Stanford Seminar - Low-Cost 3D Chip Stacking with ThruChip Wireless Connections

Stanford University via YouTube

Overview

The current Stacking methods challenges are its high costs. This seminar from Thruchip discusses the advantages of using Wireless approach for stacking 3D chips.

Wireless stacking allows chips to be stacked at a lower cost, and lower power and provides a higher bandwidth.
