A generalized EKV charge-based MOSFET model including oxide and interface traps

This paper presents a generalized EKV charge-based MOSFET model that includes the effects of trapped charges
in the oxide bulk and at the silicon/oxide interface. It is shown that in the presence of oxide- and interface trapped charges, the mobile charge density can still be linearized but with respect to both the surface potential and the channel voltage. [...]

This paper investigates the effects of total ionizing dose up to 1 Grad on 28-nm bulk MOSFETs under different bias conditions during irradiation. The aim is to assess the potential use of this commercial bulk CMOS technology in the future high-luminosity Large Hadron Collider at CERN that will require highly improved radiation-tolerant tracking systems..

Characterization and Modeling of Gigarad-TID-Induced Drain Leakage Current of 28-nm Bulk MOSFETs
/ Zhang, Chun-Min (Ecole Polytechnique, Lausanne) ; Jazaeri, Farzan (Ecole Polytechnique, Lausanne) ; Borghello, Giulio (CERN ; U. Udine (main)) ; Faccio, Federico (CERN) ; Mattiazzo, Serena (Padua U. ; INFN, Padua) ; Baschirotto, Andrea (Milan Bicocca U. ; INFN, Milan Bicocca) ; Enz, Christian (Ecole Polytechnique, Lausanne)
This paper characterizes and models the effects of total ionizing dose (TID) up to 1 Grad(SiO$_2$) on the drain leakage current of nMOSFETs fabricated with a commercial 28-nm bulk CMOS process. Experimental comparisons among individual nMOSFETs of various sizes provide insight into the TID-induced lateral parasitic devices, which contribute the most to the significant increase up to four orders of magnitude in the drain leakage current.

GigaRad total ionizing dose and post-irradiation effects on 28 nm bulk MOSFETs
/ Zhang, C M (Ecole Polytechnique, Lausanne) ; Jazaeri, F (Ecole Polytechnique, Lausanne) ; Pezzotta, A (Ecole Polytechnique, Lausanne) ; Bruschini, C (Ecole Polytechnique, Lausanne) ; Borghello, G (CERN ; U. Udine (main)) ; Faccio, F (CERN) ; Mattiazzo, S (U. Padua (main)) ; Baschirotto, A (Milan Bicocca U.) ; Enz, C (Ecole Polytechnique, Lausanne)
The DC performance of both $n$- and $p$MOSFETs fabricated in a commercial-grade 28 nm bulk CMOS process has been studied up to 1 Grad of total ionizing dose and at post-irradiation annealing. The aim is to assess the potential use of such an advanced CMOS technology in the forthcoming upgrade of the Large Hadron Collider at CERN. [...]

Total ionizing dose effects on analog performance of 28 nm bulk MOSFETs

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 parameters of the simplified EKV model. [...]

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

Padua (main)) ; Baschirotto, Andrea (Milan Bicocca U.) ; Enz, Christian (Ecole Polytechnique, Lausanne)
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 interplay of oxide and interface charge trapping relevant to the gate-related dielectrics and the shallow trench isolation.

The Large Hadron Collider (LHC) running at CERN will soon be upgraded to increase its luminosity giving rise to radiations reaching the level of GigaRad Total Ionizing Dose (TID). This paper investigates the impact of such high radiation on transistors fabricated in a commercial 28 nm bulk CMOS process with the perspective of using it for the future silicon-based detectors.
