ATLASPix3 – A reticle sized HV-CMOS Detector for Construction of Multi-Sensor Modules — •Rudolf Schimassek1, Felix Ehrler1, Mridula Prathapan1, Alena Weber1,2, Winnie Wong3, Hui Zhang1, and Ivan Perić11Karlsruher Institut für Technologie — 2Universität Heidelberg — 3Université de Genève

Monolithic High-Voltage CMOS (HV-CMOS) detectors are a sensor type planned to be used for tracking in several particle physics experiments. HV-CMOS Sensors are especially well suited for applications with strict constraints on mass and spatial resolution. In addition, low power and radiation hardness, along with good time resolution are possible. Furthermore, the usage of standard CMOS processes makes the detectors highly available and cheap.

To overcome the mask size limit of HV-CMOS processes, the ATLASPix3 detector is designed to be used in multi-chip modules. It is a 2×2.1 cm2 three side buttable pixel sensor, designed for the environment of layer 4 of the ATLAS inner tracker upgrade for High-Luminosity LHC. A single data input and a single data output are sufficient to control and read out the detector using protocols that are RD53 compatible. The detector was produced on a high resistivity substrate and the first production shows a good yield. In this contribution, measurements of the detector features and performances will be presented.
