Patent number: 11227797Abstract: Embodiments described herein relate to methods of seam-free gapfilling and seam healing that can be carried out using a chamber operable to maintain a supra-atmospheric pressure (e.g., a pressure greater than atmospheric pressure). One embodiment includes positioning a substrate having one or more features formed in a surface of the substrate in a process chamber and exposing the one or more features of the substrate to at least one precursor at a pressure of about 1 bar or greater. Another embodiment includes positioning a substrate having one or more features formed in a surface of the substrate in a process chamber. Each of the one or more features has seams of a material. The seams of the material are exposed to at least one precursor at a pressure of about 1 bar or greater.Type: GrantFiled: November 6, 2019Date of Patent: January 18, 2022Assignee: Applied Materials, Inc.Inventors: Shishi Jiang, Kurtis Leschkies, Pramit Manna, Abhijit Mallick
