Senior Research / Equipment Engineer & Lab Manager
Solar Energy Research Institute of Singapore (SERIS) / National University of Singapore (NUS)
Singapore
06.2016 - Current
- Equipment/process owner for diffusion, ion implantation, PECVD and vacuum thin-film platforms; drive stable operation, PM execution, fast recovery and CI.
- Oversee equipment installation planning and utilities hook-ups (power, CDA, N2, exhaust, cooling, safety interlocks); coordinate facilities and vendors to ensure compliant, repeatable installations.
- Develop and maintain standardized start-up/hook-up checklists, wiring/utility interface notes and troubleshooting playbooks to reduce start-up risk and improve recovery time.
- Lead troubleshooting discussions and coordinate cross-functional actions to restore equipment and contain wafer/lot risk; provide concise status updates.
- Develop and improve defense systems (interlocks, checklists, start-up/shut-down controls, parameter guard-bands) to prevent major events and reduce repeat alarms.
- Plan and execute installations/commissioning/qualification with OEMs; manage acceptance criteria, documentation and risk controls.
- Author/update OIs/SOPs and one-point lessons; train and certify users/technicians for safe, consistent tool operation.
- Support process engineering activities: recipe tuning, process window optimization, SPC-style monitoring and DOE-based troubleshooting to improve stability, yield and film performance.
- Selected achievements:
- Supported achievement of >22% implanted n-PERT cell efficiency through equipment/process stabilization and qualification support.
- Commissioned large-area thermal evaporation capability, improving tool readiness and operational stability for R&D production.
Staff Equipment Development & Deployment Engineer
SunPower Manufacturing Ltd.
Batangas, Philippines
12.2008 - 06.2016
- Led equipment deployment lifecycle: source inspection, buy-off, installation, start-up, commissioning and stabilization with OEMs and global stakeholders.
- Defined and documented standard tool hook-up requirements (utilities, exhaust, safety interlocks) and coordinated contractors/facilities for consistent installations across production lines.
- Managed project deliverables with OEMs and internal stakeholders: scope alignment, installation readiness, punch-list closure, and handover documentation to production and maintenance teams.
- Drove productivity and uptime improvements through tool modifications, recipe/process tuning, PM optimization and repeat-failure elimination.
- Coordinated tech transfer and NPI activities, aligning equipment capability to production plans and quality requirements.
- Supported process qualification runs and control plan definition during NPI/tech transfer (recipe guard-bands, SPC-style charts, yield and defect containment).
- Established best practices and documentation for sustained performance; improved troubleshooting playbooks and parts readiness with maintenance teams.
- Selected achievements:
- Led deployment of two next-generation PECVD systems for NPI; increased throughput by ~16%.
