Abstract: A method for forming a semiconductor device is provided. The method includes forming a semiconductor protruding structure over a substrate and surrounding the semiconductor protruding structure with an insulating layer. The method also includes forming a dielectric layer over the insulating layer. The method further includes partially removing the dielectric layer and insulating layer using a planarization process. As a result, topmost surfaces of the semiconductor protruding structure, the insulating layer, and the dielectric layer are substantially level with each other. In addition, the method includes forming a protective layer to cover the topmost surfaces of the dielectric layer. The method includes recessing the insulating layer after the protective layer is formed such that the semiconductor protruding structure and a portion of the dielectric layer protrude from a top surface of a remaining portion of the insulating layer.

Abstract: A semiconductor device and method of manufacture are provided. In embodiments a first liner is deposited to line a recess between a first semiconductor fin and a second semiconductor fin, the first liner comprising a first material. The first liner is annealed to transform the first material to a second material. A second liner is deposited to line the recess, the second liner comprising a third material. The second liner is annealed to transform the third material to a fourth material.

Abstract: Semiconductor devices and methods of manufacturing are presented in which inner spacers for nanostructures are manufactured. In embodiments a dielectric material is deposited for the inner spacer and then treated. The treatment may add material and cause an expansion in volume in order to close any seams that can interfere with subsequent processes.

Abstract: The method for searching a video event includes: capturing a video; obtaining multiple pixels corresponding to the video; calculating a pixel difference value of each pixel by comparing frames at different timestamps in the video; dividing the video into multiple video segments, each video segment including a group of frames; determining a representative value for each pixel in each video segment according to the pixel difference value of each pixel; generating a metadata file which records the representative value for each pixel in each video segment; and searching an event in the video according to the metadata file.
