MOCVD Operator, Production

Location: Alhambra, CA (Onsite)

Position Summary

The MOCVD Operator position is responsible for daily MOCVD operation, material measurement and data record. This position will also involve equipment maintenance activities, environmental sustaining and strictly complying with the clean room rules. The role requires teamwork, efficiency orientation, quality pursuit, and hardworking.

Responsibilities

• MOCVD Daily Operations: Check MOCVD room temperature, MO chiller temperature, pressure of H₂, N₂, hydride gas, MO consumption. Ensure everything is normal before MOCVD growth.
• Execute wafer etching cleaning, loading, unloading, recipe loading/running.
• Perform characterization with golden wafer, and enter calibration data to the metrology SPC sheet.
• Perform characterization with epi wafer: PL mapping, XRD rocking curve, ECV doping profiling.
• Input MOCVD process, equipment parameters, and wafer characterization results on daily schedule sheet.
• Record re‑growth information, sign, and date the traveler.
• Inspect wafer surface and record particle count.
• Follow clean‑room rules and report any process or equipment issues to the supervisor promptly.
• Provide suggestions on improving process quality and working efficiency.
• MOCVD Process Sustaining and Equipment Maintenance: Update inventory of InP substrate, base wafer, and chemicals.
• Engage MO bubbler change, process gas cylinder change, and hardware replacement such as pump, MFC, PC, valve, etc.
• Maintain a clean working environment: clean wet bench, workstation, desktop, and organize maintenance tools and spare parts.
• Clean and suction load lock, chamber view port, and gate valve periodically to reduce particle defects of the epi wafer.
• Support engineer to refurbish MOCVD chamber, change particle filter, P₄ trap, and exhaust absorber.
• Execute preventive maintenance procedures and perform basic troubleshooting.

Minimum Qualifications

• Associate's degree in Electronics, Semiconductor Technology, or related technical field preferred; OR high school diploma with relevant technical training and certification.
• 3–5 years of hands‑on experience in mechanical, electronic, semiconductor fabrication operations.
• Extensive knowledge of cleanroom operations, safety protocols, and contamination control.
• Experience with wafer handling and high‑vacuum equipment maintenance.
• Strict implementation of cleanroom protocols, safety procedures, and particle contamination control.
• Excellent attention to detail and continuous pursuit of wafer operation improvement.
• Effective communication and teamwork skills in a multi‑shift manufacturing environment.
• Ability to work independently with limited supervision on critical wafer growth steps.
• Willingness to work night shift, weekends as required by epi growth demand.
• Physical ability to stand for extended periods, wear full cleanroom gowning, and work in a controlled environment.

Pay

Estimated pay range: $24 – $35 per hour, based on qualifications, skills, education, experience, location, and total compensation considerations.
