Abstract

A semiconductor device includes a semiconductor substrate having a channel region therein, a gate structure above the channel region, and source and drain regions on opposite sides of the gate structure. A respective contact is on each of the source and drain regions. At least one of the source and drain regions has an inclined upper contact surface with the respective contact. The inclined upper contact surface has at least a 50% greater area than would a corresponding flat contact surface.
