Abstract

Embodiments of the inventive aspect include a printed circuit board and a semiconductor package using the same. The semiconductor package includes a substrate having one or more connection pads, semiconductor chips mounted on the substrate, an underfill layer filling a region between the semiconductor chips and the substrate, and solder bumps electrically connecting the connection pads and the semiconductor chips in the underfill layer. The substrate includes void preventing patterns protruding on a top surface of the substrate under the underfill layer.
