Electronic device

An electrostatic discharge protection device comprising:

• a first vertically integrated ESD 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 ESD 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, and an electrical connection layer;
• wherein the first vertically integrated ESD protection structure and the second vertically integrated ESD protection structure are disposed on the electrical connection layer laterally separated from each other, the electrical connection layer comprises at least one first via embedded in dielectric material contacting the first contact region and at least one second via embedded in dielectric material contacting the second contact region, the electrical connection layer further comprising at least one metal line electrically connecting (e.g. electrically conductively connecting) the least one first via and the least one second via with each other;
• and wherein the electrical connection layer is mounted on a support carrier via at least one adhesive layer.
