CMOS 65 nm ISC process. The purpose was to characterise and qualify this process and to optimise the sensor for the next generation of Monolithic Active Pixels Sensors for high-energy physics. The technology was explored in several variants which differed by: doping levels, pixel geometries and pixel pitches (10-25 µm). These variants have been tested following exposure to varying levels of irradiation up to 3 MGy and 10 16 1 MeV n eq cm −2. Here the results from prototypes that feature direct analogue output of a 4×4 pixel matrix are reported, allowing the systematic and detailed study of charge collection properties. Measurements were taken both using 55 Fe X-ray sources and in beam tests using minimum ionizing particles. The results not only demonstrate the feasibility of using this technology for particle detection but also serve as a reference for future applications and optimisations.
