Co-Evaporation Engineer

The Engineer using co-evaporation or sputter vacuum deposition is responsible forthe operation,troubleshooting and improvement of thin-film deposition processes in roll-to-roll (R2R) vacuum equipment.

The focus of this role is on preparing, maintaining, repairing and running large physical vapor deposition equipment in a roll-to-roll format to successfully produce thin film product at large scale. The engineer will work closely with equipment, and maintenance engineers, process engineers for other process steps, backend, and production teams to deliver manufacturable thin-film product.

• Prepare, operate, and maintainco-evaporation or sputter equipment for thin-film deposition in roll-to-roll vacuum systems.

• Support the modification and repair of large-area R2R vacuum deposition equipment, including vacuum sensors and pressure gauges, vacuum pumps and valves.

• Rebuild and install deposition sources that include complex mechanical parts, specialty materials, and electrical connections.

• Diagnose problems based on close examination of mechanical assemblies, process characteristics and software diagnostics.

• Observe and control process parameters such as deposition rates, substrate temperature, vacuum conditions, and web speed to assure proper operation or make setpoint corrections.

• Troubleshoot process deviations related to composition, uniformity, adhesion, and device performance.

• Collaborate with device and backend teams to ensure deposition processes are compatible with interconnection, lamination, and module assembly.

• Support scale-up from lab or pilot systems to high-volume roll-to-roll production.

• Develop and document process recipes, operating procedures, and control limits.

• Support performance improvement initiatives targeting efficiency, yield, and reproducibility.

• MS in Materials Science, Physics, Electrical Engineering, or related technical field(or BS with significant relevant industry experience).

• Minimum 5 years of hands-on experience in thin-film vacuum deposition.

• Strong mechanical aptitude and troubleshooting ability for complex vacuum deposition equipment.

• Experience working with vacuum systems, vacuum gauges, valves, and control methods.

• Ability to work effectively in a multidisciplinary manufacturing and R&D environment.

• Excellent communication and organizational skills.

• Experience with complex deposition hardware for large-area or high-throughput systems.

• Hands-on experience with troubleshooting PLC controlled equipment.

• Experience operating closed-loop or real-time process control for semiconductor deposition.

• Experience designing and building equipment for thin film semiconductor deposition and thermal processes.

• Skills with mechanical design and electrical systemsdiagnosis and repair.
