Patent ID: 8735232

Claim:
A method for forming a semiconductor device, the method comprising: etching a plurality of trenches into a silicon substrate and filling the plurality of trenches with an insulating material to delineate a plurality of spaced apart silicon fins; forming dummy gate structures overlying and transverse to the plurality of spaced apart silicon fins including forming a first dummy gate structure; filling between the dummy gate structures with a back fill material; removing the first dummy gate structure and a first upper portion of the insulating material to expose a first active fins portion of the plurality of spaced apart silicon fins; dimensionally modifying the first active fins portion to form a first altered active fins portion; and depositing a first quantity of high-k dielectric material and a second quantity of work function determining gate electrode material overlying the first altered active fins portion, wherein the work function determining gate electrode material overlies the high-k dielectric material.
