Maintaining the pristine environment necessitates rigorous regulation of electrostatic discharge (ESD). ESD, stemming from build-up of static potential, can seriously damage sensitive parts used in micro-device fabrication. Appropriate ESD mitigation methods include bonding each apparatus, utilizing ESD-safe substances like surfaces, garments, and instruments, and requiring atmospheric control to lessen charge generation. Additionally, personnel training on proper ESD procedures is completely vital for maintaining area purity.
