Description
LGAD(Low Gain Avalanche Detector) is used in the HGTD(High Granularity Time Detector) of ATLAS phase II upgrade due to its excellent time resolution and spatial granularity. In order to utilize its high granularity advantage, it is necessary to bond the detector with a front-end readout chip of the same channel size using the flip chip process. The front-end readout chip is used to collect signals, amplify, discriminate, and measure the detector signals arrival time. The LGAD electronics team at the University of Science and Technology of China has developed a prototype chip called LATIC(LGAD Amplification and Timing IC) for LGAD readout. The prototype chip has a 5x5 structure and has completed electronic testing. It has been bonded with USTC IME sensor. The structure, electronic performance testing, flip chip bonding, and preliminary test results after flip chip bonding of LATIC will be introduced.
