4 matrix of 256*256 pixel. Self-bias No radiation Tolerant pixel. Noise optimized. High precision tracking pixel This sensors have been designed and fabricated for this application using AMS 0.35 OPTO process. Single sensor consists of 512x512 pixel array with a pitch of 10 µm, providing an active area of 5x5 mm2 fabricated using standard (14 µm thick epitaxy) and experimental (20 µm epitaxy)
