Abstract
One or more embodiments described herein generally relate to methods and systems for forming films on substrates in semiconductor processes. In embodiments described herein, a process system includes different materials each contained in separate ampoules. Each material is flowed into a separate portion of a showerhead contained within a process chamber via a heated gas line. From the showerhead, each material is flowed on to a substrate that sits on the surface of a rotating pedestal. Controlling the mass flow rate out of the showerhead and the rotation rate of the pedestal helps result in films with desirable material domain sizes to be deposited on the substrate.
