Abstract: Embodiments of the present disclosure generally relate to a substrate processing chamber, and methods for cleaning the substrate processing chamber are provided herein. An electrode cleaning ring is disposed in a lower portion of a process volume (e.g., disposed below a substrate support in the process volume). The electrode cleaning ring is a capacitively coupled plasma source. The electrode cleaning ring propagates plasma into the lower portion of the process volume. RF power is provided to the electrode cleaning ring via an RF power feed-through. The RF plasma propagated by the electrode cleaning ring removes deposition residue in the lower portion of the process volume.

The as-deposited boron-containing material may be characterized by a surface roughness of less than or about 2 nm, and a stress level of less-than or about ?500 MPa. In some embodiments, a layer of the boron-containing material may function as a hardmask.

Abstract: A system for modifying the uniformity pattern of a thin film deposited in a plasma processing chamber includes a single radio-frequency (RF) power source that is coupled to multiple points on the discharge electrode of the plasma processing chamber. Positioning of the multiple coupling points, a power distribution between the multiple coupling points, or a combination of both are selected to at least partially compensate for a consistent non-uniformity pattern of thin films produced by the chamber. The power distribution between the multiple coupling points may be produced by an appropriate RF phase difference between the RF power applied at each of the multiple coupling points.

Abstract: Implementations described herein generally relate to an apparatus for forming flowable films. In one implementation, the apparatus is a processing chamber including a first RPS coupled to a lid of the processing chamber and a second RPS coupled to a side wall of the processing chamber. The first RPS is utilized for delivering deposition radicals into a processing region in the processing chamber and the second RPS is utilized for delivering cleaning radicals into the processing region. The processing chamber further includes a radical delivery ring disposed between a showerhead and a substrate support for delivering cleaning radicals from the second RPS into the processing region. Having separate RPSs for deposition and clean along with introducing radicals from the RPSs into the processing region using separate delivery channels minimizes cross contamination and cyclic change on the RPSs, leading to improved deposition rate drifting and particle performance.
