Maintaining the pristine area necessitates rigorous control of electrostatic discharge (ESD). ESD, resulting from generation of static potential, can detrimentally affect sensitive devices used in semiconductor manufacturing. Successful ESD mitigation methods require bonding all machinery, using ESD-safe materials like surfaces, clothing, and tooling, and enforcing humidity management to lessen charge generation. Moreover, personnel instruction on proper ESD handling is necessarily essential for guaranteeing cleanroom quality.
