Description
The Future Circular Collider e+e- (FCC-ee) is proposed as CERN's next-generation collider experiment for precision measurements of the Higgs and W/Z bosons and the top quark. Its physics program demands vertex detectors with excellent spatial resolution and a low material budget, favoring Monolithic Active Pixel Sensors (MAPS) for their thin, low-power design. We present R&D on High-Voltage MAPS (HV-MAPS) targeting the requirements of FCC-ee's Tera-Z program for spatial precision and radiation tolerance. Using TCAD process and device simulations, we studied a 25 micron thick sensor capable of being operated at a high-bias. The HV-MAPS sensor design was optimized through parameter scans of the design parameters, and the performance of the optimized design was quantified. These results provide early input for HV-MAPS sensor designs for future prototyping studies and will help steer R&D efforts to meet the requirements of the FCC-ee.
