摘要
A semiconductor device includes a semiconductor substrate having a plurality of semiconductor fins formed on an upper surface thereof. An epitaxial material is formed on the upper surface of the semiconductor substrate and on an outer surface of the semiconductor fins. The epitaxial material includes an epi upper surface having a lower region that contacts the semiconductor fins and an upper region formed above the lower region. The upper region extends parallel with an upper surface of the semiconductor fins.
