  • Publication number: 20060133172
    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: 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: 6413866
    Abstract: A method of enriching the surface of a substrate with a solute material that was originally dissolved in the substrate material, to yield a uniform dispersion of the solute material at the substrate surface. The method generally entails the use of a solvent material that is more reactive than the solute material to a chosen reactive agent. The surface of the substrate is reacted with the reactive agent to preferentially form a reaction compound of the solvent material at the surface of the substrate. As the compound layer develops, the solute material segregates or diffuses out of the compound layer and into the underlying substrate, such that the region of the substrate nearest the compound layer becomes enriched with the solute material. At least a portion of the compound layer is then removed without removing the underlying enriched region of the substrate.

  • Patent number: 6221757
    Abstract: A microelectronic structure is formed on a first layer or a substrate. The first layer or substrate is formed with grooves and contact openings. A metal nitride layer of TiN or WN covers the first layer or the substrate at least partially. An alpha-phase tantalum layer is deposited on top of the metal nitride layer. Finally, a metal is deposited to completely fill the grooves and the contact openings.

  • Patent number: 5972787
    Abstract: The method of polishing metal layers on wafers comprises the steps of: providing indicator areas on said wafer, said indicator areas having combinations of line widths and pattern factors violating existing ground rules of metal lines thereby said indicator areas being dished out during said polishing using a chemical-mechanical polisher to polish the metal layers to remove material therefrom, inspecting indicator areas on the wafer to determine an amount of material removed from said areas, and adjusting the operation of the chemical-mechanical polisher in response to the inspection of the indicator areas. The indicator areas may include macroblocks comprised of a multitude of individual blocks. The wafer may be inspected by optically identifying the polishing state of to blocks in the macroblock. Additionally, the process may be automated for mass production.
