/ Berlea, D V (DESY, Zeuthen ; Humboldt U., Berlin) ; Allport, P (Birmingham U.) ; Asensi Tortajada, I (CERN) ; Behera, P (Indian Inst. Tech., Madras) ; Bortoletto, D (Oxford U.) ; Buttar, C (Glasgow U.) ; Dachs, F (CERN) ; Dao, V (CERN) ; Dash, G (Indian Inst. Tech., Madras) ; Dobrijevic, D (CERN ; Boskovic Inst., Zagreb) et al.
MALTA2 is a depleted monolithic active pixel sensor (DMAPS) developed in the Tower 180 nm CMOS imaging process. Monolithic CMOS sensors offer advantages over current hybrid imaging sensors both in terms of increased tracking performance due to lower material budget but also in terms of ease of integration and construction costs due to the monolithic design.

The MALTA family of Depleted Monolithic Active Pixel Sensors (DMAPS) is produced using Tower 180 nm CMOS technology, specifically targeting radiation-hard applications in the HL-LHC and beyond. Several process modifications have resulted in radiation hardness up to ${3 \times 10^{15}~1 ~\text{MeV}~\text{n}_{\text{eq}} /\text{cm}^2}$ and time resolution below 2 ns, with uniform charge collection efficiency across the chip formed of $512 \times 224$ pixels with a size of $36.4 \times 36.4~\mu\text{m}^2$.

MALTA2 is the latest full-scale prototype of the MALTA family of Depleted Monolithic Active Pixel Sensors (DMAPS) produced in Tower Semiconductor 180 nm CMOS technology. In order to comply with the requirements of High Energy Physics (HEP) experiments, various process modifications and front-end changes have been implemented to achieve low power consumption, reduce Random Telegraph Signal (RTS) noise, and optimise the charge collection geometry.

MALTA is a depleted monolithic active pixel sensor (DMAPS) developed in the Tower Semiconductor 180-nm CMOS imaging process. Monolithic CMOS sensors offer advantages over current hybrid imaging sensors in terms of both increased tracking performance due to lower material budget and ease of integration and construction costs due to the integration of read-out and active sensor into one ASIC.

The MALTA silicon pixel detector combines a depleted monolithic active pixel sensor (DMAPS) with a fully asynchronous front-end and readout. It features a high granularity pixel matrix with a 36.4 μm symmetric pixel pitch, low power consumption of <1 μW/pixel and low material budget with detector thicknesses as little as 50 μm. [...]

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. [...]
