Title: Innovations by Inventor Feng Bi
Introduction
Feng Bi is a notable inventor based in Cupertino, CA, with a focus on advancements in semiconductor processing technologies. He holds a total of 5 patents that reflect his innovative contributions to the field.
Latest Patents
One of his latest patents is a "Showerhead with air-gapped plenums and overhead isolation gas distributor." This invention provides showerheads designed for independently delivering different, mutually-reactive process gases to a wafer processing space. The design includes a first gas distributor with multiple plenum structures separated by gaps, along with a second gas distributor positioned above it. The isolation gas from the second distributor flows down onto the first, creating an isolation gas curtain that prevents process gases from parasitically depositing on other plenum structures.
Another significant patent is for a "Cleaning process for removing boron-carbon residuals in processing chamber at high temperature." This method involves using water vapor plasma treatment to remove a boron-carbon layer from the surface of a processing chamber. The process includes positioning the pedestal at varying distances from the showerhead and exposing the boron-carbon layer to plasma processes that generate water vapor and carrier gases.
