Monolithic silicon sensors developed with High-Voltage CMOS (HV-CMOS) processes have become highly attractive for charged particle tracking. Compared with the standard CMOS sensors, HV-CMOS sensors can provide larger and deeper depletion regions that lead to larger signals and faster charge collection. [...]

Active silicon detectors built on p-type substrate are a promising technological solution for large area silicon trackers such as those at the High Luminosity LHC, but the radiation hardness of this novel approach has to be evaluated. Active n-in-p strip detector prototypes CHESS2 for ATLAS with different substrate resistivities in the range of 20–1000 Ωcm were irradiated with neutrons and protons up to a fluence of 2×10$^{15} $n$_{eq}$ cm$^{-2}$ and 3.6×10$^{15} $n$_{eq}$ cm$^{-2}$ .

ATLAS has formed strip CMOS project to study the use of CMOS MAPS devices as silicon strip sensors for the Phase-II Strip Tracker Upgrade. This choice of sensors promises several advantages over the conventional baseline design, such as better resolution, less material in the tracking volume, and faster construction speed. [...]

Study of built-in amplifier performance on HV-CMOS sensor for the ATLAS phase-II strip tracker upgrade
/ Liang, Z (UC, Santa Cruz, Inst. Part. Phys. ; Beijing, Inst. High Energy Phys.) ; Affolder, A (Liverpool U.) ; Arndt, K (Oxford U.) ; Bates, R (Glasgow U.) ; Benoit, M (Geneva U.) ; Di Bello, F (Geneva U.) ; Blue, A (Glasgow U.) ; Bortoletto, D (Oxford U.) ; Buckland, M (Liverpool U. ; CERN) ; Buttar, C (Glasgow U.) et al.
This paper focuses on the performance of analog readout electronics (built-in amplifier) integrated on the high-voltage (HV) CMOS silicon sensor chip, as well as its radiation hardness. Since the total collected charge from minimum ionizing particle (MIP) for the CMOS sensor is 10 times lower than for a conventional planar sensor, it is crucial to integrate a low noise built-in amplifier on the sensor chip to improve the signal to noise ratio of the system.

Radiation hardness of two CMOS prototypes for the ATLAS HL-LHC upgrade project

The LHC luminosity upgrade, known as the High Luminosity LHC (HL-LHC), will require the replacement of the existing silicon strip tracker and the transistion radiation tracker. Although a baseline design for this tracker exists the ATLAS collaboration and other non-ATLAS groups are exploring the feasibility of using CMOS Monolithic Active Pixel Sensors (MAPS) which would be arranged in a strip-like fashion and would take advantage of the service and support structure already being developed for the upgrade.
