Abstract
A semiconductor device comprising a substrate is disclosed. The substrate comprises: 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; and a first doped region of type one, doped in the well of type two. 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.
