  • Publication number: 20260029784
    Abstract: A selection of manufacturing equipment associated with a current fabrication process of a manufacturing environment is received. A respective eco-efficiency model corresponding to at least one of the selected manufacturing equipment is identified from a set of eco-efficiency models. Each of the set of eco-efficiency models represents a prior environmental resource consumption of a prior fabrication process involving a respective manufacturing equipment component. Values for one or more process parameters for the current fabrication process that will reduce environmental resource consumption of the current fabrication process when run using the selected manufacturing equipment are determined based on the identified respective eco-efficiency model. The determined values for the one or more process parameters are applied to the current fabrication process.

  • Patent number: 12473639
    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.
