    摘要: A highly selective metal wet etchant with an active ingredient comprising one or more types of molecules having two or more oxygen atoms is described. In one embodiment, the wet etchant is utilized to pattern a metal layer in a semiconductor structure. In another embodiment, a highly selective metal wet etchant with an active ingredient comprising one or more types of molecules having two or more oxygen atoms is used to pattern a metal gate electrode in a replacement gate processing scheme.

    摘要: Modulation-doped multi-gate devices are generally described. In one example, an apparatus includes a semiconductor substrate having a surface, one or more buffer films coupled to the surface of the semiconductor substrate, a first barrier film coupled to the one or more buffer films, a multi-gate fin coupled to the first barrier film, the multi-gate fin comprising a source region, a drain region, and a channel region of a multi-gate device wherein the channel region is disposed between the source region and the drain region, a spacer film coupled to the multi-gate fin, and a doped film coupled to the spacer film.
