Abstract: A pixel includes a first electrode layer on an exposed surface of an interconnection structure and in contact with a conductive element of the interconnection structure. An insulating layer extends over the first electrode layer and includes opening crossing through the insulating layer to the first electrode layer. A second electrode layer is on top of and in contact with the first electrode layer and the insulating layer in the opening. A film configured to convert photons into electron-hole pairs is on the insulating layer, the second electrode layer and filling the opening. A third electrode layer covers the film.
