Each of the sub-packages further includes a signal redistributed layer pattern extending to electrically connect the signal pad to a signal connection part and a power redistributed layer pattern to electrically connect the power pad to the first and second power through vias. An upper sub-package of the sub-packages is rotated relative to a lower sub-package, and the rotated upper sub-package is stacked on a lower sub-package of the sub-packages.
