    摘要: A method is provided for forming high dielectric constant (high-k) films for semiconductor devices. According to one embodiment, a metal-carbon-oxygen high-k film is deposited by alternately and sequentially exposing a substrate to a metal-carbon precursor and near saturation exposure level of an oxidation source containing ozone. The method is capable of forming a metal-carbon-oxygen high-k film with good thickness uniformity while impeding growth of an interface layer between the metal-carbon-oxygen high-k film and the substrate. According to one embodiment, the metal-carbon-oxygen high-k film may be treated with an oxidation process to remove carbon from the film.

    摘要: A method and system for monitoring status of a system component during a process. The method includes exposing a system component to a reactant gas during a process, where the reactant gas is capable of etching the system component material to form an erosion product, and monitoring release of the erosion product during the process to determine status of the system component. Processes that can be monitored include a chamber cleaning process, a chamber conditioning process, a substrate etching process, and a substrate film formation process. The system component can be a consumable system part such as a process tube, a shield, a ring, a baffle, an injector, a substrate holder, a liner, a pedestal, a cap cover, an electrode, and a heater, any of which can further include a protective coating. The processing system includes the system component in a process chamber, a gas injection system for introducing the reactant gas, a chamber protection system for monitoring the status of the system component, and a controller for controlling the processing system in response to the status.

    摘要: A method and system are described for increasing the tensile stress in thin films formed on a substrate, such as silicon nitride films. The thin film may be a planar film, or a non-planar film, such as a nitride film formed over a NMOS gate. The thin film is exposed to electro-magnetic (EM) radiation, such as EM radiation having a wavelength component less than about 500 nm. The EM source can include a multi-frequency source of radiation. Additionally, the source of radiation is collimated in order to selectively treat regions of a non-planar film.

A surface of said substrate is exposed to oxygen radicals formed by ultraviolet (UV) radiation induced dissociation of a first process gas comprising at least one molecular composition comprising oxygen to form an oxide film. The oxide film is exposed to nitrogen radicals formed by plasma induced dissociation of a second process gas comprising at least one molecular composition comprising nitrogen to nitridate the oxide film to form the interfacial layer. A high-k dielectric layer is formed on said interfacial layer.
