Maintaining a pristine cleanroom necessitates strict management of electrostatic events (ESD). ESD, resulting from build-up of static potential, can seriously damage sensitive components used in micro-device fabrication. Appropriate ESD reduction strategies require bonding every machinery, employing static-dissipative substances like flooring, attire, and fixtures, and requiring humidity management to reduce voltage build-up. Further, personnel training on proper ESD techniques is absolutely vital for maintaining area quality.
