Abstract:
1. A method of making a semiconductor device, comprising: providing a substrate having a ground plane disposed over a surface of or within the substrate; mounting a plurality of semiconductor die over the surface of the substrate above the ground plane, the ground plane being continuous and extending from under a first semiconductor die of the plurality of semiconductor die to under a second semiconductor die of the plurality of semiconductor die; forming a shielding layer over the plurality of semiconductor die; depositing an encapsulant over the substrate and plurality of semiconductor die after forming the shielding layer; creating a first channel between the plurality of semiconductor die through the shielding layer and the encapsulant and further through the substrate at least to a depth to cut through the ground plane; depositing a conductive material in the first channel; and cutting a second channel through the conductive material in the first channel and completely through the substrate with a width less than a width of the first channel to singulate the plurality of semiconductor die leaving a portion of the conductive material in the first channel, the portion of the conductive material, shielding layer, and ground plane completely enclosing each semiconductor die and the conductive material in the first channel providing an electrical connection between the shielding layer and ground plane.
