Abstract

Official abstract text for this publication.

To manufacture a chamber component for a processing chamber, an aluminum coating is formed on an article comprising impurities, the aluminum coating being substantially free from impurities.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method of manufacturing a chamber component for a processing chamber comprising: forming an aluminum coating on an article comprising impurities, the aluminum coating being substantially free from impurities. 2 . The method of claim 1 , wherein the aluminum coating has a thickness in a range from about 0.8 mils to about 5 mils. 3 . The method of claim 1 , further comprising anodizing the aluminum coating to form an anodization layer. 4 . The method of claim 3 , wherein the anodization layer has a thickness in a range from about 30% to about 70% of the thickness of the aluminum coating. 5 . The method of claim 3 , wherein a surface roughness of the anodization layer is about 40 micro-inch. 6 . The method of claim 1 , wherein the article comprises an alloy of at least one of aluminum, copper, or magnesium. 7 . The method of claim 1 , wherein forming the aluminum coating comprises performing electroplating. 8 . A chamber component for a processing chamber, comprising: an article that comprises impurities; an aluminum coating on the article, the aluminum coating being substantially free from impurities. 9 . The chamber component of claim 8 , wherein the aluminum coating has a thickness in a range from about 0.8 mils to about 5 mils. 10 . The chamber component of claim 8 , wherein the anodization layer has a thickness in a range from about 0.4 mils to about 4 mils. 11 . The chamber component of claim 8 , wherein a surface roughness of the anodization layer is about 40 micro-inch. 12 . The chamber component of claim 8 , wherein about half of the anodization layer is formed from conversion of the aluminum coating during anodization. 13 . The chamber component of claim 8 , wherein the article comprises an alloy of at least one of aluminum, copper, or magnesium. 14 . The chamber component of claim 8 , wherein the article comprises a ceramic material. 15 . The chamber component of claim 8 , wherein aluminum coating is electroplated on the article.
