Description
4D-tracking is a highly relevant topic in the development of future tracking detectors for high-energy physics experiments. Among the most promising sensor technologies for tracking in 4 dimensions are Resistive Silicon Detectors (RSD), based on Low Gain Avalanche Diode (LGAD) technology, that aim to achieve a timing resolution of approximately 30 ps and a spatial resolution of the order of a few percent of the pixel pitch. The effectiveness of resistive read-out for space reconstruction has been demonstrated with AC-coupled RSDs. Building on this, INFN and FBK proposed an improved version of this technology featuring DC-coupling (DC-RSD) between read-out channels and the resistive layer.
This contribution presents an overview of the first production of DC-RSDs fabricated by FBK within the framework of 4DSHARE project. The DC-RSD design aims to confine signal sharing within individual pixel through Trench Isolation (TI) technology. The batch was extensively characterized at wafer level and single devices have been characterized with laser TCT system and with real particles in beam tests at DESY. This contribution will present the key features of the DC-RSD design and the most recent results obtained on their spatial and temporal resolutions.
