Maintaining a pristine environment necessitates rigorous management of electrostatic discharge (ESD). ESD, stemming from generation of static electricity, can severely harm sensitive components used in micro-device fabrication. Appropriate ESD reduction approaches require bonding each apparatus, employing antistatic items like flooring, garments, and instruments, and enforcing moisture regulation to lessen voltage build-up. Further, personnel instruction on proper ESD procedures is necessarily critical for maintaining cleanroom quality.
