Maintaining a pristine cleanroom necessitates careful management of electrostatic phenomena (ESD). ESD, stemming from accumulation of static charge, can detrimentally damage sensitive components used in micro-device manufacturing. Successful ESD reduction strategies include bonding all equipment, using static-dissipative substances like flooring, garments, and fixtures, and requiring humidity management to minimize charge build-up. Moreover, personnel instruction on proper ESD procedures is completely vital for ensuring environment purity.
