Abstract: A fabrication method for a semiconductor structure at least includes the following steps. First, a pattern mask with a predetermined layout pattern is formed on a substrate. The layout pattern is then transferred to the underneath substrate so as to form at least a fin-shaped structure in the substrate. Subsequently, a shallow trench isolation structure is formed around the fin-shaped structure. Afterwards, a steam oxidation process is carried out to oxidize the fin-shaped structure protruding from the shallow trench isolation and to form an oxide layer on its surface. Finally, the oxide layer is removed completely.
