  • Patent number: 6831320
    Abstract: A memory cell configuration connects two trench capacitors to a bit line through a contact bit terminal. Trench capacitors are disposed in a regular grid. Word and bit lines are disposed in a mutually perpendicular crossover structure. An active region in which a selection transistor of an adjoining trench capacitor is introduced is disposed respectively between two trench capacitors of a row. Trench capacitors of two rows are laterally offset with respect to one another. Two active regions of adjacent rows are electrically connected to one another through a connecting line. Connected active regions form a common terminal region connected to a contact bit terminal, which is connected to a bit line. Bit lines are disposed between rows of trench capacitors and parallel thereto. By reducing the contact bit terminals, capacitances of the bit lines are reduced and interference signal transmission between word line and contact bit terminals is reduced.

  • Patent number: 6828680
    Abstract: In an integrated circuit configuration, above a first conductive structure which is embedded in a first insulating layer there are arranged a first barrier layer and a second insulating layer, in which a contact hole is provided which reaches down to the first conductive structure. Above the first barrier layer, the side walls of the contact hole are provided with spacers which act as a diffusion barrier and which reach down to the surface of the first barrier layer. A second conductive structure is arranged in the contact hole. The second conductive structure is conductively connected to the first conductive structure. During the production of the contact hole, the spacers prevent deposition of material from the first conductive structure on the surface of the second insulating layer.

  • Patent number: 6829282
    Abstract: A vertical resonator laser diode and a method for fabricating it are described. Electrical connecting contacts can be disposed on a common main surface of the laser diode, for example its light exit side. For this purpose, in the course of the fabrication method, a contact-making zone is produced by indiffusion of impurity atoms, by which zone that side of the pn junction which is remote from the main surface can be electrically conductively connected to the main surface and be provided with a corresponding connecting contact.

  • Patent number: 6829185
    Abstract: In a semiconductor memory, during the rewriting of the signal stored in a memory cell, a displacement current is produced in the cell capacitor, which has to be supplied by an on-chip plate generator. If a very large number of cell capacitors are simultaneously subjected to charge reversal, as may be necessary in particular during power-up, then the plate generator cannot supply the required current within the predetermined time window. Therefore, the memory cells can assume undesired, incorrect values. It is proposed to precharge the memory cells to a predetermined potential during the switch-on of the operating voltage. Therefore, the displacement current is reduced overall, so that the plate generator can apply the required current for charging the memory cells. This measure prevents a change to the cell contents using simple measures.

  • Patent number: 6828605
    Abstract: A field-effect-controllable semiconductor component has at least one source zone and at least one drain zone of a first conductivity type, and at least one body zone of a second conductivity type. The body zone is provided between the source zone and the drain zone. In each case at least a first and a second region of the second conductivity type are provided in a channel zone. The first region has a first doping concentration and the second region has a second doping concentration, which is lower than the first doping concentration. The combination of the two regions produces a semiconductor component threshold voltage greater than zero and the on resistance is lower than that merely due to a channel zone doped with the first or second doping concentration.

  • Patent number: 6827556
    Abstract: A novel blade configuration does not exceed the permitted stresses for particular loads, especially as a result of centrifugal forces and which at the same time, allows the turbomachine to function with a high degree of efficiency. To this end, a moving blade for the turbomachine contains at least partially a cellular material, especially a foamed metal. The cellular material can be provided e.g. in the hollowed-out part of the moving blade.

  • Patent number: 6827315
    Abstract: The invention relates to a decision procedure in combinational logic which requires a computing time of n for determining the congestion of a railway track system. The railway track system supports n trains, each with a route length of m itineraries. Prior to setting a requested route segment for a given train, a query is performed to check train positions and whether the given train is allowed to travel on the track sectors to be used for the requested route segment, without causing a possibility that the track system may become congested. The processing steps can be reduced. a) verification of whether a train can reach the next immediate track sector of a route; b) verification for a two-train variation whether a reference position of the first train prevents the second train from traveling on its route; c) new dependencies are created using transitivity and for combinations of two trains, a verification is made whether a cogent sequence exists.

  • Patent number: 6826190
    Abstract: A method for controlling a network node and a network having several nodes and terminals. The network node has a plurality of interfaces. One incoming data stream is forwarded from the network node to one of a further network node and a terminal, the network node maintains and stores a connection data stock with connection-related information used to control existing connections to other network nodes, and the connection data stock indicates a data stream designator for an interface and a data stream that is incoming or outgoing at the interface and a data stream direction. Another method uses one terminal as a data source and one as a datasink, each network node forwarding one incoming data stream to one of another network node and a terminal and maintaining a connection data stock with information used to control existing connections to other network nodes, including a data stream designator and a network node interface.

  • Patent number: 6825709
    Abstract: A temperature compensation circuit for a Hall element has a first and a second band gap reference circuit. The Hall element is fed from an excitation current that is proportional to a first reference voltage produced in the first band gap reference circuit. Furthermore, a second band gap reference circuit has a second resistor of a different resistor type than the first resistor. A second reference voltage is dropped across the second resistor. Inputs of a comparator are connected to the Hall sensor and to the second resistor. The comparator compares the Hall voltage with the second reference voltage. The present temperature compensation circuit automatically compensates for manufacturing-dependent and temperature-dependent tolerances.

  • Patent number: 6825116
    Abstract: A method for removing structures from a substrate is described. The method includes providing a substrate that has the structures that must be removed, applying a sacrifice layer, and removing the structures and the sacrifice layer in a polishing step. The method has the advantage that the sacrifice layer surrounds the structures that must be removed and stabilizes them, so that the structures can be eroded slowly and successively in the subsequent polishing step without breaking off. This prevents a smearing of the material of the structures such as occurs given direct polishing without a sacrifice layer.

  • Patent number: 6826075
    Abstract: A memory matrix has at least one cell array including column lines and row lines. Memory elements are situated at points where the row lines and column lines intersect one another. In each case two adjacent lines are guided such that they cross one another in such a way that the two lines change their spatial configurations in sections along the direction in which they run. Thus an overcoupling of signals between the lines is minimized.
