Serious troubles may occur in electromagnetic equipments due to electrostatic discharge (ESD). The number of the damaging incidents are significantly increasing with the increased use of integrated semiconductor elements with loer operation pwoer. In order to examine the phenomena theoretically, this paper anlyzes properties of the transient electromagnetic fields rdiated by ESD. A new model is presented using the Rompe-weizel formula for the spark resistance. The numerical results of ESD fields are compared with the experimental data that were given by wilson-Ma.

To establish measuring method for minimum ignition energy of explosive powders caused by electrostatic discharge, A measuring method(Hartman) using a very small quantity of pine tree testing powder was proposed, and the influence of discharge current limiting resistance connected in series into a capacitive discharge circuit on ignition energies of explosive powders was investigated. As a result the minimum ignition energy was 42.25mJ when discharge current limiting resistance 300 $k\Omega$.

반도체 소자에 정전기 방전으로 인한 소자내의 온도 상승을 알기 위해 열전달 방정식으로부터 열모델을 유도하였다. 그리고 열파괴 문턱전류를 얻고 시간에 따른 온도 변화를 열모델로부터 해석하였다. 여기서 유도한 열모델은 Wunsch-Bell모델에 지수 항을 추가한 형태이다. 이 모델의 유효성을 증명하기 위해 실험결과와 비교한 결과 매우 잘 일치하였으므로 이 열모델의 함수는 입력보호회로의 반도체소자를 설계하는데 매우 유용하다.

전압 인가식 제전방식이 반도체나 디스플레이 산업에는 가장 많이 사용되고 있지만, 방전에 의한 주변 미세 먼지의 흡착 및 전극핀의 오염으로 불량 발생의 원인을 제공하므로, 주기적인 관리 비용이 발생하게 된다. 전극핀의 오염 문제는 코로나 방전으로 인하여, 주변 공기의 미세한 입자를 축적함으로 생성된다. Fuzz ball의 생성은 전극핀의 마모를 촉진 시키고, 또한 정전기 제거 장치의 성능을 저하시킨다. 오염물 제거 방법은 수동 브러쉬 및 자동 브러쉬를 이용하여 기계적인 세척 방법이 효과적이지만, 추가적인 기계부품이나 사용자의 관리를 요구한다. 일부의 경우에는 이미터에 축척된 오염물이 웨이퍼나 제품에 전이될 수도 있다. 이러한 문제를 해결하기 위해, 제전기의 외부로 돌출되는 전극핀을 없애고, 이온탱크 내부에 위치한 텡스텐 전극선을 이용하여 주위 기체 분자를 직접 이온화할 수 있는 청정 환경에 적합한 정전기 제거 장치를 개발하였다. 한국기계연구원에서 시험인증한 결과, 오염 입자는 평균 $0.7572particles/ft^3$이고, 제전 시간은 2초 이하 이며, 잔류 전위는 7.6V로 만족할 만한 결과를 얻었다.

Ionizer is used for improving manufacturing process and reducing inferior goods in the clean room. As a general rule, neutralization of the electrostatic charge is most important to make TFT-LCD, PDP and OLED. Pulse AC-static eliminator with output voltage of about 10.5kV has been used these days as neutralization device. But this device has a problem with lower performance which was caused by particles-adhesion on the electrode when it has been used for a long time. So we studied to solve the problem with lower performance using high Frequency(72kHz) static eliminator which was produced by Piezo transformer device, and compared Pulse-AC type with Piezo-electronic device such as decay time and ion balance for 10 weeks periods. As a result of this study, we found that Piezo transformer device has been maintained normal condition for 10 weeks. Also, we made the rule by this study, normally Piezo transformer device has to clean the electrode during every 11th weeks.

Despite the increasing importance of manufacturing and application R&D for ultrapure deionized water and electrolyzed ion water, various and systematic studies have not been conducted until now. In this study, the electrostatic discharge (ESD) behavior of electrolyzed ion water using a proton exchange membrane(PEM) was evaluated according to the type, flow rate, and bubble of electrolyzed ion water. In addition, by observing that Oxidation Reduction Potential (ORP) value returns to the unique value of electrolyzed ion water after electrostatic discharge, the possibility of two types of ions participating in electrostatic discharge ((H₂O)_n⁺ (assumed)) and ions for maintaining the characteristics of electrolyzed water could be inferred. In order to confirm the chemical structure and characteristics of the cations, in-depth research related to water molecular orbital energy or band gap should be followed.

To establish testing method for ignition energy of explosive powders caused by electrostatic discharge, one testing method using a very small quantity of tested powders ( Frima ) was proposed, and the influence of discharge - limiting resistance connected in series into a capacitive discharge circuit on ignition energies of explosive powders was investigated using, as tested powders. As a result the minimum ignition energy was 9 mJ when discharge-limiting resistance was 300 k$\Omega$. The reason for the dependence of ignition energy on discharge-limiting resistance was thought to the difference in the type of electrostatic discharge, such as arc or glow discharge, from the observation of discharging wave forms.

A modern electronic system located at a certain distance form the discharge may respond with unexpected sensitivity ot that phenomenon, even if the phenomenon is so slight as to have been ignored in the port. It has been found that electromagnetic wave energy is emitted as a results of this electrostatic discharge between metallic objects. In order to theoretically examine the peculiar phenomenon, we propose an analytical approach to model the indirect ESD effect. A soruce model is given here using the spark resistence presented by rompe-weizel. A model experiment for indirect eSD is also conducted to express ESD detection rate by the statistical estimation. We verify that the statistical estimations agree the theoretical curve resulted from the rompe-weisel resistence.
