The Mu3e experiment is searching for the charged lepton flavour violating decay $ \mu^+\rightarrow e^+ e^- e^+ $, aiming for an ultimate sensitivity of one in $10^{16}$ decays. In an environment of up to $10^9$ muon decays per second the detector needs to provide precise vertex, time and momentum information to suppress background. The detector consists of cylindrical layers of $ 50\ \mu\text{m} $ thin High Voltage Monolithic Active Pixel Sensors(HV-MAPS) placed in a $1\ T$ magnetic field, which allow a precise vertex and momentum reconstruction. Additional layers of fast scintillating fibre and tile detectors are providing sub-nanosecond time resolution.
The MuPix8 chip is the first large scale prototype, proving the scalability of the technology. It was produced in the AMS aH18 $180\, \text{nm}$ HV-CMOS process. It consists of three sub-matrices, each providing an untriggered datastream with more than $10\ \text{MHits}/s$. The latest results from laboratory and testbeam characterisiation will be presented, showing an excellent performance with efficiencies $>99.6$% and a time resolution better than $10\ \text{ns}$ achieved with time walk correction. Further, first results from the new prototype MuPix9 will be highlighted and the R&D roadmap towards the final Mu3e chip will be shown.
