摘要:
A method of forming a finFET transistor using a sidewall epitaxial layer includes forming a silicon germanium (SiGe) layer above an oxide layer above a substrate, forming a cap layer above the SiGe layer, removing portions of the SiGe layer and the cap layer to form a feature, forming sidewalls along lateral walls of the feature, and removing the feature.
