Outline of Final Research Achievements

To conduct further verification of Rompe-Weizel’s and Toepler’s spark resistance formulae for micro-gap ESDs, a newly developed measurement setup for spark currents, which allows to simply estimating the spark current and the corresponding spark voltage from the measured discharge currents, was used to measure the characteristics of spark discharges at charge voltages of 500 V and 4000 V. As a result, we found that the spark currents nearly equal to the measured discharge currents. It was also found that at a charge voltage of 500 V, the Toepler’s formula is applicable to predicting the spark process, while at a charge voltage of 4000 V, the Rompe-Weizel’s formula can well explain the spark process quantitatively. This result supports our previous study, despite the fact that the spark lengths estimated from both the spark resistance formulae with their commonly used spark constants do not agree with the measured results.
