Zusammenfassung:	Apparatus and methods for reducing undesirable residue material deposition and buildup on one or more surfaces within a processing chamber are provided herein. In embodiments disclosed herein, a processing chamber includes a chamber body having a chamber base, one or more sidewalls, and a chamber lid defining a processing volume; a showerhead disposed in the chamber lid and having a bottom surface adjacent the processing volume; and an isolator disposed between the chamber lid and the one or more sidewalls. The isolator includes a first end contacting the showerhead; a second end opposite the first end; an angled inner wall connected to the first end and extending radially outwardly from the first end towards the second end; and a lower inner wall at a different angle from the angled inner wall. The first end and the angled inner wall of the isolator form a first angle less than 90°.
