“…Since the NIEL is unknown in the literature, the DDD cannot be estimated neither. However, as a heavy ion (six protons and six neutrons), due to its large cross section as well as its charge and mass, we expect to have a huge DDD resulting from both nuclear and coulombic interactions [15]. Characterizations have been performed one week after irradiation.…”

We propose to identify the displacement damage defects induced by proton and carbon irradiations in a com mercial off-the-shelf pinned photodiode (PPD) 8T-CMOS image sensors (CISs) dedicated to space application operating in global shutter mode. This paper aims to provide a better understanding of defects creation in a specific space image sensor. Therefore, it leads to comparable results to those we could find during the mission. The study focuses on bulk defects located in the PPD depleted region which represents the main dark current contribution in PPD CIS. Four sensors have been irradiated with carbon ions and protons at different energies and fl uencies. Using both the dark current spectroscopy and the random telegraph si gn al (RTS) analysis, we investigate defects behavior for different isochronal a,mealing temperatures. By combi1ùng these results, we make the connection between two complementary phenomena and bring out the prevalence of divacancies-based defects in terin of dark current contribution.

-A first principles study of the defects generated by displacement cascades in silicon is performed. This work is particularly focused on two defect configurations; the di-vacancy and the triinterstitial, both identified in previous Molecular Dynamics (MD) and kinetic Activation Relaxation Technique (k-ART) simulations [1,2]. By combining structural, energy and migration properties evaluated within the framework of the standard Density Functional Theory (DFT) and electronic properties calculated within the G 0 W 0 approximation, a reconstruction of the corresponding thermallyactivated electrical signal generated by each defect is obtained. Their contribution to Dark Current (DC) and Dark Current Random Telegraph Signal (DC-RTS) measured in image sensors is then discussed.
