    摘要: The present invention generally provides a method for preparing an oxynitride film on a substrate. A surface of the 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 on the surface. 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 using plasma based on microwave irradiation via a plane antenna member having a plurality of slits to nitridate the oxide film and form the oxynitride film.

    摘要: A method is provided for reducing the metal content and controlling the metal depth profile of a gate dielectric layer in a gate stack. The method includes providing a substrate in a process chamber, depositing a gate dielectric layer on the substrate, where the gate dielectric layer includes a metal element. The metal element is selectively etched from at least a portion of the gate dielectric layer to form an etched gate dielectric layer with reduced metal content, and a gate electrode layer is formed on the etched gate dielectric layer.
