You scrubbed the air to parts-per-trillion. Your cleanroom pressure cascades are perfect. Your operators are moving flawlessly. Then, a freight train rolls by five kilometers away (or under you in a subway ) —and your multi-million-dollar extreme ultraviolet (EUV) lithography run is ruined. We spend so much time looking up at our HEPA filters that we often forget to look down at our foundation. In my latest article, I break down why contamination isn't just physical particles or trace gases—it is kinetic and electromagnetic energy. If you manage a sub-nanometer critical cleanroom, an electron microscope facility, precision metrology, advanced optics cleanroom or a quantum lab, this is why your floor might be betraying your airflow.
