Responsibilities

JOB DESCRIPTION Metrology Development and Optimization

Serve as the process owner for semiconductor metrology, developing, sustaining, and optimizing measurement methods for production and process development.
Develop and optimize measurement recipes for ellipsometry, spectroscopy, reflectometry, profilometry, WLI, Nanospec, and other metrology systems.
Develop measurement methods for film thickness, RI, surface topography, step height, feature dimensions, wafer bow, and other critical process parameters.
Establish appropriate measurement locations, sampling plans, and measurement strategies to ensure accurate and representative process data.
Apply SPC, DOE, and statistical analysis to monitor and improve measurement and manufacturing processes.
Work cross-functionally with photo, etch, thin films, wet process, integration, R&D, and production teams to develop measurement solutions and troubleshoot process issues.

Equipment Ownership and Troubleshooting

Serve as the technical owner for ellipsometry, spectroscopy, reflectometry, profilometry, WLI, Nanospec, and associated metrology equipment.
Lead troubleshooting efforts for measurement excursions, equipment issues, recipe problems, and measurement correlation.
Support equipment qualification, calibration, preventive maintenance, tool matching, and continuous improvement activities.
Develop and maintain tool-to-tool correlation and matching strategies across metrology systems.
Work with equipment vendors and maintenance personnel to improve measurement performance, reliability, and uptime.
Support evaluation, selection, installation, and qualification of new metrology equipment.

Measurement System Analysis and Process Control

Develop and execute MSA and Gage R&R studies to evaluate measurement repeatability, reproducibility, accuracy, and capability.
Evaluate tool-to-tool correlation, operator effects, measurement sensitivity, sampling strategies, and other sources of measurement variation.
Establish measurement specifications, control limits, and monitoring methods.
Ensure measurement systems are capable of supporting process specifications, SPC, process capability analysis, and manufacturing requirements.
Identify and reduce sources of measurement variation to improve confidence in manufacturing data.

Automation, Recipe Management, and Data Systems

Support automated recipe download and verification for production metrology equipment.
Work with automation and equipment teams to ensure correct recipe selection, parameter control, lot/wafer tracking, and data collection.
Develop and maintain measurement limits, alarms, and fault detection rules.
Review equipment and measurement data to identify trends, excursions, and early indicators of process or equipment issues.
Support automated data collection, reporting, traceability, and integration with MES and manufacturing systems.

Yield Improvement and Manufacturing Support

Use metrology data to support root cause investigations, process characterization, yield improvement, and defect reduction.
Develop and implement improvements to increase measurement capability, reduce variation, and improve manufacturing control.
Support new product introductions, process qualifications, and technology transfers.
Develop and maintain measurement procedures, work instructions, specifications, control plans, and MSA documentation.
Train technicians and junior engineers on metrology equipment, measurement methods, troubleshooting, and best practices.
