Abstract:
A method of manufacturing a semiconductor device comprising the steps of:providing a semiconductor wafer having a main surface, the semiconductor wafer including a plurality of semiconductor chip regions each of which has a protruding electrode formed on the main surface of the semiconductor wafer, a plurality of scribe lines on the main surface surrounding each of the semiconductor chip regions;providing a substrate having a chip mounting surface and a back surface, the substrate including a plurality of main body portions each of which corresponds to one of the semiconductor chip regions and a plurality of cut lines each of which corresponds to one of the scribe lines, each of the main body portions having an inner pad formed on the chip mounting surface and a connecting pad formed on the back surface, the inner pad corresponding to the protruding electrode, each of the cut lines having a resin injecting hole extending from the chip mounting surface to the back surface;mounting the substrate with the chip mounting surface on the main surface of the semiconductor wafer so that the protruding electrodes are connected to the inner pads, respectively, and a space between the chip mounting surface of the substrate and the main surface of the semiconductor wafer is created;injecting a resin into the space between the chip mounting surface and the main surface through resin injecting holes;curing the injected resin; andcutting the substrate, the cured resin and the semiconductor wafer along the cut lines so as to provide a plurality of semiconductor devices each of which includes one of the semiconductor chip regions of the semiconductor wafer, the main body portion of the substrate are corresponding thereto, and the cured resin therebetween.
