Abstract:
PROBLEM TO BE SOLVED: To provide a method of continuously adjusting the analog electric characteristics of the circuit device, that is, selecting electric characteristics out of a continuous range of analog electric characteristics. SOLUTION: Charge is added to or extracted from an analog unit so as to shift it to a prescribed state before or while a circuit device is driven in a configuration step, the analog electric characteristics of the unit are continuously determined, and the circuit device is driven, taking advantage of the electric characteristics.
Abstract:
Disclosed is, among other things, a method in which a workpiece (14) is fastened to a workpiece support (12) with the aid of connecting means (18, 20), the workpiece (14) and the workpiece support (12) being joined together using an annular connecting means (18, 20). The resulting compound is machined, whereupon the machined workpiece (14) is separated from the workpiece support (12), making it possible to create a particularly simple machining process.

Abstract:
The invention relates to an arrangement of electronic semiconductor components on a carrier system for treating the semiconductor components with a liquid medium. A semiconductor component is detachably mounted on the carrier system with the active side thereof in such a way that the arrangement comprises a gap at least in the edge region and partially between the semiconductor components and the carrier system. The aim of the invention is to provide a detachable arrangement of electronic semiconductor components on a mechanically stable carrier system for safely handling the semiconductor components during the production process, wherein the capillarity of the gap between the semiconductor components and the carrier system is reduced in a controlled manner, thus preventing the damaging effect of a liquid medium seeping into the gap. To this end, the surface of the carrier system is shaped in such a way that the gap is widened along the entire edge region thereof.
Abstract:
The electrical characteristic of a microelectronic circuit configuration that has at least one analog electronic unit is set. In a configuration step, by feeding and/or extracting electrical charge, the analog electronic unit is put into a state which permanently determines the analog electrical characteristics of the unit. In particular, the floating gate of an EEPROM cell is charged up to a freely selectable charge value lying within a continuous range.
Abstract:
Ein Halbleitergehäuse zur doppelseitigen Kühlung umfasst einen ersten und einen zweiten Träger, die einander zugewandt sind, mindestens einen Leistungshalbleiterchip, der zwischen dem ersten und dem zweiten Träger angeordnet ist, externe Kontakte, die mindestens teilweise zwischen dem ersten und dem zweiten Träger angeordnet sind, und Federelemente, die zwischen dem ersten und dem zweiten Träger angeordnet und so konfiguriert sind, dass sie den ersten und den zweiten Träger in einem vordefinierten Abstand voneinander halten.
Abstract:
Ein Verfahren zum Produzieren von Halbleitervorrichtungen im Gehäuse enthält Bereitstellen einer ersten Gehäusesubstratplatte. Eine zweite Gehäusesubstratplatte wird bereitgestellt. Die erste und die zweite Gehäusesubstratplatte werden unter Verwendung eines Steuermechanismus durch eine Fertigungsstraße bewegt, die mehrere Gehäusefertigungswerkzeuge enthält. Halbleitervorrichtungen im Gehäuse vom ersten Typ werden auf der ersten Gehäusesubstratplatte gebildet, und Halbleitervorrichtungen im Gehäuse vom zweiten Typ werden auf der zweiten Gehäusesubstratplatte gebildet. Die Halbleitervorrichtung im Gehäuse vom zweiten Typ ist von der Halbleitervorrichtung im Gehäuse vom ersten Typ verschieden. Der Steuermechanismus bewegt sowohl die erste als auch die zweite Gehäusesubstratplatte auf nichtlineare Weise durch die Fertigungsstraße.
Abstract:
A method and an apparatus for detecting the presence of a work piece in an automatic processing apparatus are described. Previously known detection devices cannot make a clear distinction between the presence and absence of the work piece under all conditions. An apparatus is therefore provided which contains an ultrasound transmitter, an ultrasound receiver and a detection device (controller). The detection as to whether a work piece is held in a holder in the processing apparatus is carried out by irradiating the holder with ultrasound waves, receiving the reflected ultrasound waves and detecting on the basis of the reflected ultrasound waves. The method can be used advantageously in particular in polishing machines for wafers, where the polishing cloth is distinguished considerably, in terms of its acoustic reflection capacity, from the wafer to be polished.
