Abstract
A layered chip package includes a plurality of layer portions that are stacked, each of the layer portions including a semiconductor chip. The plurality of layer portions include at least one first-type layer portion and at least one second-type layer portion. The semiconductor chip has a circuit, a plurality of electrode pads electrically connected to the circuit, and a plurality of through electrodes. In every vertically adjacent two of the layer portions, the plurality of through electrodes of the semiconductor chip of one of the two layer portions are electrically connected to the respective corresponding through electrodes of the semiconductor chip of the other of the two layer portions. The first-type layer portion includes a plurality of wires for electrically connecting the plurality of through electrodes to the respective corresponding electrode pads, whereas the second-type layer portion does not include the wires.
