Job summary

Applied Optoelectronics, Inc. (AOI) seeks a Yield Engineer to join the Process Integration group at its Sugar Land facility. You will analyze wafer fabrication, equipment, metrology, device-test, and reliability data to identify yield trends and improvement opportunities.

Collaboration with Fab, R&D, Equipment Engineering, Quality, Test, and Reliability is essential. The role requires strong statistical analysis, DOE planning, and the ability to translate findings into action.

Qualifications

• Bachelor's degree in a technical field (EE, MSE, ChemE, Physics, Statistics)
• 3+ years in semiconductor manufacturing, process/ yield engineering, or reliability
• Strong knowledge of statistical data analysis (SPC, charts, Cp/Cpk, DOE)
• Experience with JMP or similar software for manufacturing-data analysis
• Ability to translate statistics into practical process actions
• Understanding of semiconductor fabrication processes, metrology, and controls
• Experience investigating yield loss and process excursions
• Ability to collaborate with Fab, R&D, Equipment Eng, Quality, Test, Reliability

Responsibilities

• Analyze fab process, equipment, metrology, yield, and reliability data to identify trends and sources of variation
• Monitor yield by product, process step, tool, recipe, lot, and wafer over time
• Develop and maintain SPC charts for critical parameters and product characteristics
• Evaluate Cp, Cpk, and other metrics; work with process owners to improve capability
• Plan and analyze designed experiments to improve performance, stability, yield, and reliability
• Define yield metrics and data analysis plans with process owners and Manufacturing Data Engineer
• Establish process controls and reaction plans for critical parameters
• Identify abnormal behavior and support investigations of excursions
• Lead or support yield-loss investigations using wafer maps, defect data, and test results
• Transfer new products/processes to manufacturing with proper controls and yield monitoring
• Collaborate with Quality and Reliability to connect fab conditions with burn-in and product performance
• Prioritize yield-loss mechanisms by impact and evidence
• Recommend corrective actions and verify effectiveness via follow-up data and experiments
• Prepare yield reports, trend charts, wafer maps, DOE summaries, and technical presentations
• Document investigation results, improvements, actions, and lessons learned
