Abstract :
We numerically studied the neutron effects on submicron CMOS SRAM and LATCH circuits using a developed simulator which agrees well with the experimental charge collection measurements. We showed that the neutron effects have influence on SEs in advanced integrated circuits, especially for LATCH. If the Pb-Sn solder or other materials with high /spl alpha/-particle emission rates are not included, the neutrons are main SE components in advanced integrated circuits.
