Ultra-low defect part process

Abstract:

A method for removing and preventing defects on surfaces of a component of a substrate processing chamber includes loading the component into a vacuum chamber and, with the component loaded within the vacuum chamber, baking the component at a baking temperature during a first predetermined period to remove water and defects from the surfaces of the component, and purging the component within the vacuum chamber during at least one second predetermined period to remove the defects from the vacuum chamber.
