  • Patent number: 9006906
    Abstract: A capacitor is formed in nano channels in a conductive body. Embodiments include forming a source contact through a first inter layer dielectric (ILD), forming a conductive body on the first ILD, forming a second ILD on the conductive body, forming drain and gate contacts through the second ILD, conductive body, and first ILD, forming nano channels in the conductive body, forming an insulating layer in the channels, and metalizing the channels. An embodiment includes forming the nano channels by forming a mask on the second ILD, the mask having features with a pitch of 50 nanometers (nm) to 100 nm, etching the second ILD through the mask, etching the conductive body through the mask to a depth of 80% to 90% of the thickness of the conductive body, and removing the mask.

  • Patent number: 8925396
    Abstract: During the fabrication of microstructure devices, such as integrated circuits, particles may be analyzed by displacing or removing the particles from the device surface and subsequently performing an analysis process. Consequently, a well-defined measurement environment may be established after removal of the particles, which may be accomplished on the basis of nanoprobes and the like. Hence, even critical surface areas may be monitored with respect to contamination and the like on the basis of well-established analysis techniques.

  • Patent number: 8435885
    Abstract: Analysis of chemical and physical characteristics of polymer species and etch residues caused in critical plasma-assisted etch processes for patterning material layers in semiconductor devices may be accomplished by removing at least a portion of these species on the basis of a probing material layer, which may be lifted-off from the patterned surface. The probing material layer may substantially suppress a chemical modification of the species of interest and may thus allow the examination of the initial status of these species.

  • Publication number: 20100248498
    Abstract: A sacrificial material, such as resist material, polymer material, organic residues and the like, may be efficiently removed from a surface of a semiconductor device by evaporating the material under consideration, which may, for instance, be accomplished by energy deposition. For example, a laser beam may be scanned across the surface to be treated so as to evaporate the sacrificial material, such as resist material, while significantly reducing any negative effects on other materials such as dielectrics, metals, semiconductive materials and the like. Moreover, by selecting an appropriate scan regime, a locally selective removal of material may be accomplished in a highly efficient manner.

  • Patent number: 7375031
    Abstract: By improving the purity of metal lines and the crystalline structure, the overall performance of metal lines, especially of highly scaled copper-based semiconductor devices, may be enhanced. The modification of the crystalline structure of the metal lines may be performed by a heat treatment generating locally restricted heating zones, which are scanned along the length direction of the metal lines, and/or a heat treatment comprising a heating step in a vacuum ambient followed by a heating step in a reducing ambient.
