The isolation layer includes a trench that is defined and formed in a semiconductor substrate. A first liner nitride layer is formed on the surface of the trench and a flowable insulation layer is formed in the trench including the first liner nitride layer. The flowable insulation layer is formed such to define a recess in the trench. A second liner nitride layer is formed on the recess including the flowable insulation layer and the first liner nitride layer. Finally, an insulation layer is formed in the recess on the second liner nitride layer to completely fill the trench.
