Abstract:
A system and method of cleaning a plasma processing chamber component includes removing the component from the plasma processing chamber, the removed component including a material deposited on the surface of the component. A heated oxidizing solution is applied to the material deposited on the component to oxidize a first portion deposited material. A stripping solution is applied to the component to remove the oxidized first portion of the deposited material. An etching solution is applied to remove a second portion of the deposited material and the cleaned component can be rinsed and dried.

Abstract:
A cleaning fixture assembly for protecting an electrostatic chuck suitable for supporting semiconductor substrates during a cleaning process contains a plate configured to align with and engage a backside of the electrostatic chuck, the plate having an annular seal portion surrounding a pocket. The cleaning fixture assembly also contains a first O-ring engaging the annular seal portion of the plate, a plurality of through-holes in the pocket of the plate, and a plurality of O-rings surrounding the plurality of through-holes in the pocket of the plate. The plurality of through-holes are configured to be aligned with and in fluid communication with lift pin holes and helium holes in the backside of the electrostatic chuck, and the plurality of O-rings are positioned to allow cleaning media to engage the lift pin holes and helium holes in the electrostatic chuck during a cleaning process while sealing the cleaning media from reaching the backside of the electrostatic chuck.
