Abstract:
1. A method for encapsulating, comprising the steps of: (a) forming, inside and on top of a first surface of a semiconductor wafer, electronic components; (b) forming, on the first surface of the wafer, an interconnection stack comprising conductive tracks and vias separated by an insulating material; (c) forming first and second bonding pads on the interconnection stack; (d) thinning down a majority of a volume of the semiconductor wafer, except at a periphery of the wafer; (e) filling the thinned-down region with a first resin layer; (f) installing at least one first chip on the first bonding pads and forming solder bumps on the second bonding pads; (g) depositing a second resin layer covering the first chips and partially covering the solder bumps; (h) bonding an adhesive strip on the first resin layer; and (i) scribing the structure into individual chips.
