Experience mentoring entry-level or intermediate maintenance technicians.

Responsibilities

Lead scheduled preventive maintenance and execute rapid-response corrective maintenance on CMP polishers, post-CMP cleaners, and slurry delivery loops.
Troubleshoot complex electro-mechanical, pneumatic, and fluidic subsystems to root cause using schematics, wiring diagrams, diagnostic meters, and oscilloscopes.
Dismantle, overhaul, calibrate, and reassemble critical sub-assemblies (e.g., polish heads, conditioner arms, platen drives, chemical delivery valves).
Support engineering continuous improvement projects (CIP), tool modifications, and process qualification runs.
Safely handle hazardous production materials, including slurry, corrosive chemicals, and chemical delivery line flushes, following all fab safety protocols.
Maintain comprehensive tool logs, maintenance shift handoffs, and spare parts/consumable tracking via factory CMMS.
