Abstract:
The invention includes a method of coating a substrate with a plasma etch-resistant layer that exhibits reduced particulation comprising applying an coating layer to a substrate wherein coating layer has a thickness of about 20 microns or less and wherein the coating layer, after exposure to a fluorine based plasma for an amount of time, is substantially free of any cracks or fissures that span the cross section of the coating layer.A coated substrate prepared by the methods described. Also included in the invention are coated substrates for use as a structural element in a fluorine-based semiconductor wafer processing protocol, wherein the coating is a coating layer having a thickness of about 20 microns or less and wherein the coating layer, after exposure to a fluorine based plasma for an amount of time, is substantially free of any cracks or fissures that span the cross section of the coating layer and exhibits reduced particulation.Included are structural elements used in a fluorine-based semiconductor wafer processing protocol, wherein at least a portion of a surface of a structural element is coated with a coating layer that having a thickness of about 20 microns or less and wherein the coating layer, after exposure to a fluorine based plasma for an amount of time, is substantially free of any cracks or fissures that span the cross section of the coating layer and exhibits reduced particulation.
