Chapter 03 of 5
The Nanometer Mirage
Why chip 'sizes' are marketing math and how quantum tunneling breaks physics.
- The Benchmark
Vanishing Scales
Intel’s 4004 chip had features 10,000 nanometers wide. Modern chips are approaching the width of a single DNA strand.
- Industry Secret
The Marketing Math
A '5nm' chip doesn't have any features that are 5 nanometers. The number is now a density label, not a physical measurement.
- Structural Shift
The Gatekeeper
For decades, the planar transistor was a flat sandwich. As size shrank, the 'gate' lost control over the flow of electrons.
