  • Publication number: 20160064273
    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.

  • Publication number: 20150249078
    Abstract: An integrated circuit having an ESD protection structure is described. One embodiment includes a circuit section interconnected with a first terminal and with a second terminal and being operable at voltage differences between the first terminal and second terminal of greater than +10 V and less than ?10 V. The integrated circuit additionally includes an ESD protection structure operable to protect the circuit section against electrostatic discharge between the first terminal and the second terminal. The ESD protection structure is operable with voltage differences between the first and second terminals of greater than +10 V and less than ?10 V without triggering. The ESD protection structure is electrically and optically coupled to a photon source such that photons emitted by the photon source upon ESD pulse loading are absorbable in the ESD protection structure and an avalanche breakdown is initiatable by electron-hole pairs generated by the absorbed photons.
