Abstract
A semiconductor device that includes at least one germanium containing fin structure having a length along a <100> direction and a sidewall orientated along the (100) plane. The semiconductor device also includes at least one germanium free fin structure having a length along a <100> direction and a sidewall orientated along the (100) plane. A gate structure is present on a channel region of each of the germanium containing fin structure and the germanium free fin structure. N-type epitaxial semiconductor material having a square geometry present on the source and drain portions of the sidewalls having the (100) plane orientation of the germanium free fin structures. P-type epitaxial semiconductor material having a square geometry is present on the source and drain portions of the sidewalls having the (100) plane orientation of the germanium containing fin structures.
