Day-to-Day Responsibilities
Develop and tune process recipes for steps such as photolithography, etching, deposition, oxidation, diffusion and ion implantation.
Monitor wafer-level and tool-level data to spot drift, yield loss or defects, and trace their root causes.
Plan and run design-of-experiments (DOE) trials to widen the process window and improve yield.
Work with equipment engineers to maintain, troubleshoot and re-qualify process tools after servicing.
Follow cleanroom protocols, safety rules and the handling procedures for gases and chemicals.
Document process changes and support change control, audits and quality systems.
Coordinate with device, integration and test teams to move new products into volume production.
