Understanding 3D Die Stacking Technology

What is 3D Die Stacking?

3D die stacking involves vertically stacking multiple semiconductor dies (chips) in a single package. This technique allows for increased integration density, reduced footprint, and improved electrical performance. By placing dies on top of one another rather than side by side, manufacturers can save space and enhance connectivity among components.

How 3D Die Stacking Works

The process involves several key steps:

1. Wafer Fabrication: Individual dies are fabricated on silicon wafers using traditional semiconductor manufacturing techniques.
2. Die Preparation: The dies are then prepared for stacking, including thinning and polishing to ensure uniformity.
3. Stacking and Bonding: The dies are stacked and bonded using advanced techniques like through-silicon vias (TSVs) or micro-bump bonding, which allow for high-speed interconnects between layers.
4. Encapsulation: The stacked assembly is encapsulated to protect it from environmental factors and mechanical stress.
