A first dielectric layer covering the epitaxial structure and the substrate is formed. A patterned hard mask layer is formed on the first dielectric layer. A second dielectric layer is formed on the patterned hard mask layer and the first dielectric layer. A patterned photoresist layer is formed on the second dielectric layer. A dry etching process is performed with the pattern hard mask layer and the patterned photoresist layer as masks. The dry etching process forms a contact opening in the first dielectric layer, and the contact opening exposes at least a part of the epitaxial structure. A wet etching process is performed after the dry etching process, and the wet etching process removes the patterned hard mask layer and the second dielectric layer together.
