Abstract:
A process for fabrication of semiconductor devices, particularly fin-shaped Field Effect Transistors (FinFETs), having a low contact horizontal resistance and a resulting device are provided. Embodiments include: providing a substrate having source and drain regions separated by a gate region; forming a gate electrode having a first length on the gate region; forming an epitaxy layer on the source and drain regions; forming a contact layer having a second length, longer than the first length, at least partially on the epitaxy layer; and forming an oxide layer on top and side surfaces of the contact layer for at least the first length.
