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.
