The upgrade of tracking detectors for experiments at the HL-LHC and future colliders requires the development of novel radiation hard silicon sensors. We target the replacement of hybrid pixel detectors with Depleted Monolithic Active Pixel Sensors (DMAPS) that are radiation hard monolithic CMOS sensors. We designed, manufactured and tested DMAPS in the TowerJazz 180nm CMOS imaging technology with small electrodes pixel designs, that have a pixel pitch well below the current hybrid pixel detectors, and less multiple scattering due to a total silicon thickness of only 50µm. Furthermore monolithic CMOS sensors can substantially reduce detector costs. This contribution will present the development of the MALTA and MiniMALTA sensors, and the preliminary test-beam results that show the necessary steps to achieve radiation hardness at 1E15 1MeV neq/cm2.
