    Abstract: A method for fabricating a semiconductor device includes forming a pre-isolation layer covering a fin formed on a substrate, the pre-isolation layer including a lower pre-isolation layer making contact with the fin and an upper pre-isolation layer not making contact with the fin, removing a portion of the upper pre-isolation layer by performing a first polishing process, and planarizing the pre-isolation layer such that an upper surface of the fin and an upper surface of the pre-isolation layer are coplanar by performing a second polishing process for removing the remaining portion of the upper pre-isolation layer.
