“…Due to the small size of semiconductor devices, the amount of energy that is deposited in the elements can be so high that the semiconductor material can suffer local melting. ESD (electrostatic discharge) and its associated high electric field can cause electric breakdown of the sensitive isolation layers, especially the thin gate oxides in CMOS (complementary metal oxide semiconductor) technologies [4][5][6]. To sum up, these effects can result in latent damage or even a breakdown of the whole IC (integrated circuit), which is in some cases a relevant safety issue.…”

The electrostatic discharge (ESD) between charged metal objects produces electromagnetic (EM) fields having broad-band frequency spectra over a microwave region, which cause serious EM interference (EMI) to high-tech information equipment. For this kind of ESD fields, focussing on EM fields due to the spark discharge between metal spheres in free space, we previously demonstrated that the presence of metal spheres enhances the field level according to their sizes. For the EMI due to the above ESD, however, its mechanism is not still elucidated. This may be because even the fundamental propagation characteristics of ESD fields above a ground plane or inside a room remains unknown in conjunction with the EM coupling to equipment. In this paper, we analyzed the electric field due to an ESD event occurring in a corridor using the current dipole inside a rectangular waveguide. The distance attenuation of the field peak for the ESD occuring horizontally to the floor was examined numerically. As a result, we found that the far-field peak dopes not always decrease with increasing the distance and that there exists a region in which the field peak is enhanced with the distance. This finding was also confirmed by the spark experiment of metal spheres inside a corridor.
