Abstract:
A layered chip package includes a main body and wiring. The main body includes a main part including a plurality of stacked layer portions, and a plurality of terminals disposed on the top and bottom surfaces of the main part. The wiring includes a plurality of lines electrically connected to the plurality of terminals. The plurality of lines include a plurality of common lines and a plurality of layer-dependent lines. Each of the plurality of layer portions includes: a plurality of common electrodes electrically connected to the plurality of common lines; a plurality of non-contact electrodes that are electrically connected to the layer-dependent lines and are not in contact with the semiconductor chip in the layer portion; and a selective connection electrode selectively electrically connected to only the layer-dependent line that the layer portion uses among the plurality of layer-dependent lines. The layer-dependent lines are greater than the common lines in maximum width.
