This thesis focuses on the characterization and simulation of 3D silicon sensors fabricated at the Centro Nacional de Microelectrónica (IMB-CNM-CSIC) within the framework of the RD50 collaboration. This work is encouraged by the upcoming upgrades for the Large Hadron Collider (LHC), the High-Luminosity LHC (HL-LHC), and the planned Future Circular Collider (FCC). These upgrades will increase the number of events per collision, which requires radiation hard silicon sensors with good time resolution to properly resolve events in time. 3D sensors are considered the best candidates for radiation harsh environments. Their short inter-electrode distance leads to a shorter travelling distance for drifting carriers, reducing the probability of being trapped by non-ionizing effects. Additionally, they yield faster signals, necessary for good time resolution performance. In this work, 3D sensors built on 200μm thick n-type wafers are studied, both before and after various levels of irradition.
