Abstract
An apparatus for providing processing gases to a process chamber with improved uniformity is disclosed. One embodiment provides a gas delivery assembly. The gas delivery assembly includes a hub, a nozzle, and one or more gas diffusers disposed in the nozzle. The nozzle has a cylindrical body with a side wall and a top surface. A plurality of injection passages are formed inside the nozzle to deliver processing gases into the process chamber via a plurality of outlets disposed in the side wall. The injection passages are configured to direct process gases out of each outlet disposed in the side wall in a direction which is not radially aligned with a centerline of the hub.
