Abstract
Disclosed is a semiconductor package comprising an interposer substrate having first and second surfaces opposite each other and including a wiring layer adjacent to the first surface, a semiconductor chip on the first surface of the interposer substrate, a passivation layer on the first surface of the interposer substrate and covering the semiconductor chip, and redistribution patterns in the passivation layer and connected to the semiconductor chip. The semiconductor chip has third and fourth surfaces opposite to each other. The third surface of the semiconductor chip faces the first surface of the interposer substrate. The redistribution patterns are connected to the fourth surface of the semiconductor chip. The semiconductor chip includes chip pads adjacent to the third surface and chip through electrodes connected to the chip pads. Each of the chip pads is directly bonded to a corresponding one of wiring patterns in the wiring layer.
