Investigation of non-idealities of pulsing circuitry in the ALICE ITS3 MOSS monolithic sensor
/ Emiliani, S (CERN) ; Aglieri Rinella, G (CERN) ; Lemoine, C (CERN ; Strasbourg, IPHC) ; Piro, F (CERN) ; Ripamonti, G (CERN) ; Snoeys, W (CERN) ; Suljic, M (CERN) ; Terlizzi, L (Turin U.)
The MOSS wafer-scale monolithic sensor, designed for the vertex detector (ITS3) of the ALICE experiment, features a pixel input capacitance of ∼ 5 fF. Such a small input capacitance is needed to reach a satisfactory SNR with a low-power analog front-end (36 nW/pixel). [...]

CMOS Monolithic Active Pixel Sensors: challenges and perspectives
/ Snoeys, Walter (speaker) (CERN)
CMOS cameras revolutionized the visible imaging world, and now move into other fields. CMOS Monolithic Active Pixel Sensors (CMOS MAPS) have been successfully used in the STAR experiment and are now taking data in the 10 m2 Inner Tracker System (ITS2) of the ALICE experiment at CERN. CMOS MAPS in high energy physics (HEP) continue to be the object of intense research and development, for instance in EP R&D WP1.2 and DRDs, and for future ALICE and LHCb upgrades, and detectors at FCC. CMOS MAPS for HEP face very different requirements, but their development greatly benefits from the progress of CMOS imagers for visible light, the integration offered by stitching and wafer stacking, as well as trends in mainstream CMOS.
3D wafer stacking and stitching are now well established for CMOS sensors for visible light, and stacking is also now intensely pursued in mainstream CMOS. [...]

“LF-Monopix2” and “TJ-Monopix2” are the second generation of “Monopix” Depleted Monolithic Active Pixel Sensor prototypes fabricated in 150 nm and 180 nm CMOS processes, respectively. Both devices implement a fully functional column-drain read-out architecture at a reticle-size scale, but differ on the concept used for pixel design. [...]

Characterisation of analogue MAPS produced in the 65 nm TPSCo process
/ ALICE Collaboration
Within the context of the ALICE ITS3 collaboration, a set of MAPS small-scale test structures were developed using the 65 nm TPSCo CMOS imaging process with the upgrade of the ALICE inner tracking system as its primary focus. One such sensor, the Circuit Exploratoire 65 nm (CE-65), and its evolution the CE-65v2, were developed to explore charge collection properties for varying configurations including collection layer process (standard, blanket, modified with gap), pixel pitch (15, 18, \SI{22.5}{\micro\meter}), and pixel geometry (square vs hexagonal/staggered).
