  • Publication number: 20140351779
    Abstract: A method is provided for designing an IC chip. The method includes receiving data from a pre-layout design process for the IC chip, routing a plurality of interconnecting wires to connect various devices of the IC chip, and extracting various circuit parameters. The method also includes simulating the IC chip using the extracted various circuit parameters to detect logic or timing error in the IC chip. The extracting the various circuit parameters includes establishing a statistical interconnect technology profile (ITP) file containing at least interconnect parasitic parameters based on correlations of interconnect layer geometric parameter variations.

  • Publication number: 20140256534
    Abstract: A metal oxide nanorod array structure according to embodiments disclosed herein includes a monolithic substrate having a surface and multiple channels, an interface layer bonded to the surface of the substrate, and a metal oxide nanorod array coupled to the substrate surface via the interface layer. The metal oxide can include ceria, zinc oxide, tin oxide, alumina, zirconia, cobalt oxide, and gallium oxide. The substrate can include a glass substrate, a plastic substrate, a silicon substrate, a ceramic monolith, and a stainless steel monolith. The ceramic can include cordierite, alumina, tin oxide, and titania. The nanorod array structure can include a perovskite shell, such as a lanthanum-based transition metal oxide, or a metal oxide shell, such as ceria, zinc oxide, tin oxide, alumina, zirconia, cobalt oxide, and gallium oxide, or a coating of metal particles, such as platinum, gold, palladium, rhodium, and ruthenium, over each metal oxide nanorod.
