Formulate models of plasma reactor systems for wafer fabrication Work with process and hardware design engineers to model and simulate Multiphysics problems involving plasmas, heat and mass transfer, electromagnetics at the reactor level as well as wafer level Find root-causes, optimize process and hardware design with the aid of a combination of simulation and modeling tools Simplify complex phenomena into solvable models that capture the essence of the physics Take the initiative to address the limitations in full scale plasma simulation when needed, and adopt numerical methods that speed up/augment the physics based models Design experiments to validate and refine the current models based on tool and wafer measurements Commu
