F04900 - SEMI F49 - Guide for Semiconductor Factory Systems Voltage Sag Immunity StdDcs-Withdrawn org in October 2005A guide defining a systems approach to power conditioning is needed for semiconductor and flat panel display (FPD) facilities. Semiconductor and FPD factories require high levels of power quality due to the sensitivity of equipment and process controls. Semiconductor and FPD processing equipment are especially vulnerable to voltage sags. The facility electrical system distributes power to process equipment, support equipment, and facility
