Patent ID: 8202780

Claim:
A method for manufacturing a FinFET device, comprising: providing a substrate having a mask disposed thereon; covering portions of the mask to define a perimeter of a gate region; removing uncovered portions of the mask to expose the substrate; covering a part of the exposed substrate with another mask to define at least one fin region; forming the at least one fin and the gate region through both masks and the substrate, the gate region having side walls; disposing insulating layers around the at least one fin and onto the side walls; disposing a conductive material into the gate region and onto the insulating layers to form a gate electrode; covering parts of the mask adjacent to ends of the at least one fin, to define source and drain regions; removing uncovered parts of the mask; removing the remaining parts of the mask to produce an intermediate structure; disposing insulating spacers around perimeters of the intermediate structure, and then forming a source and a drain in the source and drain regions.
