  • Patent number: 7355218
    Abstract: The source area (3) is highly doped, like the channel area, for the same conductance type. The drain area (4) is doped for the opposite conductance type. This results in a saving of area since the source connection (S) can at the same time be used as the well connection or substrate connection.

    Abstract: The invention proposes an apparatus for writing to and/or reading from a memory cell in a semiconductor memory having a selection transistor and a storage capacitor, where the apparatus has a device which is used to influence a threshold voltage for the selection transistor contrary to the influence of an ambient temperature. The invention also proposes a method for writing to and/or reading from a memory cell in a semiconductor memory having a selection transistor and a storage capacitor, where the method comprises the following method steps: a) an ambient temperature for the memory cell is ascertained, and b) an electrical voltage is applied to a substrate well in the selection transistor as a function of the ascertained ambient temperature such that a threshold voltage for the selection transistor is influenced contrary to the influence of an ambient temperature.

  • Patent number: 6986088
    Abstract: The invention relates to a method for reducing the current consumption of an electronic circuit having at least one test module for testing the electronic circuit. The test module is connected to at least one line and/or a connection of the electronic circuit. A test control signal is generated, by means of which the test module is at least partially decoupled from the line or the connection in an operating mode of the electronic circuit such that switching currents are prevented in the test module.

  • Patent number: 6977862
    Abstract: Address decoding circuit and method for addressing a regular memory area and a redundant memory area in a memory circuit are provided. One embodiment provides a method for addressing memory areas in a memory circuit with successive addresses, with either a regular memory area or a redundant memory area being addressed depending on the address, with an inactive state of a deactivation signal being set when addressing the regular memory area, which inactive state allows the addressing of the regular memory area, with the addressing of the regular memory area being blocked on the basis of an active state of the deactivation signal when addressing the redundant memory area, wherein a change is made from the active state of the deactivation signal to the inactive state of the deactivation signal before the application of the next address for addressing one of the memory areas.

  • Patent number: 6821187
    Abstract: The invention discloses a method for the chemical-mechanical polishing of layers composed of metals of the group of platinum metals, particularly iridium. In the CMP process, high erosion rates for iridium and a high selectivity relative to silicon oxide are achieved upon employment of a polishing fluid that contains 1 through 6% by weight abrasive particles, 2 through 20% by weight of at least one oxidation agent selected from the group comprising Ce(IV) salts, salts of chloric acid, salts of peroxodisulfuric acid, hydrogen peroxide and salts of hydrogen peroxide, and 74 through 97% by weight water. This enables the structuring of iridium layers with the assistance of an oxide mask and a CMP process.
