Question

The iPhone11 announced September 10, 2019 uses an A13 64 bit processor fabricated using 7 nm = 70 Å technology. Suppose subsequent feature size reduction tries to keep going for ten years; until 2029. What feature size would the exponential nature of “Moore’s Law” predict in 2029 and why is this going to be impossible to achieve? Hint: Lattice spacing for Si is on the order of 5.3Å. One (Angstrom) Å is 10-10 meters = 10-8cm.
