Next, a semiconductor device 8 according to some embodiments of present inventive concepts will be described with reference to FIGS. 14 to 16. In the semiconductor device 8, repeated descriptions of the same content as described above may be omitted, and the following description will focus on differences.
FIG. 14 is a perspective view of a semiconductor device 8 according to some embodiments of present inventive concepts, FIG. 15 is a cross-sectional view taken along the line A-A of FIG. 14, and FIG. 16 is a cross-sectional view taken along the line B-B of FIG. 14. The first and second interlayer insulation layers 131 and 132 may be provided in the semiconductor device 8, even if they are not explicitly illustrated in FIG. 14.
Unlike in the semiconductor device 1 shown in FIG. 1, in the semiconductor device 8 shown in FIG. 14, a dummy gate structure 152 is not formed. Instead, a device isolation layer 175 may fill a region that might otherwise be filled with the dummy gate structure 152.
