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 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

• Bachelors degree in Electrical Engineering Mechanical Engineering Materials Science Physics or related field.
• 38 years of experience in semiconductor or photonics manufacturing.
• Hands-on experience with lithography equipment (steppers scanners track systems).
• Strong understanding of photolithography fundamentals including resist processing alignment and exposure.
• Experience working in a cleanroom environment.

Preferred Qualifications

• Experience in III-V semiconductor or photonics device fabrication (e.g. lasers VCSELs optical components).
• Familiarity with compound semiconductor processes (InP GaAs).
• Experience with advanced optical alignment and precision patterning.
• Knowledge of optical metrology CD-SEM overlay and defect inspection tools.
• Experience with high-mix high-precision manufacturing environments.
• Programming/analysis skills (Python JMP MATLAB).

Key Skills & Competencies

• Strong analytical and troubleshooting capability in precision equipment
• Attention to detail in high-sensitivity optical processes
• Ability to work in a high-mix fast-paced production environment
• Effective communication across engineering and manufacturing teams
• Continuous improvement mindset with focus on yield and quality

Work Environment

• Semiconductor cleanroom environment supporting photonics device manufacturing
• Requires strict adherence to contamination control and safety procedures
• May include occasional off-hours or on-call support for critical tools
