I was reading the July issue and saw the data on The Skin We Shed, Pg. 4. 1 have always suspected this but it is nice to have data. It isn't clear if this is particles shed from the skin inside the bunny suit or if the particles have come through the bunny suit? It really doesn't matter, we know the particles will come through the bunny suit eventually.

This brings up the idea of making the bunny suit of a plastic that has been given a permanent electrostatic charge. Such a fabric would not only hold the skin particles, it would collect stray particles floating about in the air.

Before you can say “the charged fabric would endanger ESD on the wafers,” we tried it on the most sensitive open devices that a manufacturer in Phoenix could provide – there was no damage. The manufacturer was hot to buy garments made of the charged material, it is available, but the bunny suit makers had no interest.

Perhaps this letter will change things, I have lots of data if some one wants to see it.
