Abstract:
A semiconductor device comprising:a first semiconductor element; a redistribution substrate having a first surface and a second surface opposite to the first surface, the first semiconductor element being mounted on the first surface; a plurality of electrode pads arranged on the first surface of the redistribution substrate, the electrode pads being electrically connected to the first semiconductor element; a plurality of protruding electrodes provided on the respective electrode pads; and a plurality of through holes extending from the second surface of the redistribution substrate to respective electrode pads, wherein the first semiconductor element is encapsulated by a seal material, and a distance between a top of each of the protruding electrodes and the first surface of the redistribution substrate is greater than a distance between a top surface of the sealed portion and the second surface of the redistribution substrate; and wherein the semiconductor device is stacked one on another, the protruding electrodes of the upper semiconductor device are inserted into respective through holes of the lower semiconductor device.
