The manufacturing of many products today must be carried out with consideration of cleanliness aspects, starting from computer chips, pharmaceuticals, implants to food and satellites. To meet the quality characteristic "purity," manufacturing often relies on cleanroom conditions. However, the cleanr…
1. Requirements for Particulate Purity
For integrated circuits manufactured in the semiconductor industry with feature sizes currently up to 22 nm, the high level of required particulate purity is immediately apparent. Particulate purity, meaning the absence of critical particles in the micrometer ra…

In a variety of innovative products, contamination control plays a crucial role. Despite the use of state-of-the-art cleanroom technology, critical contaminations in mass production cannot be completely ruled out. Therefore, the purity of contamination-critical products must be continuously monitore…
