Characterization and Modeling of Gigarad-TID-Induced Drain Leakage Current of 28-nm Bulk MOSFETs

Christian Enz, Farzan Jazaeri, Chunmin Zhang, Federico Faccio

This paper characterizes and models the effects of total ionizing dose (TID) up to 1 Grad(SiO2) on the drain leakage current of nMOSFETs fabricated with a commercial 28-nm bulk CMOS process. Experimental comparisons among individual nMOSFETs of various siz ...

Assessment of nanoparticles’ safety: corrected absorbance-based toxicity test

Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin

We developed a method to correct absorbance-based toxicity tests to remove the influence of the deposited dose of nano-particles. As a model of absorbance-based toxicity tests, we chose the frequently used MTS test. The corrected cell viabilities obtained ...

Total Ionizing Dose Effects on Analog Performance of 28 nm Bulk MOSFETs

Christian Enz, Claudio Bruschini, Farzan Jazaeri, Chunmin Zhang, Alessandro Pezzotta

This paper uses the simplified charge-based EKV MOSFET model for studying the effects of total ionizing dose (TID) on analog parameters and figures-of-merit (FoMs) of 28nm bulk MOSFETs. These effects are demonstrated to be fully captured by the five key pa ...

Characterization of GigaRad Total Ionizing Dose and Annealing Effects on 28-nm Bulk MOSFETs

Christian Enz, Claudio Bruschini, Farzan Jazaeri, Chunmin Zhang, Alessandro Pezzotta, Federico Faccio

This paper investigates the radiation tolerance of 28-nm bulk n and pMOSFETs up to 1 Grad of total ionizing dose (TID). The radiation effects on this commercial 28-nm bulk CMOS process demonstrate a strong geometry dependence as a result of the complex int ...

On the origin of primary 1/2 a(0) and a(0) loops in irradiated Fe(Cr) alloys

Robin Schäublin, Anna Prokhodtseva

The radiation-induced primary dislocation loops in thin foils of ultra-high purity Fe and Fe(Cr) model alloys were investigated using ion irradiation in situ in a TEM. In the '111 mechanism' the induced nanometric loops of type a(0) stem from mutual ...
