Wafer Sort Process Engineer

Job Description:

1. Optimize and maintain wafer sort test processes to meet OSAT production targets for output, quality, and turnaround time.
2. Manage wafer sort process flow within OSAT operations, ensuring smooth handover between wafer sort and downstream.
3. Analyse wafer test data and yield trends to troubleshoot process issues, lead root cause investigations, and implement corrective actions to satisfy customer requirements.
4. Collaborate with product engineering, test engineering, quality, and equipment teams to support new product introductions (NPI) and volume ramp-ups.
5. Drive continuous process improvement initiatives focused on throughput increase.
6. Support customer audits and ensure wafer sort processes comply with OSAT quality standards (e.g., ISO, IATF) and customer-specific protocols.
7. Maintain process documentation, SOPs, work instructions, and training materials relevant to wafer sort operations.

Requirements:

1. Bachelor's degree in Electrical Engineering, Electronics Engineering, Materials Science, or related field.
2. Minimum 3 years of experience in wafer sort or semiconductor test process engineering.
3. Strong knowledge of wafer probe test equipment and wafer test methodologies.
4. Good understanding of semiconductor manufacturing processes, yield analysis, and statistical process control (SPC).
5. Strong analytical and problem-solving skills with high attention to detail.
6. Ability to manage multiple projects in a fast-paced manufacturing environment.
7. Knowledge of cleanroom protocols and safety regulations.
