You will work closely within R&D; organization and Manufacturing teams to plan and execute characterization activities, analyze data, identify trends and root causes, and communicate findings to support informed technical decisions and technology roadmap development.
Key Responsibilities
- Perform data analysis and statistical evaluation of parametric test, TEG,
and wafer-level characterization results.
- Support the planning and execution of electrical characterization and parametric testing activities for GaN power technologies.
- Analyze measurement data to identify trends, variability, anomalies, failure mechanisms, and opportunities for process and device performance improvement.
- Correlate electrical results with device architecture, process integration, and physical mechanisms governing GaN device operation.
- Investigate key device parameters such as threshold voltage, dynamic RDS(on), leakage currents, breakdown voltage, current collapse, trapping effects, and switching-related figures of merit.
- Support technology development by providing insights into device performance, variability, robustness, and reliability through characterization data analysis.
- Collaborate with R&D; and Manufacturing teams to identify root causes and drive corrective actions.
- Prepare clear technical reports and communicate findings to stakeholders across R&D; and Operations.
- Apply statistical methods and data visualization techniques using JMP, Excel, Python, and other data analysis tools.
- Contribute to the definition and optimization of characterization methodologies, test structures, and monitoring strategies for GaN technologies.
