    摘要: Provided is a method and structure for utilizing advance channel substrate materials in semiconductor manufacturing. Advanced channel substrate materials such as germanium and Group III-V channel substrate materials, are advantageously utilized. One or more capping films including at least a nitride layer are formed over the channel substrate prior to patterning, ion implantation and the subsequent stripping and wet cleaning operations. With the capping layers intact during these operations, attack of the channel substrate material is prevented and the protective films are easily removed subsequently. The films are dimensioned in conjunction with the ion implantation operation to enable the desired dopant profile and concentration to be formed in the channel substrate material.

    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.
