Maintaining a pristine environment necessitates strict control of electrostatic events (ESD). ESD, stemming from generation of static electricity, can seriously damage sensitive parts used in micro-device manufacturing. Appropriate ESD prevention methods involve grounding every apparatus, using static-dissipative substances like coverings, garments, and tooling, and implementing moisture management to reduce potential build-up. Moreover, personnel training on proper ESD handling is completely critical for maintaining environment purity.
