MATRICE DE PHOTODETECTEURS, A PIXELS ISOLES ET GRILLE DE STOCKAGE, HYBRIDEE SUR UN CIRCUIT DE LECTURE

摘要

A matrix of photosensors (10) destined to be hybridised on a reading circuit (30) is made from a plate of semiconductor material (11) presenting a receiving surface for light to be detected and an opposing hybridisation surface. The plate is divided into pixels (12), each made up of a photosensor, separated by a means of separation formed in the plate and incorporating a storage grid for the photosensors. Each photosensor has a connection stud (18) allowing the hybridisation of the matrix of photosensors onto the reading circuit. The means of separation comprise some walls incorporating an electrical conducting partition (13) sandwiched between electrical insulating partitions (14, 15).
