Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a deep trench capacitor structure comprising a layer stack including:
a first metallic electrode layer;
a second metallic electrode layer; and
at least one node dielectric layer, wherein the node dielectric layer is positioned between the first metallic electrode layer and second metallic electrode layer;

a transistor structure comprising:
a base;
a first terminal formed within the base; and
a second terminal formed within the base;

a first series of connecting structures including via structures and at least one metal interconnect structure electrically connecting the first metallic electrode layer and the first terminal; and
a second series of connecting structures including via structures and at least one metal interconnect structure electrically connecting the second metallic electrode layer and the second terminal, wherein a voltage breakdown value between the first terminal and the second terminal is less than a voltage breakdown value between the first metallic electrode layer and the second metallic electrode layer.
