• Conduct equipment calibration, alignment, leak checks, safety checks, functional testing, and post-maintenance verification.
• Respond promptly to equipment breakdowns and production interruptions, restoring tools to service safely and efficiently.
• Investigate recurring failures and implement corrective and preventive actions to improve equipment uptime, reliability, and maintenance effectiveness.
• Work with Process Engineering to resolve equipment-related defects, contamination issues, process excursions, and wafer-handling problems.
• Support equipment installation, hook-up, start-up, commissioning, acceptance testing, qualification, upgrades, retrofits, and relocation.
• Maintain accurate maintenance records, equipment logs, parts-consumption data, troubleshooting reports, and shift-handover information.
• Develop and improve preventive-maintenance procedures, troubleshooting guides, job plans, and equipment work instructions.
• Coordinate with LAM Research, specialist service providers, and other vendors for technical escalation, parts support, and field modifications.
• Identify critical spare parts and support inventory planning, component refurbishment, and equipment-obsolescence management.
• Train and guide technicians in equipment operation, maintenance procedures, troubleshooting methodology, and safety practices.
• Follow all cleanroom, chemical-handling, hazardous-waste, lockout/tagout, and environmental health and safety requirements.
• Support rotating shifts, weekend coverage, on-call requirements, and urgent production recovery activities as required. Minimum Qualifications
• Diploma, associate degree, bachelor’s degree, or equivalent technical qualification in Electrical, Electronics, Mechanical, Mechatronics, Chemical, Manufacturing, or Engineering Technology.
• Typically 3–7 years of hands-on semiconductor equipment maintenance or equipment engineering experience.
• Demonstrated maintenance and troubleshooting experience with SEZ equipment currently supported under LAM Research and/or Hitachi CD SEM Metrology Equipment.
• Practical knowledge of wet-processing equipment, single-wafer processing, wafer handling, chemical dispensing, fluid delivery, and exhaust systems.
• Strong understanding of electrical, mechanical, pneumatic, robotic, sensor, and software-controlled equipment systems.
• Ability to read and interpret electrical schematics, mechanical drawings, piping diagrams, equipment manuals, and troubleshooting documentation.
• Experience using multimeters, pressure and flow measurement instruments, calibration tools, leak-detection equipment, and standard maintenance tools.
• Proven ability to perform systematic troubleshooting and root-cause analysis in a production fab.
• Good written and verbal communication skills in English.
• Ability to work effectively in multicultural engineering and manufacturing teams.
• Willingness to work rotating shifts and provide on-call or weekend support according to fab requirements. Preferred Qualifications
• Advanced experience with SEZ / LAM wet clean, wafer-backside treatment, bevel-processing, spin-processing, or related platforms and/or Hitachi CD SEM Metrology Equipment advanced maintenance use cases.
• Experience troubleshooting wafer-transfer robots, aligners, end effectors, cassette stations, and automated material-handling interfaces.
• Knowledge of chemical compatibility, contamination control, filtration, dispense accuracy, exhaust management, and leak prevention.
• Experience with SPC, FDC, equipment-performance monitoring, maintenance-management systems, and reliability-improvement methods.
• Experience supporting major equipment overhauls, chamber or module rebuilds, equipment conversions, and field upgrades.
• Previous experience working directly with LAM Research or SEZ technical-support teams.
• Mandarin language capability is advantageous for Taiwan-based assignments but is not mandatory unless required by the client site. Physical and Work Requirements
• Ability to work in a semiconductor cleanroom while wearing required personal protective equipment.
• Ability to stand, walk, bend, kneel, and work within confined equipment areas for extended periods.
• Ability to handle equipment components and maintenance tools within applicable site lifting requirements.
• Ability to work safely around production chemicals, automated systems, energized equipment, and fluid-delivery systems.
• Compliance with all applicable work-authorization, immigration, medical, and client-site access requirements for Taiwan.
