Abstract
Generally, examples described herein relate to methods and semiconductor processing systems for anisotropically epitaxially growing a material on a silicon germanium (SiGe) surface. In an example, a surface of silicon germanium is formed on a substrate. Epitaxial silicon germanium is epitaxially grown on the surface of silicon germanium. A first growth rate of the epitaxial silicon germanium is in a first direction perpendicular to the surface of silicon germanium, and a second growth rate of the epitaxial silicon germanium is in a second direction perpendicular to the first direction. The first growth rate is at least 5 times greater than the second growth rate.
