  • Patent number: 11915918
    Abstract: A physical vapor deposition processing chamber is described. The processing chamber includes a target backing plate in a top portion of the processing chamber, a substrate support in a bottom portion of the processing chamber, a deposition ring positioned at an outer periphery of the substrate support and a shield. The substrate support has a support surface spaced a distance from the target backing plate to form a process cavity. The shield forms an outer bound of the process cavity. In-chamber cleaning methods are also described. In an embodiment, the method includes closing a bottom gas flow path of a processing chamber to a process cavity, flowing an inert gas from the bottom gas flow path, flowing a reactant into the process cavity through an opening in the shield, and evacuating the reaction gas from the process cavity.

  • Patent number: 11832533
    Abstract: Methods and apparatuses for forming an encapsulation bilayer over a chalcogenide material on a semiconductor substrate are provided. Methods involve forming a bilayer including a barrier layer directly on chalcogenide material deposited using pulsed plasma plasma-enhanced chemical vapor deposition (PP-PECVD) and an encapsulation layer over the barrier layer deposited using plasma-enhanced atomic layer deposition (PEALD). In various embodiments, the barrier layer is formed using a halogen-free silicon precursor and the encapsulation layer deposited by PEALD is formed using a halogen-containing silicon precursor and a hydrogen-free nitrogen-containing reactant.

  • Patent number: 10804099
    Abstract: Methods of selectively inhibiting deposition of silicon-containing films deposited by atomic layer deposition are provided. Selective inhibition involves exposure of an adsorbed layer of a silicon-containing precursor to a hydrogen-containing inhibitor, and in some instances, prior to exposure of the adsorbed layer to a second reactant. Exposure to a hydrogen-containing inhibitor may be performed with a plasma, and methods are suitable for selective inhibition in thermal or plasma enhanced atomic layer deposition of silicon-containing films.

  • Patent number: 9589790
    Abstract: Provided herein are methods of depositing conformal silicon nitride films using atomic layer deposition by exposure to a halogen-free, N—H-bond-free, and carbon-free silicon-containing precursor such as disilane, purging of the precursor, exposure to a nitrogen plasma, and purging of the plasma at low temperatures. A high frequency plasma is used, such as a plasma having a frequency of at least 13.56 MHz or at least 27 MHz. Methods yield substantially pure conformal silicon nitride films suitable for deposition in semiconductor devices, such as in trenches or features, or for memory encapsulation.

  • Patent number: 9076646
    Abstract: The embodiments herein focus on plasma enhanced atomic layer deposition (PEALD) processes using pulsed plasmas. While conventional PEALD processes use continuous wave plasmas during the plasma exposure/conversion operation, the embodiments herein utilize a pulsed plasma during this operation to achieve a film with high quality sidewalls. Because conventional PEALD techniques result in films having high quality at the bottom and top of a feature, but low quality on the sidewalls, this increased sidewall quality in the disclosed methods corresponds to a film that is overall more uniform in quality compared to that achieved with conventional continuous wave plasma techniques.
