    摘要: A method for fabricating an integrated device is disclosed. A protective layer is formed over a gate structure when forming epitaxial (epi) features adjacent to another gate structure uncovered by the protective layer. The protective layer is thereafter removed after forming the epitaxial (epi) features. The disclosed method provides an improved method for removing the protective layer without substantial defects resulting. In an embodiment, the improved formation method is achieved by providing a protector over an oxide-base material, and then removing the protective layer using a chemical comprising hydrofluoric acid.
