  • Strong interpersonal skills and cultural sensitivity, with the ability to work in a fast-paced, diverse environment.
  • Ability to work in a cleanroom environment.
  • Bachelor’s degree in engineering or a related field; mechanical and electrical engineering are preferred.
  • One to five years of field service engineering experience.

Responsibilities

  • Install and maintain semiconductor manufacturing equipment, including photolithography, chemical vapor deposition, physical vapor deposition, etch, diffusion, implant, wirebond, flip-chip, die-attach, molding, and testing tools.
  • Complete a 6-to-18-month intensive technical training program in Miyagi, Japan as on-the-job work and training.
  • Maintain RF generators, vacuum pumps, and gas delivery systems to ensure high uptime for plasma etch reactors.
  • Diagnose and repair complex electromechanical and pneumatic systems.
  • Optimize chamber-cleaning procedures and preventive-maintenance schedules to support selectivity and profile control.
  • Troubleshoot laser systems, optical alignments, robotics, and high-precision stages.
  • Develop, implement, and optimize preventive-maintenance programs to increase equipment availability to the targeted 90–95%+ and reduce mean time between failures.
  • Install and operationally qualify new capital equipment, coordinating with vendors and process engineering teams.
  • Ensure maintenance and operating procedures comply with environmental, health, and safety regulations and cleanroom protocols.
  • Translate documents, emails, tickets, and presentations between Mandarin and English, and provide real-time interpretation during meetings and calls.

  • Handle inquiries, disputes, and service requests from Mandarin-speaking customers by phone, email, or chat.
  • Identify communication gaps and suggest improvements to support quality assurance.
  • Install and maintain semiconductor manufacturing equipment and fine-tune photolithography, etch, chemical vapor deposition, physical vapor deposition, atomic layer deposition, diffusion, and implant processes to improve device yield, efficiency, and performance.
  • Identify root causes of process deviations, defects, and yield issues, and implement corrective actions in a high-volume manufacturing environment.
  • Develop recipes for plasma etch systems to meet profile and selectivity specifications.
  • Ensure precise critical dimensions are maintained after processing.
  • Oversee installation, calibration, corrective maintenance, and preventive maintenance of photolithography, etch, chemical vapor deposition, physical vapor deposition, atomic layer deposition, diffusion, and implant equipment, including steppers, scanners, track systems, and metrology tools.
