  • Publication number: 20110294296
    Abstract: The present invention provides a method for manufacturing a structure over a semiconductor substrate. To form a trench, a patterned layer is formed on a portion of a substrate such that the patterned layer forms a target area located adjacent an edge of the patterned layer. A self-assembled monolayer (SAM) is coupled to the substrate up to the patterned layer, but excluded from the patterned layer. The substrate is then removed within the target area. A wire is formed in a similar fashion except that the first SAM is exchanged with a second SAM in the target area. Then either the substrate outside of the target area is removed, or conductive metal crystals are grown within the target area. Such structures may be advantageously used in the manufacture of a number of active or passive electronic devices, such as a field effect transistor.

  • Publication number: 20080090385
    Abstract: Temperature-sensing compositions can include an inorganic material, such as a semiconductor nanocrystal. The nanocrystal can be a dependable and accurate indicator of temperature. The intensity of emission of the nanocrystal varies with temperature and can be highly sensitive to surface temperature. The nanocrystals can be processed with a binder to form a matrix, which can be varied by altering the chemical nature of the surface of the nanocrystal. A nanocrystal with a compatibilizing outer layer can be incorporated into a coating formulation and retain its temperature sensitive emissive properties.
