1. A semiconductor device, comprising:
a substrate, comprising:
a well of type one;a first doped region of type two, provided in the well of type one;a well of type two, adjacent to the well of type one;a first doped region of type one, doped in the well of type two;a third doped region of type one, doped in the well of type one, not touching the first doped region of type two;a third doped region of type two, doped in the well of type two, directly touching the first doped region of type one;a first conductive material, provided on the well of type one and the well of type two but not on the first doped region of type one and the first doped region of type two; anda second conductive layer, provided on the well of type two but not on the first doped region of type one; wherein the substrate comprises no isolating material provided in a current path formed by the first doped region of type two, the well of type one, the well of type two and the first doped region of type one in a sequence. |
