Fully-depleted CMOS sensors represent a significant step forward in radiation detection, combining the advantages of monolithic active pixel sensors with the enhanced signal collection efficiency of depleted bulk materials. The ARCADIA Collaboration established a technology platform for the development and production of deep sub-micron fully-depleted CMOS monolithic sensors with excellent collection efficiency, advancing the semiconductor detector technology with IP cores, ASICs and back-end dedicated acquisition systems. The sensor technology was demonstrated on system-ready full chip monolithic active pixel sensors with high rate capability and very low power for the detection of charged particles and photons. Innovative CMOS monolithicLGADs featuring a shallow gain layer and implementing a low-gain avalanche diode were developed for time-of-flight detectors, while other prototype ASICs implement multi-threshold photon-counting architectures for X-ray imaging. The implementation of fully-depleted monolithic strip sensors with embedded electronics and low power density makes the proposed approach † Thomas Corradino is now with Fondazione Bruno Kessler (FBK),
