Abstract :
Previous work had indicated that there was a dependence of dynamic burnout on ion energy for specific ion types, thus, on different ranges distributions of charge. This paper presents the results of a study to determine the dependence of static MOSFET burnout on range or charge distribution in the active region of the device, for the same ion types. That is, this investigation compares these static results with dynamic measurements in order to determine why their cross section ratio is a factor of 100 to 1000. The burnout voltage thresholds were determined for four energies of iodine and bromine ions. The results show that the deposited charge for burnout is about the same value for both operating conditions, however, the dependence on operating frequency or duration of the MOSFET´s off-time introduces a reduction of cross section by a large factor
