High-tech industries have long been plagued by an unseen foe. From semiconductors to medical devices, manufacturers are forced to accept high product rejection rates due to particle contamination or critical defects. Oftentimes, contamination issues and product damage in these industries can be traced back to uncontrolled static electricity. When static is allowed to build-up, it becomes a double threat to a cleanroom, increasing the chances of ESA-induced contamination and electrostatic discharge (ESD) damage.
ESA Contamination in Cleanrooms
Electrostatic attraction (ESA) is the phenomenon that causes dust to stick to the glass screen of an old vacuum tube television. When particles become statically charged by friction or contact with another material, they adhere to surfaces that have the opposite charge. While this may seem harmless in the example of the TV monitor, the semiconductor industry works on
