摘要： An ambient environment nanowire sensor and corresponding fabrication method have been provided. The method includes: forming a substrate such as Silicon (Si) or glass; growing nanowires; depositing an insulator layer overlying the nanowires; etching to expose tips of the nanowires; forming a patterned metal electrode, with edges, overlying the tips of the nanowires; and, etching to expose the nanowires underlying the electrode edges. The nanowires can be a material such as IrO2, TiO2, InO, ZnO, SnO2, Sb2O3, or In2O3, to mane just a few examples. The insulator layer can be a spin-on glass (SOG) or low-k dielectric. In one aspect, the resultant structure includes exposed nanowires grown from the doped substrate regions and an insulator core with embedded nanowires. In a different aspect, the method forms a growth promotion layer overlying the substrate. The resultant structure includes exposed nanowires grown from the selectively formed growth promotion layer.

摘要： A method is provided for patterning iridium oxide (IrOx) nanostructures. The method comprises: forming a substrate first region adjacent a second region; growing IrOx nanostructures from a continuous IrOx film overlying the first region; simultaneously growing IrOx nanostructures from a non-continuous IrOx film overlying the second region; selectively etching areas of the second region exposed by the non-continuous IrOx film; and, lifting off the IrOx nanostructures overlying the second region. Typically, the first region is formed from a first material and the second region from a second material, different than the first material. For example, the first material can be a refractory metal, or refractory metal oxide. The second material can be SiOx. The step of selectively etching areas of the second region exposed by the non-continuous IrOx film includes exposing the substrate to an etchant that is more reactive with the second material than the IrOx.
