> By stacking multiple nanosheet channels, the effective channel width can be maintained even within a highly compact footprint.
The fact that this level of precision can be achieved on 300mm wafers over many dozens of separate steps in separate devices is an insane achievement on its own.
> A city provides a useful analogy. When available land becomes scarce, urban planners initially reduce the spacing between buildings and use roads and open spaces more efficiently. Eventually, however, further horizontal expansion becomes impractical. At that point, the solution is to build upward. High-rise buildings create more usable space on the same piece of land by utilizing the vertical dimension.
