1. Role Overview

The Direct Imaging (DI) Field Service Tech. is responsible for installing, commissioning, calibrating, maintaining, and repairing high-precision Digital Direct Imaging (DI/DE/DLT) exposure systems at customer manufacturing facilities. Working with cutting-edge optical, high-precision mechanical, laser, and electronics subsystems, the engineer serves as the primary technical expert on-site to minimize tool downtime, ensure high yield/throughput, and maintain exceptional customer satisfaction.

2. Key Responsibilities

System Installation & Commissioning

• Perform on-site unboxing/uncrating, precision leveling, electrical-mechanical assembly, and system turn-up for advanced Direct Imaging Exposure equipment.
• Calibrate stage motion accuracy, optical/laser systems, and auto-alignment registration systems according to OEM engineering specifications.
• Conduct Site Acceptance Testing (SAT) and collaborate with customer process engineers to validate exposure quality and registration overlay.

Preventive/Corrective Maintenance & Tool Upgrades

• Execute scheduled Preventative Maintenance (PM) procedures that will include optic/electronic/mechanical inspection/cleaning, consumable parts replacement, stage/axis motion tuning, and system calibration
• Rapidly respond to tool down events; perform root-cause failure analysis (RCFA) on complex hardware, software, optics, and electro-mechanical issues.
• Repair or replace subassemblies such as, but not limited to UV and Visible LED / Laser sources, DMD (Digital Micromirror Device), optics, motion controllers, pneumatic systems, electronic sensors, mechanical parts, and driver modules
• Perform tool upgrades, modifications and retrofits as needed

Technical Support & Process Optimization

• Act as the technical liaison between customer engineering staff and internal R&D/Applications engineering teams.
• Troubleshoot exposure defects (e.g., line-width variation, overlay misalignment, pattern distortion) and optimize system parameters for target photoresist materials.
• Maintain cleanroom protocol compliance (Class 10/100 or ISO 4/5 environments).

Administrative & Operational Compliance

• Accurately document all service activities, field modifications, parts usage, and system histories in the Field Service Management (CRM) system in a timely manner.
• Manage local spare parts trunk stock, tool calibration cycles, and field return authorizations (RMA).
• Comply with strict cleanroom safety guidelines, Occupational Health and Safety Administration (OSHA) regulations, lockout/tagout (LOTO), laser safety regulations and customer site policies.
• Create Statement of Purpose (SOP), submit weekly updates and reports, and publish other requested periodic reports.
