A method forms an air gap metal tip structure for (ESD) protection. The method forms an air chamber, from an upper substrate and a lower substate disposed below the upper substrate, within which a first metal tip and a second metal tip are disposed. The first and second metal tips are disposed along at least one horizontal axis parallel to the upper and lower substrates. The chamber includes a portion between points of the metal tips, such that oxygen trapped in the chamber is converted into ozone responsive to an arc between the metal tips to dissipate the arc, and the ozone is decomposed back into the oxygen responsive to an arc absence between the metal tips to maintain the ESD protection for subsequent arcs. An under fill level is disposed between the lower and upper substrates, and above one or more layers having the first and second metal tips.

Disclosed is a static eliminator having an offset voltage reducing structure capable of improving antistatic performance for a charged body by reducing an ion offset voltage. The present static eliminator comprises a static eliminator body having an air passage through which high-pressure air is supplied, a plurality of discharge structures installed at the lower end of the static eliminator body to supply the high-pressure air passing through the air passage, and generating positive/negative ions by discharging using the applied high voltage, and an offset voltage reduction unit having a plurality of openings formed to allow the positive/negative ions and high-pressure air to pass therethrough, and installed to cover at least some of the plurality of discharge structures.

The object of the present invention is to suitably control a charging state of a human body all the time. A charging amount detection device 13 is worn by a human body and measures the surface potential of the human body. A static electricity control device 12 is worn by a human body and generates and discharges ions to the human body and thereby controls the static electricity on the human body. A mobile terminal 11 sets a control pattern of the static electricity on the human body that is suitable for a condition such as temperature and humidity for the static electricity control device 12 via short-range wireless communication. The static electricity control device 12 uses the set control pattern to perform feedback control of the static electricity on the human body by using the surface potential of the human body measured by the charging amount detection device 13.
