Abstract:
Methods to achieve strained channel finFET devices and resulting finFET devices are presented. In an embodiment, a method for processing a field effect transistor (FET) device may include forming a fin structure comprising a fin channel on a substrate. The method may also include forming a sacrificial epitaxial layer on a side of the fin structure. Additionally, the method may include forming a deep recess in a region that includes at least a portion of the fin structure, wherein the fin structure and sacrificial layer relax to form a strain on the fin channel. The method may also include depositing source/drain (SD) material in the deep recess to preserve the strain on the fin channel.
