Towards a new generation of Monolithic Active Pixel Sensors
/ Chauhan, Ankur (DESY) ; Viera, Manuel Del Rio (DESY ; Bonn U.) ; Eckstein, Doris (DESY) ; Feindt, Finn (DESY) ; Gregor, Ingrid-Maria (DESY) ; Hansen, Karsten (DESY) ; Huth, Lennart (DESY) ; Mendes, Larissa (DESY ; U. Campinas) ; Mulyanto, Budi (DESY) ; Rastorguev, Daniil (DESY ; Wuppertal U.) et al.
A new generation of Monolithic Active Pixel Sensors (MAPS), produced in a 65 nm CMOS imaging process, promises higher densities of on-chip circuits and, for a given pixel size, more sophisticated in-pixel logic compared to larger feature size processes. MAPS are a cost-effective alternative to hybrid pixel sensors since flip-chip bonding is not required. [...]

Developing a Monolithic Silicon Sensor in a 65nm CMOS Imaging Technology for Future Lepton Collider Vertex Detectors
/ Simancas, Adriana (DESY, Zeuthen ; Bonn U.) ; Braach, Justus (CERN ; Hamburg U.) ; Buschmann, Eric (CERN) ; Chauhan, Ankur (DESY, Zeuthen) ; Dannheim, Dominik (CERN) ; Viera, Manuel Del Rio (DESY, Zeuthen ; Bonn U.) ; Dort, Katharina (CERN ; Giessen U.) ; Eckstein, Doris (DESY, Zeuthen) ; Feindt, Finn (DESY, Zeuthen) ; Gregor, Ingrid-Maria (DESY, Zeuthen) et al.
Monolithic CMOS sensors in a 65 nm imaging technology are being investigated by the CERN EP Strategic R&D; Programme on Technologies for Future Experiments for an application in particle physics. The appeal of monolithic detectors lies in the fact that both sensor volume and readout electronics are integrated in the same silicon wafer, providing a reduction in production effort, costs and scattering material.
