Embodiments provide a package substrate. The package substrate includes a substrate having a cavity hole therein, and a semiconductor device in the cavity hole. The semiconductor device has first terminal side and a second terminal side opposite to the first terminal side. The package substrate further includes a first redistribution structure on the first terminal side of the cavity substrate to electrically couple to a first pad and a second pad on the first terminal side of the semiconductor device; and a second redistribution structure on the second side of the cavity substrate to electrically couple to a third pad and fourth pad on the second terminal side of the semiconductor device.
