Which mechanism limits etching precision on semiconductor wafers?

💡 Explanation

Quantum tunneling allows electrons to penetrate the potential barrier at the edges, rather than stopping abruptly; therefore the etching isn't perfectly sharp because electrons propagate beyond the defined feature edges blurring results.
