Three Dimensional Integrated Circuits (3D IC)

Ferromagnetic Through Silicon Vias (FTSVs) in 3D ICs enable AC power distribution instead of DC. Enhance heat management and facilitate intra-IC communication. Vias and interconnects in the technology domain of 3D integrated circuits (3D ICs) are getting significant direction in IC research. However, power distribution, heat management, and intra-IC communication issues in state-of-the-art interconnects severely limit their development and integration in 3D ICs. PI, using its IP Foundry, equipped with deep tech expertise and cutting-edge research, invented Ferromagnetic Through Silicon Vias (FTSVs).

This invention utilizes the unique magnetic properties of ferromagnetic materials to enhance communication and thermal conductivity through ferromagnetic through silicon vias.

Compared to traditional through silicon vias, FTSVs enable:

  • Improved power transfer efficiency by using AC power transfer instead of DC
  • Improved heat dissipation
  • Enhanced inter-chiplet communication capabilities

By using FTSVs, IC manufacturers can significantly enhance product performance and competitiveness, driving the widespread adoption of 3D integrated circuits.
