Abstract:
Methods of forming electrical interconnects include forming a copper pattern on a semiconductor substrate and then forming an electrically insulating capping layer on the copper pattern and an interlayer insulating layer on the electrically insulating capping layer. A contact hole is then formed, which extends through the interlayer insulating layer and the electrically insulating capping layer and exposes an upper surface of the copper pattern. An electroless plating step is then performed to form a copper pattern extension onto the exposed upper surface of the copper pattern. The copper pattern extension may have a thickness that is less than a thickness of the electrically insulating capping layer, which may be formed as a SiCN layer.
Abstract:
A wireless broadband Internet (WiBro) terminal and a method of determining a sleep mode of a WiBro terminal, which can measure a strength of a preamble signal and determine an effective sleep interval are provided. A WiBro terminal, which can measure a strength of a preamble signal in the listening mode during an L frame after operating in a sleep mode during an N1 frame, and operate in a sleep mode during either an N1 or 2*N1 frames, or perform a normal operation when MOB_TRF_IND is positive, resulting from the comparing the strength with a threshold value, is provided.
Abstract:
Provided is a home-bar door and a method of manufacturing the home-bar door. The home-bar door includes a first case, an insulating plate, and a second case. The first case forms a portion of an exterior of the home-bar door, and the insulating plate is disposed in the first case as a separate component. The second case is configured to be coupled to the first case to cover the insulating plate and form the exterior of the home-bar door. Therefore, since the first and second cases can be coupled to each other after disposing the insulating plate between the first and second cases, the home-bar door can be efficiently manufactured and have good quality.
