    摘要: Provided are a method of forming an insulating layer and a method of manufacturing a transistor using the method. The method of forming the insulating layer includes forming a preliminary insulating layer including silicon oxide (SiO2) on a silicon (Si)-containing substrate. A reactive gas containing ammonia (NH3) gas is supplied to the preliminary insulating layer. Nitrogen radicals (N*) and hydrogen radicals (H*) are generated from the ammonia gas using plasma. The hydrogen radicals combine with oxygen of the preliminary insulating layer, and the nitrogen radicals combine with the silicon oxide so that an insulating layer including hydroxides (OH) and silicon oxynitride (SiON) can be formed.

    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: First and second preliminary epitaxial layers are grown from single-crystalline seeds in openings in an insulation layer until the first and second epitaxial layers are connected to each other. While the first and second preliminary epitaxial layers are being grown, a connection structure of a material having an amorphous state is formed on a portion of the insulation layer located between the first and second preliminary epitaxial layers. The material having an amorphous state is then changed into material having a single-crystalline state. Thus, portions of the first and second epitaxial layers are connected to each other through the connection structure so that the epitaxial layers and the connection structure constitute a single-crystalline structure layer that is free of voids for use as a channel layer or the like of a semiconductor device.
