What is 3D packaging?

3D packaging in the explanations

• 3D packaging has the advantage of shorter wiring, but because heat-generating chips are stacked, heat tends to build up and is hard to remove from the inner chips.

  Which is especially likely to be a challenge in 3D packagin…

• 3D packaging stacks chips vertically and connects them with TSVs or hybrid bonding.

  Which correctly describes the difference between 2.5D and 3…

• It allows chips to be stacked with many connections over shorter distances than wire bonding, so it is used in 3D packaging and HBM.

  Which correctly describes a TSV (through-silicon via)?
