Publication number: 20210287955Abstract: Embodiments of the present disclosure generally relate to nitrogen-rich silicon nitride and methods for depositing the same, and transistors and other devices containing the same. In one or more embodiments, methods for depositing silicon nitride materials are provided and include heating a workpiece to a temperature of about 200° C. to about 250° C., exposing the workpiece to a deposition gas during a plasma-enhanced chemical vapor deposition process, and depositing a nitrogen-rich silicon nitride layer on the workpiece. The deposition gas contains a silicon precursor, a nitrogen precursor, and a carrier gas. A molar ratio of the silicon precursor to the nitrogen precursor to the carrier gas within the deposition gas is about 1:a range from about 4 to about 8:a range from about 20 to about 80, respectively.Type: ApplicationFiled: June 3, 2021Publication date: September 16, 2021Inventors: Rodney S. LIM, Jung Bae KIM, Jiarui WANG, Yi CUI, Dong Kil YIM, Soo Young CHOI

Patent number: 10950445Abstract: Embodiments of the present disclosure generally relate to methods and apparatus for depositing metal silicide layers on substrates and chamber components. In one embodiment, a method of forming a hardmask includes positioning the substrate having a target layer within a processing chamber, forming a seed layer comprising metal silicide on the target layer and depositing a tungsten-based bulk layer on the seed layer, wherein the metal silicide layer and the tungsten-based bulk layer form the hardmask. In another embodiment, a method of conditioning the components of a plasma processing chamber includes flowing an inert gas comprising argon or helium from a gas applicator into the plasma processing chamber, exposing a substrate support to a plasma within the plasma processing chamber and forming a seasoning layer including metal silicide on an aluminum-based surface of the substrate support.Type: GrantFiled: July 29, 2020Date of Patent: March 16, 2021Assignee: Applied Materials, Inc.Inventors: Prashant Kumar Kulshreshtha, Jiarui Wang, Kwangduk Douglas Lee, Milind Gadre, Xiaoquan Min, Paul Connors
