    • A method of manufacturing a vertical-cell-type semiconductor device may include stacking alternately first insulating layers and second insulating layers on a substrate, forming a channel hole through the first and second insulating layers, and forming dielectric layers. A channel layer and a gap fill pattern may be formed within the channel hole. The channel layer may cover a top surface of an uppermost first insulating layer. The top surface of the gap fill pattern is at the same level with the top surface of the channel layer. A first conductivity type impurities may be implanted into the channel layer to form a channel impurity region. A top surface of the gap fill pattern may be recessed. A contact pad on the recessed surface of the gap fill pattern may be formed. A ground selection gate electrode, cell gate electrodes, and string selection gate electrodes may be formed in interlayer spaces that be formed by removing the second insulating layers. String selection gate electrodes may formed in the channel impurity region.
    • 制造垂直单元型半导体器件的方法可以包括在衬底上交替地堆叠第一绝缘层和第二绝缘层,形成通过第一和第二绝缘层的沟道孔,并形成电介质层。 可以在通道孔内形成通道层和间隙填充图案。 沟道层可以覆盖最上面的第一绝缘层的顶表面。 间隙填充图案的顶表面与通道层的顶表面处于同一水平。 可以将第一导电类型的杂质注入到沟道层中以形成沟道杂质区。 间隙填充图案的顶表面可以凹入。 可以形成间隙填充图案的凹陷表面上的接触垫。 可以在通过去除第二绝缘层形成的层间空间中形成接地选择栅电极,单元栅电极和串选择栅电极。 串选择栅电极可以形成在沟道杂质区中。
