摘要: Techniques are disclosed for incorporating high mobility strained channels into fin-based transistors (e.g., FinFETs such as double-gate, trigate, etc), wherein a stress material is cladded onto the channel area of the fin. In one example embodiment, silicon germanium (SiGe) is cladded onto silicon fins to provide a desired stress, although other fin and cladding materials can be used. The techniques are compatible with typical process flows, and the cladding deposition can occur at a plurality of locations within the process flow. In some cases, the built-in stress from the cladding layer may be enhanced with a source/drain stressor that compresses both the fin and cladding layers in the channel. In some cases, an optional capping layer can be provided to improve the gate dielectric/semiconductor interface. In one such embodiment, silicon is provided over a SiGe cladding layer to improve the gate dielectric/semiconductor interface.

摘要: Techniques are disclosed for forming transistor devices having source and drain regions with high concentrations of boron doped germanium. In some embodiments, an in situ boron doped germanium, or alternatively, boron doped silicon germanium capped with a heavily boron doped germanium layer, are provided using selective epitaxial deposition in the source and drain regions and their corresponding tip regions. In some such cases, germanium concentration can be, for example, in excess of 50 atomic % and up to 100 atomic %, and the boron concentration can be, for instance, in excess of 1E20 cm−3. A buffer providing graded germanium and/or boron concentrations can be used to better interface disparate layers. The concentration of boron doped in the germanium at the epi-metal interface effectively lowers parasitic resistance without degrading tip abruptness. The techniques can be embodied, for instance, in planar or non-planar transistor devices.

摘要: Techniques are disclosed for customization of fin-based transistor devices to provide a diverse range of channel configurations and/or material systems within the same integrated circuit die. In accordance with one example embodiment, sacrificial fins are removed and replaced with custom semiconductor material of arbitrary composition and strain suitable for a given application. In one such case, each of a first set of the sacrificial fins is recessed or otherwise removed and replaced with a p-type material, and each of a second set of the sacrificial fins is recessed or otherwise removed and replaced with an n-type material. The p-type material can be completely independent of the process for the n-type material, and vice-versa. Numerous other circuit configurations and device variations are enabled using the techniques provided herein.
