/ Solans Sánchez, C (CERN) ; Allport, P (Birmingham U.) ; Asensi Tortajada, I (CERN) ; Berlea, D V (Oslo U.) ; Bortoletto, D (Oxford U.) ; Dachs, F (CERN) ; Dao, V (CERN) ; Denizli, H (Abant Izzet Baysal U.) ; Dobrijevic, D (CERN ; Zagreb U.) ; Dyndal, M (CERN) et al.
Depleted Monolithic Active Pixel Sensors are of highest interest at the HL-LHC and beyond for the replacement of the Pixel trackers in the outermost layers of experiments where the requirement on total area and cost effectiveness is much bigger. They aim to provide high granularity and low material budget over large surfaces with ease of integration. [...]

MALTA3: Concepts for a new radiation tolerant sensor in the TowerJazz 180 nm technology
/ Dobrijević, Dominik (CERN ; U. Zagreb (main)) ; Allport, Phil (Birmingham U.) ; Asensi, Ignacio (CERN) ; Berlea, Dumitru-Vlad (DESY, Zeuthen) ; Bortoletto, Daniela (U. Oxford (main)) ; Buttar, Craig (Glasgow U.) ; Dachs, Florian (CERN) ; Dao, Valerio (CERN) ; Denizli, Haluk (Abant Izzet Baysal U.) ; Flores, Leyre (CERN) et al.
The upgrade of the MALTA DMAPS designed in Tower 180 nm CMOS Imaging process will implement the numerous modifications, as well as front-end changes in order to boost the charge collection efficiency after the targeted fluence of 1x10$^{15}$ 1 MeV$n_{eq}$/cm$^{2}$. The effectiveness of these changes have been demonstrated in recent measurements with a small-scale Mini-MALTA demonstrator chip. [...]

The MALTA family of depleted monolithic pixel sensors produced in TowerJazz 180 nm CMOS technology target radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have resulted in radiation hardness >10$^{15}$ 1 MeV n$_{eq}$/cm$^{2}$ and time resolution below 2 ns, with uniform charge collection and efficiency across the pixel of size 36.4 × 36.4 µm$^{2}$ with small collection electrode.

To achieve the physics goals of future colliders, it is necessary to develop novel, radiation-hard silicon sensors for their tracking detectors. We target the replacement of hybrid pixel detectors with Depleted Monolithic Active Pixel Sensors (DMAPS) that are radiation-hard, monolithic CMOS sensors. [...]

The planned MALTA3 DMAPS designed in the standard TowerJazz 180 nm imaging process will implement the numerous process modifications, as well as front-end changes in order to boost the charge collection efficiency after the targeted fluence of 1 × 10$^{15}$ 1 MeV n$_{eq}$/cm$^{2}$. The effectiveness of these changes have been demonstrated with recent measurements of the full size MALTA2 chip. [...]

The last couple of years have seen the development of Depleted Monolithic Active Pixel Sensors (DMAPS) fabricated in TowerJazz 180nm with a process modification to increase the radiation tolerance. While many of MAPS developments focus on low radiation environment, we have taken the development to high radiation environment like pp-experiments at High Luminosity LHC [...]
