    摘要: A method of positioning a catalyst nanoparticle that facilitates nanowire growth for nanowire-based device fabrication employs a structure having a vertical sidewall formed on a substrate. The methods include forming the structure, forming a targeted region in a surface of either the structure or the substrate, and forming a catalyst nanoparticle in the targeted region using one of a variety of techniques. The techniques control the position of the catalyst nanoparticle for subsequent nanowire growth. A resonant sensor system includes a nanowire-based resonant sensor and means for accessing the nanowire. The sensor includes an electrode and a nanowire resonator. The electrode is electrically isolated from the substrate. One or more of the substrate is electrically conductive, the nanowire resonator is electrically conductive, and the sensor further comprises another electrode. The nanowire resonator responds to an environmental change by displaying a change in oscillatory behavior.

    摘要: A semiconductor assembly is described in which a support element is constructed on a surface of a semiconductor lamina. Following formation of the thin lamina, which may have a thickness about 50 microns or less, the support element is formed, for example by plating, or by application of a precursor and curing in situ, resulting in a support element which may be, for example, metal, ceramic, polymer, etc. This is in contrast to a rigid or semi-rigid pre-formed support element which is affixed to the lamina following its formation, or to a donor wafer from which the lamina is subsequently cleaved. Fabricating the support element in situ may avoid the use of adhesives to attach the lamina to a permanent support element; such adhesives may be unable to tolerate processing temperatures and conditions required to complete the device. In some embodiments, this process flow allows the lamina to be annealed at high temperature, then to have an amorphous silicon layer formed on each face of the lamina following that anneal. A device may be formed which comprises the lamina, such as a photovoltaic cell.
