Abstract: A semiconductor device includes a semiconductor substrate and a metal structure in electrical contact with the semiconductor substrate. The metal structure has copper as a main component. An encapsulation layer includes a matrix material and a releasable copper corrosion inhibitor dispersed in the matrix material. The matrix material of the encapsulation layer at least partially covers the metal structure. A protective layer is at least partially on and in contact with a surface of the metal structure, and disposed between the metal structure and the encapsulation layer.

Abstract: Disclosed is a potentiometric rod-shaped measuring chain for determining the pH value, comprising a measuring half-cell with a measuring electrode (1) and a reference half-cell with at least one reference electrode (2). In order to be able to carry out a functional check of the measuring chain during the pH measurement, provision is made for a voltammetric measuring cell with a working electrode (4) and a counterelectrode (5) to be additionally provided for the purpose of checking the potential measurement of the measuring chain, wherein the voltammettic measuring cell is connected to a voltammetric evaluation unit.

Abstract: Disclosed is a sensor device (100) for the parallel determination of a concentration of small molecule substances (e.g. ethanol, glucose, etc.) and of a pH value in a solution during the course of a biotechnological process using what is known as cyclic voltammetry. Said sensor device is constructed in the form of a rod electrode. The sensor device consists at least of two rod-shaped working electrodes (102, 103), for which different conductive materials are selected in such a way that distinguishable voltage/current profiles can be determined for the small molecule substances to be determined, and of a rod-shaped reference electrode (104). The working electrodes and the reference electrode are each embedded or melted in a tubular, insulating material. Furthermore, the sensor device comprises a counter electrode (105) in the form of a hollow cylinder, within which the working electrodes and the reference electrode are mounted.
