Reply to comment by richiehustle in ELI5: Why computer chips nanometers progress is gradual? Why can not the technology bump up to the lowest nm possible immediately since the concept and mechanisms of it is already known and studied by richiehustle

We know theory and practice don't precisely align in semiconductors. They live on the finnicky edge of quantum physics

Semiconductor devices books will have two charts next to each other. One telling you what the equation says the values should be and one showing you what the actual measured values tend to be. They can be off by >20% at times because exactly where in the silicon crystal that phosphorous atom landed matters a lot
