摘要： Thin silicon channel SOI devices provide the advantage of sharper sub-threshold slope, high mobility, and better short-channel effect control but exhibit a typical disadvantage of increased series resistance. This high series resistance is avoided by using a raised source-drain (RSD), and expanding the source drain on the pFET transistor in the CMOS pair using selective epitaxial Si growth which is decoupled between nFETs and pFETs. By doing so, the series resistance is improved, the extensions are implanted after RSD formation and thus not exposed to the high thermal budget of the RSD process while the pFET and nFET can achieve independent effective offsets.

摘要： A method for preventing polysilicon stringer formation under the active device area of an isolated ultra-thin Si channel device is provided. The method utilizes a chemical oxide removal (COR) processing step to prevent stinger formation, instead of a conventional wet etch process wherein a chemical etchant such as HF is employed. A silicon-on-insulator (SOI) structure is also provided. The structure includes at least a top Si-containing layer located on a buried insulating layer; and an oxide filled trench isolation region located in the top Si-containing layer and a portion of the buried insulating layer. No undercut regions are located beneath the top Si-containing layer.
