CONSTITUTION: A semiconductor substrate(100) comprises an active area(104) which is defined by an element isolation film(102). A barrier metal layer(112) is formed on the top side semiconductor substrate. A conductive layer(114) is formed in the top side of the barrier metal layer. A hard mask layer(116) having a width wider than the that of the conductive layer is formed in the conductive layer. . An insulating layer(118) is formed in the sidewall of the hard mask layer.
