Lithography Equipment Engineer
Job Summary
Lumentum is seeking a Lithography Equipment Engineer to support high-volume manufacturing of advanced photonic and optoelectronic devices. This role focuses on sustaining and improving lithography equipment used in the fabrication of III-V semiconductor devices, lasers, and optical components. The engineer will ensure tool performance, process stability, and yield optimization in a fast-paced, precision-driven environment.
Key Responsibilities
Equipment Ownership & Sustaining - Serve as the primary owner for lithography tools, including steppers/aligners and coat/develop track systems. Maintain high tool uptime and reliability to support production of photonic devices (e.g., lasers, modulators, optical chips). Perform advanced troubleshooting on optical exposure systems, alignment modules, and resist processing equipment.
Process & Device Support - Partner with process and device engineers to support fabrication of III-V photonics devices. Optimize lithography performance for critical parameters such as: Linewidth (CD) control, Overlay accuracy, Defectivity reduction. Support new product introductions (NPI) and technology transfers.
Continuous Improvement - Drive initiatives to improve yield, tool throughput, and cost efficiency. Lead projects to reduce variation and improve pattern fidelity for optical device structures. Implement equipment upgrades, recipe improvements, and automation enhancements.
Installation & Qualification Support - Support installation, bring-up, and qualification of new lithography tools and upgrades. Collaborate with OEM vendors (e.g., ASML, Canon, Nikon, TEL) on tool performance and issue resolution. Execute tool matching and cross-fab standardization where applicable.
Preventive Maintenance & Calibration - Develop and refine PM procedures to ensure tool precision and stability. Ensure proper calibration of optical systems, alignment stages, and exposure settings. Maintain compliance with cleanroom and EHS standards.
Data Analysis & Problem Solving - Analyze SPC data, fault logs, and yield metrics to identify trends and root causes. Use structured problem-solving tools (RCA, 8D, DOE) to resolve recurring issues. Leverage data analysis tools (JMP, Python, Excel) to drive decision-making.
Cross-functional Collaboration - Work closely with process engineering, quality, manufacturing, and maintenance teams. Support cross-functional yield improvement initiatives and failure analysis efforts.
Required Qualifications
