Description
In this contribution we present an update about the development of Monolithic Active Pixel Sensors (MAPS) at INFN in the framework of the ARCADIA project. Thanks to the first two engineering runs, manufactured in 2020 and 2021 with a 110 nm CMOS process, the device concept has been well assessed and tested, both through extensive laboratory characterizations and the comparison between experimental measurements and numerical simulations. In view of timing applications, a multiplication layer has been added to the design of our third run, delivered in early 2023. Here we present the first electrical and dynamic characterization campaigns performed on the passive test structures, which proved that the sensors (i) can be depleted and (ii) properly operate in the charge multiplication regime. Finally, also a few key aspects of the sensor optimization in perspective of the incoming productions will be considered through the discussion of combined TCAD-Montecarlo numerical analyses.
