Patent ID: 7429505

Claim:
A method of fabricating a FinFET, the method comprising: forming a hard mask pattern on a semiconductor substrate; etching the semiconductor substrate, using the hard mask pattern as an etching mask, to form a trench therein, the trench defining an active region; forming an isolation layer that fills the trench and covers sidewalls of the hard mask pattern; forming a photoresist pattern having a groove extending across the hard mask pattern; etching the isolation layer, using the photoresist pattern and the hard mask pattern as an etching mask, to expose both sidewalls of the active region; removing the photoresist pattern; recessing sidewalls of the exposed active region to form a fin; removing the hard mask pattern to expose an upper surface of the fin; and forming a gate electrode that covers the exposed upper surface and sidewalls of the fin, wherein the gate electrode is insulated from the fin.
