Claim 9:
10. 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;
a conformal epitaxial layer disposed on the first bar-like epitaxial feature and the second bar-like epitaxial feature;
a first spacer disposed on the isolation feature and along sidewalls of the first base fin and the first transition epitaxial feature;
a second spacer disposed on the isolation feature and along sidewalls of the second base fin and the second transition epitaxial feature; and
a slit between the first spacer and the second spacer.
