TWEPP 2021 Topical Workshop on Electronics for Particle Physics

Abstract

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 up to 2e15 n/cm2 and time resolution below 2 ns, with uniform charge collection efficiency across the Pixel of size 36.4 x 36.4 um2 with a 3 um2 electrode size. This contribution will present the results from new cascoded front-end flavour that further reduces the RTS noise and improves the threshold reach, and the comparison of samples produced on high-resistivity epitaxial silicon with Czochralski substrates
