Abstract (in Japanese) (See Japanese page) 
(in English) Flip chip packaging has become a general technique for mounting semiconductor ICs due to the need for smaller area. However, the exposed backside of the IC can cause EMC problems such as permanent or temporary failures due to exposure to all kinds of disturbances. Furthermore, the risk of physical attacks that exploit EMC vulnerabilities is also considered to increase. In this study, a prototype chip was fabricated to quantitatively evaluate backside voltage disturbances. The prototype chip is equipped with an on-chip monitoring circuit created with a SAR ADC, which enables measurement of silicon substrate voltages at multiple locations. Voltage disturbances were actually injected from the backside, and the voltage waveforms on the chip surface and their position dependence were confirmed.
