Surface treated aluminum nitride baffle
Methods and apparatus relating to aluminum nitride baffles are provided herein. In some embodiments, a baffle for use in semiconductor process chambers may include a body comprising aluminum nitride and a metal oxide binding agent, wherein a ratio of aluminum nitride to metal oxide on a surface of the body is greater than or equal to the ratio within the body. In some embodiments, the body may have a center stem and an outer annulus coupled to and extending radially outwards from a lower portion of the center stem. In some embodiments, a method of fabricating a baffle may include sintering aluminum, nitrogen, and a metal oxide binding agent to form a body of the baffle, the body having excess metal oxide binding agent disposed on a surface thereof; and removing a bulk of the excess metal oxide binding agent from a surface of the body.
