Static electricity is an electrical energy that remains on the surface of an object and is the result of the imbalance of positive and negative charges in a localized range. It is formed by the conversion of electrons or ions. Electrostatic phenomena are a general term for electrical phenomena that are generated during the generation and disappearance of electric charges. Such as frictional electrification, human body electrification and so on. With the development of science and technology, electrostatic phenomena have been widely used in the fields of electrostatic spraying, electrostatic spinning, electrostatic sorting, and electrostatic imaging. On the other hand, the generation of static electricity can cause significant harm and loss in many fields. For example, in the first Apollo manned spacecraft, three astronauts were killed as a result of electrostatic discharges; accidents caused by electrostatic discharge (ESD) during the manufacture of gunpowder occurred. In the electronics industry, as the integration becomes higher and higher, the inner insulating layer of the integrated circuit becomes thinner and thinner, and the width and spacing of the interconnecting wires become smaller and smaller. For example, the typical thickness of the insulating layer of the CMOS device is about 0.1 μm. The corresponding breakdown voltage is 80-100V; the insulation layer of the VMOS device is thinner and the breakdown voltage is 30V. The electrostatic voltage generated in the manufacture of electronic products and in transportation and storage processes far exceeds the breakdown voltage of MOS devices. The Kunshan carrier tape often causes hard breakdown or soft breakdown (partial damage of the device). It invalidates or seriously affects the reliability of the product. In order to control and eliminate ESD, developed countries such as the United States, Western Europe, and Japan have established national, military, and corporate standards or regulations. From the design, manufacture, purchase, storage, inspection, warehousing, assembly, commissioning, packaging and transportation of semi-finished and finished products, there are corresponding regulations on the manufacture and use of static protective equipment. Institutional requirements. China has also established military and enterprise standards with reference to international standards. For example, there are standards such as the Ministry of Space, the Ministry of Electrical and Mechanical Services, and the Ministry of Petroleum
