Total Ionizing Dose effects on a 28 nm Hi-K metal-gate CMOS technology up to 1 Grad

This paper presents the results of an irradiation study on single transistors manufactured in a 28 nm high-k commercial CMOS technology up to 1 Grad. Both nMOSFET and pMOSFET transistors have been irradiated and electrical parameters have been measured. For nMOSFETs, the leakage current shows an increase of 2-3 orders of magnitude, while only moderate degradation for other parameters has been observed. For pMOSFETs, a more severe degradation of parameters has been measured, especially in the drain current. This work is relevant as the evaluation of a new generation of CMOS technologies to be used in future HEP experiments.
