Description
In this contribution we present RSD2, the second production of Resistive AC-Coupled Silicon Detectors (RSD), a new frontier in 4D particle tracking through Silicon detectors with internal gain and 100% fill-factor. RSD are n-in-p LGAD-based detectors characterized by three key-elements: (i) a continuous multiplication implant, without any segmentation, (ii) a resistive n-cathode and (iii) a dielectric coupling layer deposited on top. Thanks to the internal gain and the capacitive radout, RSD allow to reach almost the same timing performances of traditional LGADs, with high performances in space reconstruction. Starting from the very good results of the previous run, RSD1, we will introduce some important details about the new technological and physical parameters implemented in RSD2, designed at INFN Torino and manufactured in 2021 by Fondazione Bruno Kessler (FBK) in Trento. To this aim, TCAD simulations, layout design and a full electrical characterizations will be provided.
