Abstract: A semiconductor device includes a gate structure and a contact plug. The gate structure extends in a first direction parallel to the substrate, and includes a first conductive pattern, a second conductive pattern and a gate mask sequentially stacked. The contact plug contacts an end portion in the first direction of the gate structure, and includes a first extension portion extending in a vertical direction and contacting sidewalls of the gate mask and the second conductive pattern, a second extension portion under and contacting the first extension portion and a sidewall of the first conductive pattern, and a protrusion portion under and contacting the second extension portion. A bottom of the protrusion portion does not contact the first conductive pattern. A first slope of a sidewall of the first extension portion is greater than a second slope of a sidewall of the second extension portion.

Abstract: Embodiments provide a method that allows users for easily acquire contents information by receiving and displaying only providable contents lists without connecting to servers of a plurality of contents providers, in a network TV that can receive and play contents while being connected with the contents providers.

Abstract: A contents processing device connectable to a network includes a network interface unit configured to request, via the network, contents information from each of a plurality of contents providers, and to receive, via the network, contents information from each of the plurality of contents providers; a user interface unit configured to receive a user input; and a control unit configured to control, based on the user input, displaying of multiple contents windows, and the received contents information corresponding respectively to the plurality of content providers respectively in the multiple contents windows.
