Controlling Electrostatic Discharge (ESD) in Cleanrooms: A Comprehensive Guide
Maintaining the pristine environment necessitates rigorous control of electrostatic events (ESD). ESD, stemming from generation of static charge, can seriously damage sensitive components used in micro-device fabrication. Appropriate ESD reduction methods include earthing all machinery, using static-dissipative substances like flooring, garments, and instruments, and requiring moisture management to reduce voltage build-up. Further, personnel education on proper ESD handling is necessarily vital for maintaining area purity.
