Claim 0:
1. An integrated circuit structure, comprising:
a fin having a lower fin portion and an upper fin portion;
a gate stack over the upper fin portion of the fin, the gate stack having a first side opposite a second side;
a first source or drain structure comprising an epitaxial structure embedded in the fin at the first side of the gate stack;
a second source or drain structure comprising an epitaxial structure embedded in the fin at the second side of the gate stack, the epitaxial structures of the first and second source or drain structures each having a vertical trench centered therein, each of the vertical trenches in a portion of the corresponding epitaxial structure that is below a top surface of the fin, and the first and second source or drain structures comprising silicon and a Group V dopant impurity;
a first conductive contact in the vertical trench and on an uppermost surface of the epitaxial structure of the first source or drain structure; and
a second conductive contact in the vertical trench and on an uppermost surface of the epitaxial structure of the second source or drain structure.
