Maintaining the pristine area necessitates strict regulation of electrostatic events (ESD). ESD, resulting from generation of static potential, can seriously harm sensitive components used in semiconductor production. Successful ESD reduction methods require grounding each apparatus, employing ESD-safe substances like surfaces, attire, and fixtures, and implementing moisture control to reduce voltage generation. Moreover, personnel education on proper ESD procedures is absolutely essential for guaranteeing cleanroom integrity.
