Abstract:
Embodiments of the present disclosure are a method of forming a semiconductor device, a method of forming a FinFET device, a FinFET device. An embodiment a method for semiconductor device, the method comprising forming a first dielectric layer over a substrate, forming a first hardmask layer over the first dielectric layer, and patterning the first hardmask layer to form a first hardmask portion with a first width. The method further comprises forming a first raised portion of the first dielectric layer with the first width, wherein the first raised portion is aligned with the first hardmask portion, and forming a first spacer and a second spacer over the first dielectric layer, wherein the first spacer and the second spacer are on opposite sides of the first raised portion, and wherein the sidewalls of the first spacer and the second spacer are substantially orthogonal to the top surface of the substrate.
