cleaning cart detachably coupled with the cleaning vessel assembly for supplying one or more cleaning chemistries to the cleaning vessel assembly during the cleaning process.
1. A method for cleaning component parts in a cleaning chemistry comprising:
providing a cleaning vessel assembly for holding one or more component parts to be cleaned during a cleaning process, comprising:
an outer cleaning basin;
a first cleaning basin circumscribed by the outer cleaning basin;
a second cleaning basin circumscribed by the outer cleaning basin; and
a transducer positioned within the outer cleaning basin below the first cleaning basin and the second cleaning basin;
providing a detachable cleaning cart detachably coupled with the cleaning vessel for supplying one or more cleaning chemistries to the cleaning vessel assembly during the cleaning process, comprising:
an inert gas module for supplying an inert gas which may be used as a purge gas during the cleaning process;
a deionized (DI) water supply module;
a first cleaning fluid supply tank for the first cleaning basin; and
a second cleaning fluid supply tank for the second cleaning basin;
positioning a first component part in the first cleaning basin;
positioning a second component part in the second cleaning basin;
flowing a first cleaning fluid from the first cleaning fluid supply tank into the first cleaning basin;
flowing a second cleaning fluid from the second cleaning fluid supply tank into the second cleaning basin;
cycling the transducer on and off to agitate the first cleaning fluid and the second cleaning fluid; and
flowing DI water from the DI water supply module into the first cleaning basin and the second cleaning basin to purge the first cleaning fluid from the first cleaning basin and the second cleaning fluid from the second cleaning basin.
2. The method of claim 1 , wherein flowing a first cleaning fluid from the first cleaning fluid supply tank into the first cleaning basin and flowing a second cleaning fluid from the second cleaning fluid supply tank into the second cleaning basin occur simultaneously.
3. The method of claim 1 , wherein flowing a first cleaning fluid from the first cleaning fluid supply tank into the first cleaning basin and flowing a second cleaning fluid from the second cleaning fluid supply tank into the second cleaning basin occur sequentially.
4. The method of claim 1 , wherein the first cleaning fluid and the second cleaning fluid are different chemistries.
5. The method of claim 1 , further comprising:
detaching the cleaning cart from the cleaning vessel;
moving the cleaning cart to a second cleaning vessel assembly; and attaching the cleaning cart to the second cleaning vessel assembly.
