    摘要: A fin field effect transistor includes a fin protruding from a semiconductor substrate, a gate insulating layer formed so as to cover upper and lateral surfaces of the fin, and a gate electrode formed across the fin so as to cover the gate insulating layer. An upper edge of the fin is rounded so that an electric field concentratedly applied to the upper edge of the fin through the gate electrode is dispersed. A thickness of a portion of the gate insulating layer formed on an upper surface of the fin is greater than a thickness of a portion of the gate insulating layer formed on a lateral surface of the fin, in order to reduce an electric field applied through the gate electrode.

    摘要: A semiconductor device may include an isolation layer, gate electrodes, an insulating interlayer, an impurity region, a capping layer and a plug. The isolation layer may be formed in the substrate. The gate electrodes may be formed on the substrate. The insulating interlayer may be formed on the gate electrodes. The insulating interlayer may have a contact hole between the gate electrodes. The impurity region may be in the substrate exposed through the contact hole. The capping layer may be on the impurity region. The plug may be on the capping layer. Thus, the impurities may not be lost from the impurity region. As a result, the device may have improved electrical characteristics and reliability because depletion may not be generated in the electrode layer
