Abstract
Monolithic Active Pixel Sensors (MAPS) benefit from a cost-effective implementation as they make use of commercial CMOS process, avoiding expensive interconnections to additional front-end ASIC. The ARCADIA collaboration has developed Fully-Depleted MAPS exploiting backside bias voltage to fully deplete the sensor, thereby enhancing charge collection efficiency and timing performance. Recent advancements have explored the introduction of a gain layer in MAPS to design a first monolithic LGAD prototype targeting 20 ps time resolution. The signal multiplication results in a higher signal-to-noise ratio and improved time resolution. This work illustrates preliminary characterization results of monolithic LGAD prototypes with an additional gain layer, based on a 110 nm CMOS technology developed in collaboration with LFoundry for the third run of the ARCADIA project.
