Influence of Halo Implantations on the Total Ionizing Dose Response of 28-nm pMOSFETs Irradiated to Ultrahigh Doses

Christian Enz

In this paper, the total ionizing dose (TID) response of a commercial 28-nm high-k CMOS technology at ultrahigh doses is measured and discussed. The degradation of pMOSFETs depends not only on the channel width but also on the channel length. Short-channel ...

IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019

X-ray irradiation has been extensively used in recent years as a fabrication step for nanoparticles and nanoparticle systems. A variant of this technique, continuous-flow X-ray irradiation, has recently been developed, and offers three important advantages ...

Gold nano-mesh synthesis by continuous-flow X-ray irradiation

Giorgio Margaritondo, Ying Chen

2019

The development of X-ray free-electron lasers (XFELs) has opened the possibility to investigate the ultrafast dynamics of biomacromolecules using X-ray diffraction. Whereas an increasing number of structures solved by means of serial femtosecond crystallog ...

Application of the VUV and the soft x-ray systems on JET for the study of intrinsic impurity behavior in neon seeded hybrid discharges

Jonathan Graves

This paper reports on impurity behavior in a set of hybrid discharges with Ne seeding-one of the techniques considered to reduce the power load on reactor walls. A series of experiments carried out with light gas injection on JET with the ITER-Like-Wall (I ...

Mobility Degradation of 28-nm Bulk MOSFETs Irradiated to Ultrahigh Total Ionizing Doses

Christian Enz, Farzan Jazaeri, Chunmin Zhang

Using the Y-function method, this paper experimentally investigates the effects of total ionizing dose up to 1 Grad on the channel mobility of a commercial 28-nm bulk CMOS process. ...

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 ...

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 ...
