Patent number: 10934620Abstract: 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.Type: GrantFiled: November 27, 2017Date of Patent: March 2, 2021Assignee: Applied Materials, Inc.Inventors: Ying Ma, Daemian Raj, Jay D.

Publication number: 20140329027Abstract: 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.Type: ApplicationFiled: July 31, 2013Publication date: November 6, 2014Applicant: Applied Materials, Inc.Inventors: Jingmei Liang, Nitin K.

Patent number: 8563445Abstract: 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.Type: GrantFiled: February 10, 2011Date of Patent: October 22, 2013Assignee: Applied Materials, Inc.Inventors: Jingmei Liang, Xiaolin Chen, DongQing Li, Nitin K.

Patent number: 8318584Abstract: 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.Type: GrantFiled: June 3, 2011Date of Patent: November 27, 2012Assignee: Applied Materials, Inc.Inventors: DongQing Li, Jingmei Liang, Nitin K.

Publication number: 20120177846Abstract: Methods of forming silicon oxide layers are described. The methods include concurrently combining plasma-excited (radical) steam with an unexcited silicon precursor. Nitrogen may be supplied through the plasma-excited route (e.g. by adding ammonia to the steam) and/or by choosing a nitrogen-containing unexcited silicon precursor. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate. The oxygen content of the silicon-oxygen-and-nitrogen-containing layer is then increased to form a silicon oxide layer which may contain little or no nitrogen. The increase in oxygen content may be brought about by annealing the layer in the presence of an oxygen-containing atmosphere and the density of the film may be increased further by raising the temperature even higher in an inert environment.Type: ApplicationFiled: September 19, 2011Publication date: July 12, 2012Applicant: Applied Materials, Inc.Inventors: DongQing Li, Jingmei Liang, Xiaolin Chen, Nitin K.
