Own assigned backend test equipment (e.g. ATE systems, handlers, loaders, probers, unloaders, tape and reel) and ensure high equipment availability, reliability, and performance in line with production demand.
Plan, execute, and continuously improve preventive maintenance (PM) programs and drive effective corrective actions to minimize downtime and recurring failures.
Develop, qualify, and optimize test processes, recipes, and parameters to achieve target yield, throughput, and quality.
Perform yield monitoring, trend analysis, and failure analysis to identify root causes of test failures, escapes, or retest issues, and implement sustainable corrective actions.
Support test program releases, changes, and re-runs, ensuring alignment with SEMI standards, quality requirements, and engineering change controls.
Lead and participate in continuous improvement initiatives (OEE improvement, cycle time reduction, cost per unit reduction, retest reduction) using structured problem-solving methods.
Support capacity planning, line balancing, and production ramp-up activities, including new product introduction (NPI) and volume expansion.
Create, maintain, and control engineering documents such as SOPs, WI, PM checklists, FMEA, and control plans in compliance with internal and customer requirements.
Work closely with Manufacturing, Quality, Test Development, Planning, Facilities, and Vendors to resolve issues and drive operational excellence.
Analyze equipment and process data (downtime, yield, SPC, alarms) and prepare technical reports and dashboards for management and stakeholders.
Support tool installation, qualification, buy-off, and transfer of new test platforms or technologies into production.
Train technicians, operators, and junior engineers on equipment operation, troubleshooting, and process controls to ensure consistent execution.
