  • Patent number: 10418453
    Abstract: A conductive layer is formed between a metal gate structure, which includes a high-k gate dielectric layer and a gate electrode, and a contact feature. The conductive layer can be selectively deposited on a top surface of the gate electrode or, alternatively, non-selectively formed on the top surface of the gate electrode and the gate dielectric layer by controlling, for example, time of deposition. The conductive layer can have a bottom portion embedded into the gate electrode. The conductive layer and the contact feature can include the same composition, though they may be formed using different deposition techniques.

  • Publication number: 20190266708
    Abstract: A method for removing haze from an image is provided. The image is converted to S(x) and V(x), the S(X) is saturation component of the image, and the V(x) is value component of the image. The S(x) is filtered to obtain S?(x), and the V(x) is filtered to obtain V?(x). A depth d(x) is estimated by calculating a difference between the S?(x) and V?(x). Once a transmission map t(x) is calculated based on the d(x), haze is removed from the image based on the transmission map t(x).

  • Publication number: 20180362684
    Abstract: High Mooney viscosity elastomers having low volatiles content, and processes for producing such elastomers, are provided herein. In particular aspects, the elastomers are metallocene-catalyzed elastomers, such as mEPDM elastomers. Processes for producing such elastomers include devolatilization of an elastomer stream comprising such elastomers, using a kneader. The kneader is counterintuitively operated such that the internal agitating paddles rotate at relatively low speeds. It is believed these low speeds help maintain the elastomer stream as a toffee-like composition, preventing the elastomer stream within the kneader from becoming a crumbly composition, which is difficult to devolatilize.
