Maintaining a pristine area necessitates rigorous management of electrostatic discharge (ESD). ESD, resulting from build-up of static potential, can seriously harm sensitive components used in semiconductor fabrication. Successful ESD mitigation strategies require earthing all machinery, employing static-dissipative items like surfaces, attire, and instruments, and requiring humidity control to minimize potential build-up. Additionally, personnel training on proper ESD techniques is completely critical for maintaining area integrity.
