In one or more embodiments, a method for depositing a carbon hard-mask material by plasma-enhanced chemical vapor deposition (PECVD) includes heating a substrate contained within a process chamber to a temperature in a range from about 100 C to about 700 C and producing a plasma with a power generator emitting an RF power of greater than 3 kW. In some examples, the temperature is in a range from about 300 C to about 700 C and the RF power is greater than 3 kW to about 7 kW. The method also includes flowing a hydrocarbon precursor into the plasma within the process chamber and forming a carbon hard-mask layer on the substrate at a rate of greater than 5,000/min, such as up to about 10,000/min or faster.

A processing chamber may include a gas distribution member, a metal ring member below the gas distribution member, and an isolating assembly coupled with the metal ring member and isolating the metal ring member from the gas distribution member. The isolating assembly may include an outer isolating member coupled with the metal ring member. The outer isolating member may at least in part define a chamber wall. The isolating assembly may further include an inner isolating member coupled with the outer isolating member. The inner isolating member may be disposed radially inward from the metal ring member about an central axis of the processing chamber. The inner isolating member may define a plurality of openings configured to provide fluid access into a radial gap between the metal ring member and the inner isolating member.

A method of forming a radio frequency (RF) strap for use in a process chamber is provided. The method includes positioning a core strap including a first material that is electrically and thermally conductive in a first electrochemical bath. The first electrochemical bath includes a first solvent and a first plating precursor. The method further includes forming a first protective coating on an outer surface of the core strap, removing the first solvent and the first plating precursor from the core strap having the first protective coating formed thereon, post-treating the core strap having the first protective coating formed thereon, positioning the core strap having the first protective coating formed thereon in a second electrochemical bath, and forming a second protective coating on an outer surface of the first protective coating. The first protective coating includes nickel, the second electrochemical bath includes a second solvent and a second plating precursor, and the second protective coating includes gold.
