Abstract:
1. A method of forming a semiconductor device comprising: forming a mask having a plurality of openings atop a semiconductor-containing layer, said semiconductor-containing layer is located atop a substrate; performing an angled ion implantation to introduce dopants to first portions of the semiconductor-containing layer, wherein a first region of a remaining portion of the semiconductor-containing layer is beneath the mask and is substantially free of said dopants, and a second region of the remaining portion of the semiconductor-containing layer that is substantially free of said dopants is present within the plurality of openings and is present between adjacent first portions of the semiconductor-containing layer that are doped; removing the first portion of the semiconductor-containing layer containing the dopants selective to the remaining portion of semiconductor-containing layer that is substantially free of the dopants to provide a pattern; transferring the pattern into the substrate to provide a fin structure having a width of sublithographic dimension; forming a gate structure on a first portion of the fin structure; and forming a source region and a drain region within the fin structure on opposing sides of the first portion of the fin structure to form a finFET device.
