Abstract: A component capable of being exposed to a plasma in a process chamber has a structure having an electroplated coating comprising yttrium-containing species. The electroplated coating can include zirconium oxide, or can have an oxide layer thereon. In another embodiment the electroplated coating comprises a first species and is coated with a second electroplated coating comprising a second species that is different from the first species. The electroplated coating is resistant to corrosion in the plasma. In another embodiment, the electroplated coating has an interface having a thickness with a first concentration gradient of an yttrium-containing species and a second concentration gradient of a second species. An electroplated coating having a layer comprising first and second concentration gradients of first and second metals can be formed by varying the concentration of the first and second metal electrolyte species in the electroplating bath to electroplate the coating.

Abstract: Embodiments in accordance with the present invention relate to a number of techniques, which may be applied alone or in combination, to reduce charge damage of substrates exposed to electron beam radiation. In one embodiment, charge damage is reduced by establishing a robust electrical connection between the exposed substrate and ground. In another embodiment, charge damage is reduced by modifying the sequence of steps for activating and deactivating the electron beam source to reduce the accumulation of charge on the substrate. In still another embodiment, a plasma is struck in the chamber containing the e-beam treated substrate, thereby removing accumulated charge from the substrate. In a further embodiment of the present invention, the voltage of the anode of the e-beam source is reduced in magnitude to account for differences in electron conversion efficiency exhibited by different cathode materials.
