Abstract: A method of manufacturing a semiconductor device includes forming an active region on a substrate, forming a gate structure on the substrate intersecting the active region, removing an upper portion of the gate structure and forming a gate capping layer, forming a preliminary contact plug electrically connected to a portion of the active region, the preliminary contact plug including first and second portions, forming a mask pattern layer including a first pattern layer covering an upper surface of the gate capping layer, and a second pattern layer extending from the first pattern layer to cover the second portion of the preliminary contact plug, and forming a contact plug using the mask pattern layer as an etch mask by recessing the first portion of the preliminary contact plug exposed by the mask pattern layer to a predetermined depth from an upper surface of the preliminary contact plug.

Abstract: A monitoring device is provided, which includes an inputter configured to receive an input of a plurality of images captured at separate positions and a plurality of sound sources heard at separate positions, a saliency map generator configured to generate a plurality of mono saliency maps for the plurality of images and to generate a dynamic saliency map using the plurality of mono saliency maps generated, a position determinator configured to determine the positions of the sound sources through analysis of the plurality of sound sources, a scan path recognizer configured to generate scan paths of the plurality of images based on the generated dynamic saliency map and the determined positions of the sound sources, and an outputter configured to output the generated scan paths.
