    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

    摘要: In plasma ion doping operations, a wafer is positioned on a susceptor within a reaction chamber and an ion doping source gas is plasmalyzed in an upper part of the reaction chamber above a major surface of the wafer while supplying a control gas into the reaction chamber in a lower part of the reaction chamber opposite the major surface of the wafer to thereby dope ions into the major surface of the wafer. The ion doping source gas may comprise at least one halide gas, and the control gas may comprise at least one depositing gas, such as a silane gas. In further embodiments, a diluent gas, such as an inert gas, may be supplied to the reaction chamber while supplying the ion doping source gas and the control gas. Related plasma ion doping apparatus are described.
