Abstract

Disclosed are semiconductor packages and/or methods of fabricating the same. The semiconductor package comprises a package substrate, a first semiconductor chip mounted on the package substrate, a second semiconductor chip mounted on a top surface of the first semiconductor chip, and a first under-fill layer that fills a space between the package substrate and the first semiconductor chip. The package substrate includes a cavity in the package substrate, and a first vent hole that extends from a top surface of the package substrate and is in fluid communication with the cavity. The first under-fill layer extends along the first vent hole to fill the cavity.
