Abstract:
1. A semiconductor device comprising: (a) a first area disposed over a semiconductor substrate; (b) one or more first wiring lines formed over the signal line and disposed in the first area; and (c) second wiring lines formed over the signal line and disposed in the first area, the second wiring lines being formed in a layer different from a layer in which the first wiring lines are formed, wherein the first and second wiring lines are wiring lines for supply voltage, respectively, wherein each of the first wiring lines is connected to a detector circuit, which is configured to be used for detection of tampering with the first wiring lines and which is comprised of the second semiconductor elements, wherein, when any of the first wiring lines are subjected to processing, the detector circuit operates to make the first semiconductor elements unable to operate, and wherein the first wiring lines are located in a lower wiring layer, closer to the substrate, than the second wiring lines.
