Abstract: A method for manufacturing a semiconductor device includes forming a first dielectric layer over a semiconductor fin. The method includes forming a second dielectric layer over the first dielectric layer. The method includes exposing a portion of the first dielectric layer. The method includes oxidizing a surface of the second dielectric layer while limiting oxidation on the exposed portion of the first dielectric layer.

Abstract: A welfare-oriented raising house for meat-type ducks, including a raising house, is provided. The raising house is internally provided with a support frame which is of a U-shaped structure and arranged in a length direction of the raising house, a raising net arranged at a top of the support frame, a cleaning and storing mechanism arranged at one end of the support frame for cleaning and storing the raising net, a traction mechanism arranged at the other end of the support frame for the traction of the raising net, blocking mechanisms which are of a zigzag structure and arranged at both sides of the support frame, and tensioning vibration mechanisms arranged at bottoms of the blocking mechanisms and fixedly connected to a side edge of the support frame.

Abstract: The present disclosure discloses a method and apparatus for mining community users, belonging to the field of Internet communications. The method includes: acquiring original community data of a community user; calculating intimacy scores of the community user with respect to other community users according to the original community data of the community user, the intimacy scores being used for indicating degrees of intimacy of the community user with respect to the other community users; clustering the community users according to the intimacy scores of the community user with respect to the other community users, and forming a community user circle; and displaying the community user circle to community users in the community user circle, so that the community users in the community user circle communicate with each other. The apparatus includes: a first acquiring module, a calculation module, a clustering module, and a display module.

Abstract: An illumination system defined a primary optical axis is provided. The illumination system comprises a light source, a first lens group, an integrator rod, and a second lens group successively located on the primary optical axis. The light source is configured to output a light. The first lens group is configured to reduce an aperture angle of the light to about 27 degrees. The integrator rod is configured to make the light uniformly. The second lens group is configured to amplify an illumination field of the light and reduce the aperture angle of the light to about 3 degrees.

Abstract: An information recommendation method is provided for a terminal. The method includes obtaining at least one keyword, obtaining geographical location information corresponding to the keyword, and searching, within a range of a map interface display area, recommendation information relevant to geographical locations adjacent to the geographical location corresponding to the geographical location information. The method also includes displaying, according to the range of the map interface display area, geographical location information corresponding to the keyword, as well as the map interface having the recommendation information.
