Why is Bunny Suit necessary at Intel?

Answer 1

I don't know much about what they're called, but you do need to wear special suits in order to enter a clean room that is involved in manufacturing ICs and processors as even the introduction of a tiny piece of contaminant can ruin the whole thing.

Answer 2

Because the 'bunny suit' stops dust and skin cells from the workers contaminating the computer circuitry. It's the same at any computer manufacturers.
