ABSTRACT:
A method of manufacturing a photodetecting device, by providing a first wafer that includes a photosensitive layer made of a semiconductor material and a second wafer that includes a circuit layer of electronic components, with one of the photosensitive layer or the circuit layer incorporating a field isolation layer; bonding the first and second wafers to form a structure comprising successively the circuit layer, the field isolation layer and the photosensitive layer; and forming electrically conductive vias to electrically connect the photosensitive layer to at least some of the electronic components of the circuit layer. Also, photodetecting devices prepared by these methods.
