Abstract:
1. A method for manufacturing an electronic module, the method comprising: arranging a plurality of semiconductor chips on a carrier laterally adjacent along rows and columns in form of a matrix, each semiconductor chip comprising a vertical electrical device, a first main face and a second main face opposite the first main face, the first main face comprising at least one electrical contact and the second main face comprising at least one electrical contact, wherein only the at least one electrical contact on the second main face has a contact pad disposed thereon and the at least one electrical contact on the first main face is devoid of a contact pad; forming a material layer over each semiconductor chip and in intermediate spaces between the semiconductor chips; removing the carrier from the second main faces of the semiconductor chips; forming a redistribution layer on the second main faces of the semiconductor chips; forming a second electrical contact layer on the redistribution layer; removing the material layer above the semiconductor chips thereby exposing the first main faces of the semiconductor chips; forming a contact pad for electrical connection on each of the at least one electrical contacts on the first main faces of the semiconductor chips, wherein before forming the contact pads an ion implantation is performed on each of the semiconductor chips as a final step of fabricating the vertical electrical device within the semiconductor chips; and forming a first continuous electrical contact layer on the contact pads of the first main faces of the semiconductor chips so that the first continuous electrical contact layer is electrically connected with each one of the electrical contacts of the semiconductor chips, wherein the first continuous electrical contact layer covers the entire matrix of semiconductor chips.
