Claim 0:
1. A semiconductor structure, comprising:
a first base fin and a second base fin extending from a substrate;
an isolation feature disposed between the first base fin and the second base fin;
a first transition epitaxial feature disposed on the first base fin;
a second transition epitaxial feature disposed on the second base fin;
a first bar-like epitaxial feature disposed on the first transition epitaxial feature;
a second bar-like epitaxial feature disposed on the second transition epitaxial feature; and
a conformal epitaxial layer disposed on the first bar-like epitaxial feature and the second bar-like epitaxial feature,
wherein the first bar-like epitaxial feature and the second bar-like epitaxial feature extend upward at an angle between about 65° and about 80° with respect to a top surface of the isolation feature.
