  • Patent number: 10934620
    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.

  • Publication number: 20140329027
    Abstract: Methods of forming gapfill silicon-containing layers are described. The methods may include providing or forming a silicon-and-hydrogen-containing layer on a patterned substrate. The methods include non-thermally treating the silicon-and-hydrogen-containing layer at low substrate temperature to increase the concentration of Si—Si bonds while the silicon-and-hydrogen-containing layer remains soft. The flaccid layer is able to adjust to the departure of hydrogen from the film and retain a high density without developing a stress. Film qualify is further improved by then inserting O between Si—Si bonds to expand the film in the trenches thereby converting the silicon-and-hydrogen-containing layer to a silicon-and-oxygen-containing layer.

  • Patent number: 8563445
    Abstract: Methods, materials, and systems are described for forming conformal dielectric layers containing silicon and nitrogen (e.g., a silicon-nitrogen-hydrogen (Si—N—H) film) from a carbon-free silicon-and-nitrogen precursor and radical-nitrogen precursor. The carbon-free silicon-and-nitrogen precursor is predominantly excited by contact with the radical-nitrogen precursor. Because the silicon-and-nitrogen film is formed without carbon, the conversion of the film into hardened silicon oxide is done with less pore formation and less volume shrinkage. The deposited silicon-and-nitrogen-containing film may be wholly or partially converted to silicon oxide which allows the optical properties of the conformal dielectric layer to be selectable. The deposition of a thin silicon-and-nitrogen-containing film may be performed at low temperature to form a liner layer in a substrate trench.

  • Patent number: 8318584
    Abstract: The formation of a gap-filling silicon oxide layer with reduced volume fraction of voids is described. The deposition involves the formation of an oxygen-rich less-flowable liner layer before an oxygen-poor more-flowable gapfill layer. However, the liner layer is deposited within the same chamber as the gapfill layer. The liner layer and the gapfill layer may both be formed by combining a radical component with an unexcited silicon-containing precursor (i.e. not directly excited by application of plasma power). The liner layer has more oxygen content than the gapfill layer and deposits more conformally. The deposition rate of the gapfill layer may be increased by the presence of the liner layer. The gapfill layer may contain silicon, oxygen and nitrogen and be converted at elevated temperature to contain more oxygen and less nitrogen. The presence of the gapfill liner provides a source of oxygen underneath the gapfill layer to augment the gas phase oxygen introduced during the conversion.
