Patent ID: 8592910

Claim:
A semiconductor body comprising: a protective structure comprising: a first region and a second region which have a first conductivity type, a third region that has a second conductivity type opposite the first conductivity type, wherein the third region is constructed as a first well and with floating potential, the third region having no ohmic contact to a path conductor, an insulator that is arranged on the semiconductor body, and an electrode that is arranged on the insulator and is completely encapsulated by insulating material, wherein the first and the second regions are arranged spaced apart in the third region, so that a current flow from the first region to the second region is made possible for the limiting of a voltage difference between the first and the second regions and the semiconductor body comprises a deep well in which the third region is arranged; a structure that is to be protected by and operatively coupled to the protective structure; a first path conductor; and a second path conductor, wherein the first path conductor connects the first region of the protective structure to a terminal of the structure that is to be protected in an electrically conductive way, and the second path conductor connects the second region of the protective structure to a supply voltage terminal in an electrically conductive way.
