• Perform preventive maintenance (PM), corrective maintenance (CM), and tool recovery activities

• Troubleshoot complex issues related to process chambers, gas delivery, vacuum systems, heaters, RF/plasma, and temperature control

• Support process qualification, recipe tuning, and chamber matching in collaboration with process engineers

• Diagnose and resolve particle, uniformity, thickness, and defect-related issues

• Perform chamber cleans, kit changes, seasoning, and tool calibration

• Support tool installation, upgrades, relocations, and de-installation activities

• Analyze equipment logs and trends to improve tool stability, yield, and uptime

• Provide detailed service reports and root cause analysis (RCA) documentation

• Act as a technical interface between customer, factory support, and applications teams

• Ensure strict adherence to fab safety, EHS, and cleanroom procedures

Required Qualifications

• Diploma or Bachelor's degree in Mechanical, Electrical, Mechatronics, Electronics, or related engineering discipline

  • Vacuum systems (dry pumps, turbo pumps, throttle valves)

  • Gas delivery systems (MFCs, valves, gas panels)

  • RF generators, match networks, plasma diagnostics

  • Temperature control (heaters, thermocouples, ESC if applicable)

• Ability to read and interpret electrical schematics, P&IDs, and mechanical drawings

Preferred Qualifications

• Experience in high-volume 8-inch manufacturing fabs

• Strong background in chamber matching, particle reduction, and defect troubleshooting

• Familiarity with AMAT software, GUI, and log analysis tools

• Experience working with customer process engineers during ramp or yield improvement phases

• Willingness to support shift work, on-call rotation, and occasional overtime

Soft Skills

• Strong problem-solving and analytical mindset

• Clear communication skills for customer-facing roles

• Ability to work independently with minimal supervision

• Team-oriented with a strong sense of ownership and accountability

Location & Work Conditions
