Abstract
A semiconductor device includes a semiconductor substrate and an internal circuitry which is formed on the semiconductor substrate and which executes a predetermined operation. The device also includes a terminal which is connected to the internal circuitry and which receives an external signal and a protection circuitry which is formed on the semiconductor substrate. The protection circuitry includes a transistor having a first region of a first conductivity type, a second region of the first conductivity type and a third region of a second conductivity type. The first region is connected to the terminal. The second region is provided at a scribe line of the semiconductor substrate. The third region is defined by a region between the first region and the second region.
