Abstract
A semiconductor device includes a first gate stack over a substrate. The semiconductor device further includes a first epitaxial (epi) material in the substrate on a first side of the first gate stack. The first epi material includes a first upper surface having a first crystal plane. The semiconductor device further includes a second epi material in the substrate on a second side of the first gate stack opposite the first side. The second epi material includes a second upper surface having a second crystal plane, and the first crystal plane is different from the second crystal plane.
