Job Summary
GlobalFoundries Fab8 is seeking a highly skilled and motivated R&D TSV engineer to become part of our Quantum Advanced Packaging team. The primary responsibility of this position is to own development and integration of cryogenic, superconducting TSV technologies enabling high-density vertical interconnects for scalable quantum packaging from concept through manufacturing.
Essential Responsibilities
Lead development of through-silicon via (TSV) processes for cryogenic and superconducting applications.
Define TSV architectures including:
Superconducting liners (e.g., Nb, Al-based)
Dielectric isolation schemes
Via geometries (diameter, depth, pitch)
Ensure TSV designs are optimized for:
Low-loss electrical/RF signal transport
Cryogenic thermal and mechanical stability
Own end-to-end TSV integration flows across:
Via etch, liner deposition, dielectric, and metallization
Wafer thinning, reveal, and backside processing
Integration into 2.5D/3D packaging stacks
Drive process integration planning to enable prototyping and qualification across programs.
Develop TSV solutions for superconducting interposers and 3D integration platforms
Support integration with:
Bump/interconnect layers
Redistribution routing layers (RDL)
Assembly and bonding flows
Ensure TSVs enable high-density vertical interconnects for quantum system scaling.
Enable prototype builds and development lots, ensuring smooth execution through fab and assembly flows.
Support transition from R&D to pilot to manufacturable flows.
Collaborate with device/test teams to ensure TSVs meet:
Optimize interface integrity between via liner, dielectric, and substrate.
Define requirements for TSV-specific process tools:
Deep silicon etch (DRIE)
Conformal deposition (PVD/CVD/ALD)
Wafer thinning and reveal
Collaborate with equipment vendors and suppliers to develop new capabilities.
Support qualification of new tooling and materials.
Interface across:
Interconnect (bump / RDL) teams
Assembly and integration engineers
Device / qubit / system engineers
Ensure co-optimization of TSVs with full packaging stack.
Drive development of next-generation TSV scaling, including:
Smaller diameters and higher aspect ratios
Alignment with micro-bump pitch scaling
Contribute to cryogenic 3DHI roadmap and APPC capability build-out.
Evaluate novel via concepts (e.g., superconducting-lined, partially filled, or air-gap vias).
Generate:
TSV integration flows and specifications
Design rules and process documentation
Provide technical updates, reports, and data-driven insights.
Contribute to IP, publications, and conference outputs.
Other Responsibilities
Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs.
Take part in hiring of other Advanced Packaging team members in Singapore.
Mentor and guide new hires to assume their roles and responsibilities.
Other duties as assigned by manager.
Required Qualifications
