  • INNER L-SPACER FOR REPLACEMENT GATE FLOW
    Publication number: 20150069516
    Abstract: An integrated circuit is formed by removing a sacrificial gate dielectric layer and a sacrificial gate to form a gate cavity. A conformal dielectric first liner is formed in the gate cavity and a conformal second liner is formed on the first liner. A first etch removes the second liner from the bottom of the gate cavity, leaving material of the second liner on sidewalls of the gate cavity. A second etch removes the first liner from the bottom of the gate cavity exposed by the second liner, leaving material of the first liner on the bottom of the gate cavity under the second liner on the sidewalls of the gate cavity. A third etch removes the second liner from the gate cavity, leaving an L-shaped spacers of the first liner in the gate cavity. A permanent gate dielectric layer and replacement gate are formed in the gate cavity.

    Patent number: 8928731
    Abstract: A panorama photography method and apparatus is provided to inform a use of an optimum photographing position for the next photograph when capturing in succession several adjacent photographs to obtain a combined panorama photograph. In the method, after a first image is captured, a guide image is generated from a predefined section of the first image, and a first edge is detected in the guide image. A preview image is acquired for a second image to be captured, and a second edge is detected in the preview image. The second edge is obtained from a predefined part of the preview image that coincides with the guide image. Based on comparison between the first and second edges, notification data are generated and outputted together with a synthetic image of the guide image and the preview image.
