Abstract:
1. A manufacturing method of electronic device having at least one module, comprising: providing a substrate; disposing at least one component on the substrate; forming a molding to encapsulate the component and a portion of the substrate; forming at least one first hole on said molding to expose a ground pad of said component; forming at least one second hole on said molding to expose a power pad of the component; subsequently, forming a first conductive layer to conformingly cover the module molding and be electrically connected to the ground pad through the at least one first hole and the power pad through the at least one second hole; patterning said first conductive layer to separate the first conductive layer into a ground region and a power region, wherein the ground region is electrically connected to the ground pad and the power region is electrically connected to the power pad, and wherein a majority of an upper surface of the module molding is covered by the ground region and the power region; forming a passivation layer to cover said first conductive layer, wherein the passivation layer has an opening to expose a portion of the ground region; and forming a second conductive layer to cover the passivation layer and be electrically connected to the ground region through the opening.
