MoTiC: Prototype of a Depleted Monolithic Pixel Detector with Timing

MoTiC is a prototype of a Depleted Monolithic Active Pixel Sensor capable of time measurements. The chip is produced in a modified LFoundry 110 nm process with a pixel pitch of 50 μm × 50 μm and three active thicknesses of 48, 100 and 200 μm. The chip comprises a number of different amplifier and sensor designs for evaluation. MoTiC was characterized with particle beams before irradiation. The characterization results presented in this paper demonstrate that a hit detection efficiency in excess of 99.8 %, a spatial resolution better than 5 μm and a coarse timing resolution better than 1.2 ns are achieved.
