    Abstract: A package structure includes a lower substrate, substrate connection terminals on the lower substrate, a semiconductor package on the substrate connection terminals, the semiconductor package including a package substrate and a first encapsulant covering the package substrate, first underfills between the lower substrate and the semiconductor package, the first underfills covering corner portions of the semiconductor package, as viewed in a plan view, and covering at least one of the substrate connection terminals, and a second underfill between the lower substrate and the semiconductor package, the second underfill covering a side surface of the semiconductor package in a plan view.

    Abstract: Semiconductor packages may include a semiconductor chip including a chip pad and a lower redistribution that includes a lower redistribution insulating layer and a lower redistribution pattern. The lower redistribution insulating layer may include a top surface facing the semiconductor chip. The semiconductor packages may also include a molding layer on a side of the semiconductor chip and including a bottom surface facing the lower redistribution structure and a conductive post in the molding layer. The conductive post may include a bottom surface contacting the lower redistribution. The top surface of the lower redistribution insulating layer may be closer to a top surface of the conductive post than a top surface of the molding layer. A roughness of the top surface of the molding layer may be greater than a roughness of the top surface of the conductive post.

    Abstract: A semiconductor package includes a base chip and at least one semiconductor chip disposed on the base chip. An adhesive film is disposed between the base chip and the at least one semiconductor chip and is configured to fix the at least one semiconductor chip on the base chip. The adhesive film includes an inner film portion that overlaps the at least one semiconductor chip in a thickness direction of the base chip, and an outer film portion that does not overlap the at least one semiconductor chip in the thickness direction of the base chip. A width of the outer film portion in a direction perpendicular to a lateral edge of the at least one semiconductor chip is substantially uniform within a deviation range of 20% of an average width of the outer film portion.
