    Abstract: According to one embodiment, a method for fabricating a contact is provided. The method can include a step of depositing a Ti layer in order to completely fill a contact hole and on a surrounding surface of an insulation layer. The method can also include a step of partially converting the Ti layer into a TiN layer in such a manner that a TiN layer is provided on the top side in the contact hole. Further, the method can include a step of polishing back the Ti layer and any remaining TiN layer on the surrounding surface of the insulation layer in a single-stage polishing step.

    Abstract: A method makes contact with a doping region formed at a substrate surface of a substrate. An insulating layer is applied on the substrate surface and a contact hole is formed in the insulating layer. A metal-containing layer is subsequently deposited on the insulating layer and the surface region of the doping region that is uncovered by the contact hole. In a subsequent thermal process having two steps, first the metal-containing layer is reacted with the silicon of the doping region to form a metal silicide layer and then the rest of the metal-containing layer is converted into a metal-nitride-containing layer in a second thermal step.

    Abstract: A discharging device for pharmaceutical liquids having an actuator for carrying out a discharging operation of a pharmaceutical liquid. A first subordinate unit of the actuator has a discharge orifice, and a second subordinate unit is displaceable relative to the first subordinate unit for carrying out the discharging operation. The two subordinate units together delimit a buffer chamber from which a liquid passageway leads to the discharge orifice. A liquid-containing bag is accommodated in the buffer chamber and has film-like walls. The actuator and the bag are coordinated such that displacement of the subordinate units of the actuator relative to each other causes opening of the bag and reduction in the volume of the buffer chamber with consequent volume reduction of the liquid-containing bag and discharge of liquid through the discharge orifice.

    Abstract: A method for determining relevant deposition parameters in i-PVD processes, includes, first calculating the reaction rates for desired reagents of the gas plasma and of a metal and/or metal compound to be deposited, then simulating the edge coverage of a predetermined structure with the deposited metal based upon the calculated reaction rates with systematic variation of the relevant deposition parameters, and compiling variant tables therefrom. By comparing an experimental verification of the simulated edge coverage by imaging the edge coverage of the metal layer deposited over the determined structure, e.g., using a TEM cross-section, with the simulated deposition parameters for the edge coverages that have been recorded in the variant table, it is possible to read the deposition parameters that are of relevance to the process from the variant table.
