• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Materials Science, Physics, or related field.
• 3–8+ 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.

Nice To Haves

• 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).

Responsibilities

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• Work closely with process engineering, quality, manufacturing, and maintenance teams.
• Support cross-functional yield improvement initiatives and failure analysis efforts.
