Maintaining the pristine cleanroom necessitates careful control of electrostatic events (ESD). ESD, stemming from generation of static potential, can detrimentally affect sensitive parts used in micro-device production. Effective ESD mitigation approaches require grounding each machinery, employing static-dissipative items like coverings, attire, and tooling, and implementing atmospheric regulation to lessen charge build-up. Further, personnel education on proper ESD techniques is completely vital for maintaining area quality.
