Hybrid pixel detectors are a type of [[ionizing radiation]] detector consisting of an array of diodes based on [[semiconductor detector|semiconductor technology]] and their associated electronics. The term “hybrid” stems from the fact that the two main elements from which these devices are built, the semiconductor sensor and the readout chip (also known as application-specific integrated circuit or ASIC), are manufactured independently and later electrically coupled by means of a bump-bonding process. Ionizing particles are detected as they produce electron-hole pairs through their interaction with the sensor element, usually made of doped [[silicon]] or [[cadmium telluride]]. The readout ASIC is segmented into pixels containing the necessary electronics to amplify and measure the electrical signals induced by the incoming particles in the sensor layer. |

Hybrid pixel detectors are a type of ionizing radiation detector consisting of an array of diodes based on semiconductor technology and their associated electronics. The term “hybrid” stems from the fact that the two main elements from which these devices are built, the semiconductor sensor and the readout chip (also known as application-specific integrated circuit or ASIC), are manufactured independently and later electrically coupled by means of a bump-bonding process. Ionizing particles are detected as they produce electron-hole pairs through their interaction with the sensor element, usually made of doped silicon or cadmium telluride. The readout ASIC is segmented into pixels containing the necessary electronics to amplify and measure the electrical signals induced by the incoming particles in the sensor layer.
Hybrid pixel detectors made to operate in single-photon mode are known as Hybrid Photon Counting Detectors (HPCDs). These detectors are designed to count the number of hits within a certain time interval. They have become a standard in most synchrotron light sources and X-ray detection applications.Brönnimann, C.; Trüb, P. (2018).
