Abstract: A semiconductor component has integrated a coreless transformer with a first connection contact, a second connection contact, an electrically conductive spiral first coil, an electrically conductive first ring, and an electrically conductive second ring. The electrically conductive spiral first coil is electrically connected between the first connection contact and the second connection contact. The electrically conductive first ring surrounds the first coil and one or both of the first connection contact and the second connection contact. The electrically conductive second ring is arranged between the first coil and the first ring, electrically connected to the first coil, and surrounds the first coil and one or both of the first connection contact and the second connection contact.

Abstract: A method for producing a rounded conductor line of a semiconductor component is disclosed. In that method, a partially completed semiconductor component is provided. The partially completed semiconductor component has a bottom side and a top side spaced distant from the bottom side in a vertical direction. Also provided is an etchant. On the top side, a dielectric layer is arranged. The dielectric layer has at least two different regions that show different etch rates when they are etched with the etchant. Subsequently, a trench is formed in the dielectric layer such that the trench intersects each of the different regions. Then, the trench is widened by etching the trench with the etchant at different etch rates. By filling the widened trench with an electrically conductive material, a conductor line is formed.
