A fab cleanroom is thousands of times cleaner than a hospital operating theatre — and the biggest contamination source in it is you. Learn how air, suits and discipline keep billion-transistor chips alive.
Before anyone enters a fab, they gown up in a strict sequence — from the particles' point of view, not fashion's. Click the six steps in the correct order.
Every movement you make sheds skin flakes, fibres and droplets — invisible to you, catastrophic to a chip whose features are 500× smaller than a dust grain. Pick a behaviour and watch the counter.
WHY IT MATTERS · an ISO Class 1 fab cleanroom allows fewer than 10 particles (≥0.1µm) per cubic metre of air. A typical city street corner has tens of millions.
