Publication number: 20170365480Abstract: Embodiments described herein generally relate to enable the formation of a metal gate structure with a reduced effective oxide thickness over a similar structure formed via conventional methods. A plasma hydrogenation process followed by a plasma nitridization process is performed on a metal nitride layer in a film stack, thereby removing oxygen atoms disposed within layers of the film stack and, in some embodiments eliminating an oxygen-containing interfacial layer disposed within the film stack. As a result, an effective oxide thickness of the metal gate structure is reduced with little or no accompanying flatband voltage shift. Further, the metal gate structure operates with an increased leakage current that is as little as one quarter the increase in leakage current associated with a similar metal gate structure formed via conventional techniques.Type: ApplicationFiled: February 24, 2017Publication date: December 21, 2017Inventors: Johanes S. SWENBERG, Wei LIU, Houda GRAOUI, Shashank SHARMA

Publication number: 20170236702Abstract: Embodiments of the present disclosure generally relate to methods for forming a high-k gate dielectric in a transistor. The high-k gate dielectric may be formed by introducing a fluorine containing gas into a processing chamber during the deposition of the high-k gate dielectric in the processing chamber. In one embodiment, the high-k gate dielectric is formed by an ALD process in a processing chamber, and a fluorine containing gas is introduced into the processing chamber during one or more stages of the ALD process. Fluorine ions, molecules or radicals from the fluorine containing gas (may be activated by a plasma) can fill the oxygen vacancies in the high-k dielectric.Type: ApplicationFiled: January 23, 2017Publication date: August 17, 2017Inventors: Johanes S. SWENBERG, Linlin WANG, Wei LIU

Patent number: 9023700Abstract: Methods and apparatus for selective one-step nitridation of semiconductor substrates is provided. Nitrogen is selectively incorporated in silicon regions of a semiconductor substrate having silicon regions and silicon oxide regions by use of a selective nitridation process. Nitrogen containing radicals may be directed toward the substrate by forming a nitrogen containing plasma and filtering or removing ions from the plasma, or a thermal nitridation process using selective precursors may be performed. A remote plasma generator may be coupled to a processing chamber, optionally including one or more ion filters, showerheads, and radical distributors, or an in situ plasma may be generated and one or more ion filters or shields disposed in the chamber between the plasma generation zone and the substrate support.Type: GrantFiled: June 9, 2014Date of Patent: May 5, 2015Assignee: Applied Materials, Inc.Inventors: Udayan Ganguly, Theresa Kramer Guarini, Matthew Scott Rogers, Yoshitaka Yokota, Johanes S. Swenberg, Malcolm J. Bevan

Patent number: 8846509Abstract: The present invention generally relates to methods of forming substrates using remote radical hydride doping. The methods generally include remotely activating a gas and introducing activated radicals of the gas into a chamber. The activated radicals may be activated hydride radicals of a gas such as diborane (B2H6), phosphine (PH3), or arsine (AsH3) which are utilized to incorporate an element such as boron, phosphorus, or arsenic into a substrate having a surface temperature between about 400 degrees Celsius and about 1000 degrees Celsius. Alternatively, the activated radicals may be activated radicals of an inert gas. The activated radicals of the inert gas are introduced into a chamber having a dopant-containing gas, such as diborane, phosphine, or arsine, therein. The activated radicals of the inert gas activate the dopant-gas and incorporate dopants into a heated substrate located within the chamber.Type: GrantFiled: November 14, 2012Date of Patent: September 30, 2014Assignee: Applied Materials, Inc.Inventors: Christopher S. Olsen, Johanes S. Swenberg

Publication number: 20120222618Abstract: Methods and apparatus for processing semiconductor substrates are described. A processing chamber includes a substrate support with an in-situ plasma source, which may be an inductive, capacitive, microwave, or millimeter wave source, facing the substrate support and a radiant heat source, which may be a bank of thermal lamps, spaced apart from the substrate support. The support may be between the in-situ plasma source and the radiant heat source, and may rotate. A method or processing a substrate includes forming an oxide layer by exposing the substrate to a plasma generated in a process chamber, performing a plasma nitridation process on the substrate in the chamber, thermally treating the substrate using a radiant heat source disposed in the chamber while exposing the substrate to oxygen radicals formed outside the chamber, and forming an electrode by exposing the substrate to a plasma generated in the chamber.Type: ApplicationFiled: July 28, 2011Publication date: September 6, 2012Applicant: APPLIED MATERIALS, INC.Inventors: Christopher Olsen, Canfeng Lai, Sundar Ramamurthy, Johanes S.
