Technical Support Engineer - ES

Focus on correlating wafer yield outcomes with Tokyo Electron etch plasma system process data.

About the role

The Technical Support Engineer analyzes wafer yield data alongside Tokyo Electron etch plasma system signals to improve wafer yield and manufacturing metrics. The role develops data-driven insights and models to identify root causes and support continuous process optimization for etch-based steps.

What you'll do

• Build analytics that correlate wafer yield outcomes with Tokyo Electron etch plasma system process data and equipment parameters.
• Develop models and feature sets that capture relationships between plasma and etch behavior and manufacturing metrics, including yield, defect trends, and process stability.
• Create automated dashboards and reporting to track process performance over time and by tool or recipe lot.
• Perform data preparation, validation, standardization, and alignment of recipe and equipment events with wafer results.
• Support root-cause investigations using statistical and machine learning approaches to explain performance shifts and yield excursions.
• Translate analytic findings into actionable guidance for process engineering teams, such as recipe tuning suggestions and monitoring thresholds.

What you'll need

• Bachelor's degree in Engineering or a related field.
• Experience developing or optimizing dry etch processes and assessing their manufacturing capabilities.
• Experience with manufacturing process analytics, working with production yield data, and handling equipment process logs.
• Experience with data engineering and analytics, including building datasets from equipment and wafer-level data, time alignment, and handling noisy signals.
• Proficiency with machine learning and advanced statistical analysis for process monitoring, correlation, and prediction.
• Experience analyzing datasets to extract insights, visualizing data, and translating findings into actionable recommendations.
