Abstract:
A method for encapsulating electronic components, including the steps of: forming, in a first surface of a semiconductor wafer, electronic components; forming, on the first surface, an interconnection stack including conductive tracks and vias separated by an insulating material; forming first and second bonding pads on the interconnection stack; thinning down the wafer, except at least on its contour; filling the thinned-down region with a first resin layer; arranging at least one first chip on the first bonding pads and forming solder bumps on the second bonding pads; depositing a second resin layer covering the first chips and partially covering the solder bumps; bonding an adhesive strip on the first resin layer; and scribing the structure into individual chips.
