    Abstract: A method for forming an isolation structure includes the following steps. A hard mask layer is formed on a substrate and a trench is formed in the substrate and the hard mask layer. A protective layer is formed to cover the trench and the hard mask layer. A first isolation material is filled into the trench. An etching process is performed to etch back part of the first isolation material.
