A 4D-tracker demonstrator based on the Timespot1, a CMOS 28-nm ASIC

The Timespot1 ASIC was developed using 28-nm CMOS technology within the TimeSPOT/IGNITE collaborations and aimed to bridge the gap between available fast-timing ASICs and those required for high-luminosity applications. We present results of the performance of the Timespot1 hybrid, where 3D trench silicon and 3D columnar diamond sensors have been bump-bonded to the Timespot1 ASIC
