  • Publication number: 20170236753
    Abstract: An integrated circuit includes a silicon-on-insulator wafer and interconnect layer providing a support for a coplanar waveguide formed above a top side of the support. A through-silicon via is formed from a back side of the support and passing through the silicon-on-insulator wafer to reach the interconnect layer. A trench is formed from the back side of the support underneath the coplanar waveguide. The trench extends over at least an entire length of the coplanar waveguide. The trench passes through the silicon-on-insulator wafer to reach the interconnect layer and may have a substantially same depth as the through-silicon via.

  • Patent number: 9710722
    Abstract: Various embodiments provide an optimized image filter. The optimized image and video obtains an input image and selects a target pixel for modification. Difference values are then determined between the selected target pixel and each reference pixel of a search area. Subsequently, a weighting function is used to determine weight values for each of the reference pixels of the search area based on their respective difference value. The selected target pixel is then modified by the optimized image filter using the determined weight values. A new target pixel in an apply patch is then selected for modification. The new target pixel is modified using the previously determined weight values reassigned to a new set of reference pixels. The previously determined weight values are reassigned to the new set of reference pixels based on each of the new set of reference pixels' position relative to the new target pixel.

  • Publication number: 20170194498
    Abstract: A strained semiconductor layer is produced from a semiconductor layer extending on an insulating layer. A thermal oxidization is performed on the semiconductor layer across its entire thickness to form two bars extending in a direction of a transistor width. Insulating trenches are formed in a direction of a transistor length. A strain of the strained semiconductor layer is induced in one implementation before the thermal oxidation is performed. Alternatively, the strain is induced after the thermal oxidation is performed. The insulating trenches serve to release a component of the strain extending in the direction of transistor width. A component of the strain extending in the direction of transistor length is maintained. The bars and trenches delimit an active area of the transistor include source, drain and channel regions.

  • Patent number: 9691871
    Abstract: Local variability of the grain size of work function metal, as well as its crystal orientation, induces a variable work function and local variability of transistor threshold voltage. If the metal nitride for the work function metal of the transistor gate is deposited using a radio frequency physical vapor deposition, equiaxed grains are produced. The substantially equiaxed structure for the metal nitride work function metal layer (such as with TiN) reduces local variability in threshold voltage.
