摘要: A gas delivery apparatus and method for directing a flow of gas to the edge of a substrate at an angle to the radial direction of the substrate is provided. The apparatus directs the gas from a gas opening, over a plurality of grooves that are angled relative to a radial line originating at a center of the gas delivery apparatus. Subsequently, the gas is flowed over a portion of the substrate to prevent reactive gases from depositing on selective portions of the substrate.
