Patent ID: 8633076

Claim:
A method of fabricating a FinFET device comprising: forming a first mandrel having a first sidewall and an opposing second sidewall, forming a second mandrel having a third sidewall and an opposing fourth sidewall; wherein a space interposes the first and second mandrels, and wherein the space has a first width and is defined by the second sidewall and the third sidewall; forming a first spacer element abutting the first sidewall, a second spacer element abutting the second sidewall, a third spacer element abutting the third sidewall, and a fourth spacer element abutting the fourth sidewall; wherein the second spacer element contacts the third spacer element to form a contiguous enlarged spacer element having the first width; using the contiguous enlarged spacer element to form a first fin structure having the first width; and forming a second fin structure using at least one of the first spacer element and the fourth spacer element.
