enormous spaces with laminar flow. So cool! most relaxing place in the world, wonderful background white noise for getting work done. Most cleanrooms are now class 10 (meaning 10 half micron sized particles per square meter) compared to a class 1,000 operating room. The wafers are all sealed in the 'clearnoom within the cleanroom' spaces of tools and FOUPS. I have heard of fabs having problems fro msources as strange as nearby farms and earthquakes half way around the world. The filtering (ultra-HEPA filters) will absolutely clear up your alergies almost over night.
