Classification: CPC H | IPC H

Claim 10:
11. A semiconductor device, comprising:
a substrate;
first and second fins over the substrate and extending upwardly in a first direction;
an epitaxial material comprising a first portion, a second portion, and a third portion, wherein the first portion is located on the first fin, the second portion is located on the second fin, and the third portion is connected to the first and second portions, wherein each of the first and second portions has a top surface bending downward towards the semiconductor substrate in a cross-sectional plane perpendicular to a lengthwise direction of the first and second fins, wherein the third portion has a bottom surface bended upwardly with an apex located between the first and second fins, and wherein in the cross-sectional plane the bottom surface has a first straight line and a second straight line intersecting at the apex; and
a conductive feature in contact with the epitaxial material.
