Abstract
A two-dimensional photonic radiation detector based on a technique of hybridizing a detection chip onto a read chip through a micro-balls network making the electrical and mechanical inter-connection between two chips, the detection chip being composed of a two-dimensional structure of ixj pixels, an active layer (,) being epitaxed onto a substrate (,), each elementary photosensitive component consisting of an N/P or P/N diode formed in the active layer (,), the contact point on the N or P area being made at each pixel, the contact point on the other P or N area being common to all diodes, in which the detector includes a wide gap optically and electrically transparent intermediate layer (,) located between the active layer (,) and the substrate (,).
