Patent ID: 8841701

Claim:
A FinFET device comprising: a semiconductor substrate of a first semiconductor material; a fin structure of the first semiconductor material overlying the semiconductor substrate, wherein the fin structure has a top surface of a first crystal plane orientation and a sidewall surface of a third crystal plane orientation; a diamond shape structure of a second semiconductor material disposed over the top surface of the fin structure, wherein the diamond shape structure has a first surface of a second crystal plane orientation and a second surface of the second crystal plane orientation, wherein the first surface of the second crystal plane orientation and the second surface of the second crystal plane orientation intersect each other, wherein the fin structure extends into the diamond shaped structure and the fin structure is without any surface having the second crystal plane orientation wherein the diamond shape structure physically contacts the top surface and the sidewall surface of the fin structure; a gate structure disposed over the diamond shape structure, wherein the gate structure separates a source region and a drain region; and a channel region defined in the diamond shape structure between the source and drain regions.
