We seek a Research Fellow to advance low-temperature Cu/dielectric hybrid bonding for fine-pitch, high-density interconnects by developing and validating a new flow with reliable dielectric sealing under ≤200 °C.

The role integrates materials selection, wafer-level process development, and reliability demonstration to deliver a manufacturable 3D-integration solution that supports NTU’s leadership in industry-relevant advanced packaging research.

Key Responsibilities

• Develop and run a Cu–Cu hybrid bonding flow for fine-pitch 3D integration.
• Optimize process windows (pressure/temperature/anneal/surface activation) to minimize contact resistance and voids; maintain cleanroom/tool best practices.
• Characterize materials and interfaces using optical/profilometry, SEM/TEM, surface chemistry, and electrical IV; translate data into process improvements.
• Validate reliability and scalability via thermal cycling/HTS/electrical stress on test vehicles; build prototype stacks (e.g., interposer/test-chip) to evidence manufacturability.
• Report and collaborate: produce clear technical reports/presentations, coordinate with partners, and maintain rigorous documentation, version control, and safety compliance.

Job Requirements

• PhD in Materials/ Microelectronics/ EEE/ or related.
• Hands-on semiconductor process development in cleanroom (Cu interconnect/wafer or hybrid bonding; litho/etch/CMP/plasma/anneal).
• Characterization: optical/profilometry, SEM/TEM, XPS/AFM, electrical probing; DoE/statistics (Python/Matlab a plus).
• Strong documentation, safety discipline, and clear communication in English.
• Process integration & optimization; root-cause/failure analysis.
• Reliability mindset (design/interpret thermal & electrical stress tests).
• Collaboration with tool vendors/industry partners; concise reporting; ownership.
