Description
Monolithic Active Pixel Sensor prototypes developed in the TowerJazz 180 nm CMOS imaging process have been designed in the context of the ATLAS upgrade Phase-II at the High-Luminosity LHC. These are characterized by a small collection electrode design (3 um), and a small pixel size (36.4 um), on high resistivity substrates and large voltage bias. The latest prototype of this technology, so-called Mini-MALTA, addresses the pixel in-efficiencies observed in previous designs to meet the radiation hardness requirements. This contribution will highlight recent results from characterization of the sensors in particle beam tests, where full efficiency up to 1E15 neq/cm2 and 70 Mrad is observed.
