According to the method, a capping insulation pattern may be formed to cover the top surface of a filling insulation pattern in a trench. The capping insulation pattern may have an etch selectivity according to the filling insulation pattern. As a result, the likelihood that the filling insulation layer may be etched by various cleaning processes and the process removing the buffer insulation pattern may be reduced or prevented.
