Claim 15:
16. An electrostatic discharge protection device comprising:
a first vertically integrated electrostatic discharge protection structure comprising a first semiconductor portion, a first contact region disposed on a first side of the first semiconductor portion and a first terminal exposed on a second side of the first semiconductor portion opposite the first side of the first semiconductor portion;
a second vertically integrated electrostatic discharge protection structure comprising a second semiconductor portion, a second contact region disposed on a first side of the second semiconductor portion and a second terminal exposed on a second side of the second semiconductor portion opposite the first side of the second semiconductor portion;
an electrical connection layer, wherein the first vertically integrated electrostatic discharge protection structure and the second vertically integrated electrostatic discharge protection structure are disposed on the electrical connection layer laterally separated from each other;
wherein the first electrostatic discharge protection structure comprises at least one first electrical short and a first electrostatic discharge protection device in a parallel arrangement and wherein the second electrostatic discharge protection structure comprises at least one second electrical short and a second electrostatic discharge protection device in a parallel arrangement, wherein the at least one first electrical short and the second electrostatic discharge protection device are coupled in series via the electrical connection layer and wherein the at least one second electrical short and the first electrostatic discharge protection device are coupled in series via the electrical connection layer.
