CMOS monolithic pixel sensors based on the column-drain architecture for the HL-LHC upgrade

Depleted Monolithic Active Pixel Sensors (DMAPS) constitute a promising low cost alternative for the outer layers of the ATLAS experiment Inner Tracker (ITk). Realizations in modern, high resistivity CMOS technologies enhance their radiation tolerance by achieving substantial depletion of the sensing volume. Two DMAPS prototypes that use the same "column-drain" readout architecture and are based on different sensor implementation concepts named LF-Monopix and TJ-Monopix have been developed for the High Luminosity upgrade of the Large Hardon Collider (HL-LHC). LF- Monopix was fabricated in the LFoundry 150 nm technology and features pixel size of 50x250 μm2 and large collection electrode opted for high radiation tolerance. Detection efficiency up to 99\% has been measured after irradiation to 1⋅1015 neq/cm2. TJ-Monopix is a large scale (1x2 cm2) prototype featuring pixels of 36x40 μm2 size. It was fabricated in a novel TowerJazz 180 nm modified process that enables full depletion of the sensitive layer, while employing a small collection electrode that is less sensitive to crosstalk. The resulting small sensor capacitance (<=3 fF) is exploited by a compact, low power front end optimized to meet the 25ns timing requirement. Measurement results demonstrate the sensor performance in terms of Equivalent Noise Charge (ENC) ≈11e−, threshold ≈300 e−, threshold dispersion ≈30 e− and total power consumption lower than 120 mW/cm2.
