Maintaining the pristine environment necessitates careful control of electrostatic discharge (ESD). ESD, resulting from build-up of static charge, can severely harm sensitive components used in semiconductor production. Successful ESD reduction methods require grounding all equipment, utilizing static-dissipative materials like coverings, garments, and instruments, and implementing atmospheric management to lessen voltage build-up. Moreover, personnel instruction on proper ESD procedures is absolutely vital for maintaining cleanroom purity.
