Maintaining a pristine cleanroom necessitates rigorous regulation of electrostatic discharge (ESD). ESD, caused from build-up of static charge, can detrimentally damage sensitive devices used in micro-device fabrication. Appropriate ESD prevention approaches include bonding each equipment, using antistatic items like coverings, attire, and tooling, and requiring moisture control to lessen potential build-up. Moreover, personnel training on proper ESD procedures is completely essential for maintaining environment purity.
