• Define routing, metallization, and integration schemes optimized for:
  • Low-loss RF/microwave signal propagation
  • Minimal thermal leakage
  • Cryogenic reliability
• Own end-to-end integration of interposer and interconnect flows across:
  • Wafer-level processes (RDL, TSV/TOV, via formation)
  • Die-level integration (bump, bonding, assembly interfaces)
• Drive process integration planning to enable new capabilities and prototyping across programs.
• Architect and integrate multi-die quantum packaging solutions, including:
  • Qubit die + control electronics
  • Superconducting interposers
• Support chiplet-style and system-level integration for scalable quantum systems.
• Translate system-level requirements into interconnect density, pitch, and routing specifications.
• Enable early-stage prototyping lots, ensuring smooth execution through fab and assembly lines.

  • Interposer fabrication
  • Advanced 3DHI integration
• Interface across:
  • Device / qubit teams
  • Assembly, bump, and TSV integration teams
  • Reliability and modeling teams
• Collaborate with OSATs, suppliers, and research partners to co-develop interconnect technologies.
• Drive next-generation interconnect scaling (pitch, density, materials) aligned with quantum system scaling needs
• Contribute to advanced packaging roadmap (APPC / cryo 3DHI).
• Identify and evaluate emerging interconnect technologies and integration schemes.
• Generate:
  • Integration flow documentation
  • Process specs and design rules
• Provide technical reports and progress updates to internal and external stakeholders.
• Contribute to IP, publications, and conference outputs.

Other Responsibilities
