Measurement And Tridimensional Simulation Of Silicon Pixel Detector Capacitance

Abstract

We report on a study of the capacitance of silicon pixel detectors to be used as tracking devices for high energy physics experiments. The pixel capacitance matrix plays an important role in system design issues, such as preamplifier matching and cross-talk among pixels. Test results on 100 x 100 pm2 pixels are compared with data obtained from a massively parallel tridimensional simulation code which is necessary to account for the intrinsically 3D nature of the pixel structure.
