Abstract: A semiconductor package includes a first substrate, a first semiconductor chip on an upper surface of the first substrate, a first bump between the first substrate and the first semiconductor chip, a first underfill layer that fills a center portion of a space between the first substrate and the first semiconductor chip, and a first molding member that covers an upper surface and side surfaces of the first semiconductor chip, and fills a periphery portion of the space between the first substrate and the first semiconductor chip, wherein a volume occupied by the first molding member in the space between the first substrate and the first semiconductor chip is greater than a volume occupied by the first underfill layer in the space between the first substrate and the first semiconductor chip.
