Wafer Fab Yield Process Engineer

The Senior Wafer Fab Yield Engineer is responsible for driving systematic yield improvement across semiconductor wafer fabrication. This position analyzes manufacturing, inline metrology, defect, wafer-level electrical test, and process data to identify yield-loss mechanisms, determine root causes, and lead implementation of sustainable corrective actions. The engineer serves as a senior technical resource connecting fab process performance to device and product yield. The role works cross-functionally with Process Engineering, Equipment Engineering, Process Integration, Product/Test Engineering, Failure Analysis, Quality, and Manufacturing to improve yield, reduce variability, and accelerate resolution of complex manufacturing problems. Responsibilities: - Lead wafer-fab yield improvement initiatives, identifying and prioritizing the dominant yield-loss mechanisms and converting analysis into actionable improvement projects. - Analyze wafer probe maps, electrical test/bin data, inline metrology, defect inspection data, equipment/process history, and lot genealogy to isolate sources of systematic and random yield loss. - Perform correlation, regression, statistical analysis, wafer spatial analysis, trend analysis, and other data-mining techniques to identify relationships between process conditions and electrical yield. - Lead complex root-cause investigations involving process excursions, recurring yield degradation, wafer-level signatures, equipment effects, materials, and process interactions. - Partner with Process and Equipment Engineering to translate yield signatures into physical process hypotheses and validate corrective actions. - Define and execute structured experiments and DOE to validate suspected yield drivers and optimize process windows. - Use SPC and process-capability analysis to identify process variation and opportunities for improved manufacturing control. - Correlate WAT, wafer sort, inline process-monitoring, defect, and manufacturing data to identify yield improvement opportunities. - Work with Failure Analysis teams to develop appropriate physical-analysis plans and translate findings into manufacturing actions. - Develop analyses and engineering reports that clearly communicate yield trends, excursions, root causes, improvement opportunities, and project status. - Lead cross-functional technical reviews for significant yield excursions and improvement programs. - Support new-product and/or technology introduction by identifying yield risks, establishing baseline performance, and accelerating learning during manufacturing ramp. - Mentor less-experienced engineers in statistical analysis, structured problem solving, yield analysis, and fab troubleshooting. - Identify opportunities to improve fab-wide yield-analysis methods, data infrastructure, and problem-solving practices. Qualifications - Bachelor's degree in Electrical Engineering, Applied Physics, or a related technical discipline. - Significant engineering experience in semiconductor wafer fabrication, preferably involving yield, process integration, process engineering, product engineering, or device engineering. - Strong understanding of semiconductor wafer fabrication processes and the relationship between process variation, device characteristics, defects, and electrical yield. - Demonstrated ability to perform statistical analysis and solve complex manufacturing problems using large manufacturing datasets. - Experience with statistical/data-analysis tools such as JMP, or comparable platforms. - Working knowledge of SPC, DOE, process capability, correlation/regression, hypothesis testing, and structured root-cause analysis. - Ability to communicate complex technical conclusions clearly to engineering and manufacturing organizations. - Demonstrated ability to lead cross-functional technical problem-solving efforts. Preferred Qualifications - Master's degree in Electrical Engineering, Applied Physics, or related discipline. - Experience correlating inline process/defect data 12 WAT/electrical data 12 wafer-sort/final yield. - Experience with wafer-map and spatial-pattern analysis. - Experience with semiconductor defect inspection and/or physical failure analysis. - Experience creating automated yield-analysis or data-mining tools. - Knowledge of semiconductor device physics and electrical test structures. - Experience supporting technology or product ramps in a high-volume wafer fabrication environment Due to the nature of this position and the required access to areas where ITAR-controlled articles and/or technical data may be present, candidates must meet the applicable U.S. person requirements for ITAR access.
