Abstract

A semiconductor package includes a substrate, a redistribution circuit layer, and a protective layer. The redistribution circuit layer is over the substrate and includes a plurality of functional pads electrically connected to the substrate, and a dummy pad pattern electrically disconnected from the plurality of functional pads, wherein the dummy pad pattern includes a plurality of pad portions connected to one another. The protective layer is disposed over the redistribution circuit layer and comprising a plurality of first openings spaced apart from one another and respectively revealing the plurality of pad portions.
