The present invention has an object to provide a semiconductor device, an ID tag, in which delay of signal transmission with conductive layers is controlled. In addition, the other object is that a design method of such a semiconductor device is provided.A semiconductor device of the invention comprises a plurality of conductive layers, a plurality of first element groups each of which selects one among the conductive layers and a plurality of second element groups each of which amplifies a signal each transmitted from the conductive layers. Each of the second element groups is disposed between the first element groups. Stated another way, the first element group and the second element group are disposed alternately. The delay of the signal transmission with the plurality of conductive layers is controlled because a load by a parasitic capacitance is reduced due to the above feature.
