  • Patent number: 10256392
    Abstract: Techniques for a vertical transmon qubit device are provided. In one embodiment, a chip surface base device structure is provided that comprises a first superconducting material physically coupled to a crystalline substrate, wherein the crystalline substrate is physically coupled to a second superconducting material, wherein the second superconducting material is physically coupled to a second crystalline substrate. In one implementation, the chip surface base device structure also comprises a vertical Josephson junction located in a via of the crystalline substrate, the vertical Josephson junction comprising the first superconducting material, a tunnel barrier, and the second superconducting material. In one implementation, the chip surface base device structure also comprises a transmon qubit comprising the vertical Josephson junction and a capacitor formed between the first superconducting material and the second superconducting material.

  • Patent number: 9472773
    Abstract: A device structure including a gate structure containing a first layer of carbon nanotubes and a second layer of carbon nanotubes. The first and the second layers are stacked vertically. The first and the second layers have carbon nanotubes which have substantially homogeneous electric characteristics within each layer. The carbon nanotubes in the first layer have different electric characteristics than the carbon nanotubes in the second layer, so that the device structure exhibits a multiple threshold behavior when coupled to a voltage source. The disclosure also includes a method for fabricating a multithreshold device structure.

  • Patent number: 7630850
    Abstract: A method for operating an integrated circuit tester information processing system includes: measuring current information from test structures for an integrated circuit having a stress liner; forming a transfer curve by simulating based on the current information with a first range of first mobility multipliers; forming an inverse transfer curve by applying an inverse transfer function to the transfer curve; forming a stress curve with second mobility multipliers from the inverse curve; and validating the second mobility multipliers by comparing a measured curve and a simulated curve with the measured curve based on the current information and the simulated curve based on stress curve.
