Semiconductor fabrication and equipment manufacturing facilities contain nearly every type of hazardous energy. Hazardous energies can be found within process and support equipment, as well as the facilities. Some semiconductor tools, such as inspection equipment, may have only one or two forms of hazardous energy. Others, such as chemical vapor deposition tools, ion implantors, and chemical mechanical polishers (CMP), may contain multiple forms of hazardous energy. Knowledge and understanding of all the types of hazardous energy, in the semiconductor equipments is a must to protect yourself and others from injury.
