The Semiconductor Equipment Maintenance Supervisor is a hands-on working supervisor responsible for the safe, reliable, and compliant maintenance of semiconductor processing equipment supporting a 3-inch indium phosphide/gallium arsenide (InP/GaAs) compound-semiconductor fab and an 8-inch silicon fab. The role leads equipment maintenance technicians and service providers while actively supporting advanced troubleshooting, preventive and corrective maintenance, equipment recovery, upgrades, installations, and lifecycle planning.

The supervisor partners with Equipment Engineering, Process Engineering, Manufacturing Operations, Environmental Health and Safety (EH&S), suppliers, and facilities interfaces to maximize tool availability, process capability, and production readiness across both fabs. This role does not own base-building or central facility systems.

• Hands-on technical supervision: Direct daily maintenance activity while personally assisting with complex diagnostics, repairs, calibrations, equipment recovery, and safe return-to-production.
• Team leadership: Assign priorities, balance workloads, establish shift and on-call coverage, coach technicians, verify work quality, and develop technical capability through equipment-specific qualification and cross-training plans.
• Process-equipment ownership: Lead maintenance support for equipment used in epitaxy, wet and dry etch, thin-film deposition, diffusion and thermal processing, ion implantation, photolithography, wafer cleaning, plating, metrology, inspection, wafer thinning, dicing, and related fab operations.
• Compound-semiconductor equipment: Support specialized InP/GaAs tools and subsystems involving toxic, pyrophoric, corrosive, and hazardous process materials, including process chambers, gas panels, chemical delivery interfaces, vacuum systems, point-of-use abatement, robotics, controls, and safety interlocks.
• Silicon-fab equipment: Sustain 8-inch silicon processing tools in a production environment through disciplined troubleshooting, maintenance execution, recovery, and obsolescence planning.
• Preventive and predictive maintenance: Develop and execute maintenance plans based on equipment criticality, process risk, condition, manufacturer guidance, failure history, and production schedules; improve PM effectiveness through data analysis.
• Corrective maintenance and escalation: Lead structured fault isolation for mechanical, electrical, electronic, software, robotics, motion-control, RF, vacuum, thermal, chemical, gas-delivery, and instrumentation issues; coordinate supplier escalation when needed.
• Production recovery: Prioritize tool-down response, establish containment and recovery plans, communicate estimated restoration timing, and confirm maintenance completion before process qualification and release.
• Work management: Control work orders, backlog, labor planning, lockout/tagout, parts, vendor activities, maintenance procedures, calibration records, equipment logs, and post-maintenance verification through the site CMMS and approved systems.
• Safety and compliance: Enforce hazardous-energy control, electrical safety, chemical and gas safety, radiation or laser controls where applicable, cleanroom protocols, job hazard analyses, and equipment-specific safe-work procedures.
• Equipment installations and upgrades: Support tool selection, design reviews, installation, hookup coordination, acceptance testing, commissioning, decommissioning, relocation, and production handoff; ensure maintainability and service requirements are addressed.
• Reliability improvement: Lead root-cause analysis, corrective actions, bad-actor equipment reviews, and…
