    Abstract: A method of reducing the loss of elements of a photovoltaic thin film structure during an annealing process, includes depositing a thin film on a substrate, wherein the thin film includes a single chemical element or a chemical compound, coating the thin film with a protective layer to form a coated thin film structure, wherein the protective layer prevents part of the single chemical element or part of the chemical compound from escaping during an annealing process, and annealing the coated thin film structure to form a coated photovoltaic thin film structure, wherein the coated photovoltaic thin film retains the part of the single chemical element or the part of the chemical compound that is prevented from escaping during the annealing by the protective layer.

    Abstract: A method and apparatus are described for performing both electroplating of a metal layer and planarization of the layer on a substrate. Electroplating and electroetching of metal (such as copper) are performed in a repeated sequence, followed by chemical-mechanical polishing. An electroplating solution, electroetching solution, and a non-abrasive slurry are dispensed on a polishing pad in the respective process steps. The substrate is held against the pad with a variable force in accordance with the process, so that the spacing between substrate and pad may be less during electroplating than during electroetching.

    Abstract: The device has a base element and a switch element with auxiliary electrodes in the lateral direction. A voltage is applied to electrodes and the auxiliary electrodes to open switch contacts so the electrodes and auxiliary electrodes have first and second potentials, resulting in electrode and auxiliary electrode surface areas with positive and negative charge carriers in the lateral direction and equal charge carriers in the orthogonal direction. The device has a base element and a switch element with auxiliary electrodes (EG,ES) in the lateral direction to which a voltage can be applied. The voltage is applied to electrodes (HG,HS) and the auxiliary electrodes to open switch contacts so the electrodes have a first potential (U1) and the auxiliary electrodes a second potential (U2), resulting in surface areas on the electrodes and auxiliary electrodes with positive and negative charge carriers in the lateral direction and with equal charge carriers in the orthogonal direction. AN Independent claim is also included for the following: a portable terminal with an inventive device.

    Abstract: Es werden Techniken in Bezug auf eine implantierbare Biosensor-Packung bereitgestellt. Eine oder mehrere hierin beschriebene Ausführungsformen können sich zum Beispiel auf eine Vorrichtung beziehen, die ein Biosensor-Modul aufweisen kann. Das Biosensor-Modul kann ein Halbleitersubstrat und einen Prozessor aufweisen. Das Halbleitersubstrat kann einen Sensor aufweisen, der mit dem Prozessor funktionsfähig gekoppelt ist. Die Vorrichtung kann außerdem eine Polymer-Schicht aufweisen. Das Biosensor-Modul kann in der Polymer-Schicht derart eingebettet sein, dass die Polymer-Schicht auf einer Mehrzahl von Seiten des Biosensor-Moduls bereitgestellt sein kann.

    Abstract: Sonden enthalten einen Sondenkörper, der zum Eindringen in biologisches Gewebe geeignet ist. Innerhalb des Sondenkörpers sind Hochleistungs-Lichtquellen angeordnet. Jede Hochleistungs-Lichtquelle hat eine ausreichend hohe optische Ausgangsleistung zum Auslösen einer lichtempfindlichen Reaktion in benachbarten Geweben und die Ausgangsleistung hingegen nicht so hoch sein darf, dass eine gesamte Wärmemenge mehrerer Lichtquellen zu einem störenden Temperaturanstieg in den benachbarten Geweben führen könnte.
