Methods and apparatus for processing a substrate are provided herein. In some embodiments, an apparatus for substrate processing includes a process chamber having a chamber body defining an inner volume; and a silicon containing coating disposed on an interior surface of the chamber body, wherein an outer surface of the silicon containing coating is at least 35 percent silicon (Si) by atom. In some embodiments, a method for forming a silicon containing coating in a process chamber includes providing a first process gas comprising a silicon containing gas to an inner volume of the process chamber; and forming a silicon containing coating on an interior surface of the process chamber, wherein an outer surface of the silicon containing coating is at least 35 percent silicon.

Embodiments of the present invention provide an apparatus for constraining and supporting the lift pins to prevent or minimize lateral movement of the lift pins that causes substrate hand-off problems and associated degradation in substrate processing characteristics and results. In one embodiment, a lift pin assembly for manipulating a substrate above a support surface of a substrate support comprises a plurality of lift pins movable between an up position and a down position. The lift pins include top ends and bottom ends. The top ends are configured to be lifted above the support surface of the substrate support to contact a bottom surface of the substrate in the up position. The top ends are configured to be positioned at or below the support surface of the substrate support in the down position. A lift pin connecting member is attached to the plurality of lift pins at attachment locations at or near the bottom ends of the lift pins to maintain fixed relative distances between the lift pins at the attachment locations and to move with the lift pins between the up position and the down position.

A method and apparatus for removing deposition products from internal surfaces of a processing chamber, and for preventing or slowing growth of such deposition products. A halogen containing gas is provided to the chamber to etch away deposition products. A halogen scavenging gas is provided to the chamber to remove any residual halogen. The halogen scavenging gas is generally activated by exposure to electromagnetic energy, either inside the processing chamber by thermal energy, or in a remote chamber by electric field, UV, or microwave. A deposition precursor may be added to the halogen scavenging gas to form a deposition resistant film on the internal surfaces of the chamber. Additionally, or alternately, a deposition resistant film may be formed by sputtering a deposition resistant metal onto internal components of the processing chamber in a PVD process.
