3D-sequentially integrated transistors show strong layer-to-layer coupling of total-ionizing-dose responses due to radiation-induced trapped charges in the intermediate dielectric region between upper and lower device layers.

DC and low frequency noise measurements on 16 nm Si bulk FinFETs irradiated to 1 Grad(SiO2) show charge buildup in STI. The TID sensitivity depends on channel length, and fin and finger number.

Employing GexSe100-x glasses to monitor temperature using the phase change effect is reported. Materials selection, device structure and a prototype of temperature sensor performance are analysed. Heavy ion irradiation by Xe ions has been studied.

A simplified approach to estimating radiation-induced Si-SiO2 interface trap densities, based on steady-state populations of relevant mobile species, is presented. Calculations are consistent with known trends in dose, dose rate, hydrogen content and temperature.
