Developments on CMOS with LF, AMS and TJ technology

HV-CMOS sensors represent a solid candidate detector for the future of high-energy physics experiments. The LFoundry (LF) 150 nm, the Austria Micro System (AMS) aH18 180 nm and the TowerJazz (TJ) 180 nm HV-CMOS process has been under investigation for pixel detectors at the High Luminosity Large Hadron Collider (HL-LHC). The pixel response of an LF prototype in terms of gain and times of signal, an efficiency estimation of an AMS one along with measurements on fall and rise times, ToT and time walk and for TJ results from a test beam at CERN showed that this technology can qualify for the design of the outer pixel layers of the ATLAS Inner Tracker (ITk)
