Maintaining the pristine area necessitates careful control of electrostatic discharge (ESD). ESD, caused from accumulation of static electricity, can severely harm sensitive parts used in semiconductor manufacturing. Effective ESD reduction approaches include grounding every apparatus, employing static-dissipative materials like surfaces, clothing, and fixtures, and enforcing atmospheric management to lessen potential build-up. Further, personnel education on proper ESD techniques is necessarily essential for guaranteeing environment quality.
