Abstract:
A method for fabricating a semiconductor device comprises forming a first hardmask, a planarizing layer, and a second hardmask on a substrate. Removing portions of the second hardmask and forming alternating blocks of a first material and a second material over the second hardmask. The blocks of the second material are removed to expose portions of the planarizing layer. Exposed portions of the planarizing layer and the first hardmask are removed to expose portions of the first hardmask. Portions of the first hardmask and portions of the substrate are removed to form a first fin and a second fin. Portions of the substrate are removed to further increase the height of the first fin and substantially remove the second fin. A gate stack is formed over a channel region of the first fin.

Claim (Index 1):
A method for fabricating a semiconductor device, the method comprising:\n forming a first hardmask on a semiconductor substrate; forming a planarizing layer on the first hardmask; forming a second hardmask on the planarizing layer; removing portions of the second hardmask; forming alternating vertical blocks of a first material and a second material over the second hardmask; removing the vertical blocks of the second material to expose portions of the planarizing layer; removing exposed portions of the planarizing layer to expose portions of the first hardmask and removing portions of the first hardmask to expose portions of the semiconductor substrate; removing exposed portions of the semiconductor substrate to form a first fin and a second fin, wherein the first fin is arranged under a portion of the planarizing layer; further removing exposed portions of the semiconductor substrate to further increase the height of the first fin and substantially remove the second fin; and forming a gate stack over a channel region of the first fin.
