You will need to see the dimensions of the whole thing,
to see which "chance" dimension is 1nm.

The diagram here, is too hard to read. The FINFET is on the left. The Gate All Around
device in the center. The stacked P channel and N channel on the right.

They talk here, of two wafers being bonded vertically. Which might
be how the scheme maintains a semblance of manufacturability. Imagine
an 18" (450mm" wafer, aligned at the atomic level.
