摘要: Various implementations of hybrid ceramic faceplates for substrate processing showerheads are provided. The showerhead may include an electrode embedded within the material faceplate, as well a pattern through-holes. be fully encapsulated with respect to In some implementations, heater element also faceplate. A DC voltage source electrically connected faceplate during use. easily removable from easy cleaning and replacement.
