    摘要： A method of manufacturing a semiconductor device, including the second sacrificial layer receiving a gate structure include a metal and a spacer on a sidewall of the gate structure therethrough being formed on a substrate. The second sacrificial layer is removed. A second etch stop layer and an insulating interlayer are sequentially formed on the gate structure, the spacer and the substrate. An opening passing through the insulating interlayer is formed to expose a portion of the gate structure, a portion of the spacer and a portion of the second etch stop layer on a portion of the substrate. The second etch stop layer being exposed through the opening is removed. The contact being electrically connected to the gate structure and the substrate and filling the opening is formed. The semiconductor device having the metal gate electrode and the shared contact has a desired leakage current characteristic and resistivity characteristics.

    摘要： Communication between a base station with multiple transmission antennas and a mobile station is provided. The base station and the mobile station may recognize or estimate, respectively, a channel between the base station and the mobile station, and update a previous codebook with a new codebook based on a variation of the channel. In this instance, the mobile station may provide feedback information to the base station using the new codebook, and the base station may generate a transmission signal for the mobile station using the new codebook and the feedback information.

    摘要： A method of forming a pattern includes forming a mask pattern on a substrate; etching the substrate by deep reactive ion etching (DRIE) and by using the mask pattern as an etch mask; partially removing the mask pattern to expose a portion of an upper surface of the substrate; and etching the exposed portion of the upper surface of the substrate. In the method, when a pattern is formed by DRIE, an upper portion of the pattern does not protrude or scarcely protrudes, and scallops of a sidewall of the pattern are smooth, and thus a conformal material layer may be easily formed on a surface of the pattern.
