• Own and drive yield improvement initiatives, identifying key yield limiters and implementing sustainable solutions.

• Use structured problem-solving methodologies (e.g., 8D, DMAIC, root cause analysis) to resolve yield excursions using inline data, electrical test data, failure analysis, and direct fab observations.

• Analyze and interpret data from defect inspection and metrology tools to identify, characterize, and eliminate yield-limiting defects.

• Partner with process engineering teams to optimize process windows, improve uniformity, and enhance overall device performance.

• Lead design of experiments (DOE) and leverage statistical process control (SPC) and advanced analytics to drive continuous process improvement.

• Serve as a cross-functional technical leader, collaborating with fab operations, equipment engineering, test, and R&D to implement and validate process changes.

• Own flying probe electrical test processes, including data analysis, reporting, and automation of test outputs.

• Monitor rework trends and scrap drivers, implementing process improvements to reduce rework rates and improve cycle time.

• Support technology transfer and ramp from R&D into high-volume manufacturing, ensuring stable yield and manufacturability.

• Develop and maintain process integration documentation, including flows, specs, and control strategies.

• Lead and mentor cross-functional teams in data-driven problem solving and best practices.
