Abstract:
In a method for manufacturing a semiconductor device, a dummy gate layer and a hard mask layer are sequentially formed on a substrate. A first doped portion is formed in the dummy gate layer, and has an etching selectivity with respect to the other portion of the dummy gate layer. Etching masks are formed on portions of the hard mask layer. The hard mask layer and the dummy gate layer are etched to pattern the first doped portion and the other portion of the dummy gate layer into first dummy gates and second dummy gates. The first dummy gates and the second dummy gates have different widths. A dielectric layer is formed to peripherally enclose each of the first dummy gates and each of the second dummy gates. The first dummy gates and the second dummy gates are replaced with first metal gates and second metal gates.

Claim (Index 9):
A semiconductor device comprising:\n a substrate; a fin structure extending from the substrate; two first metal gates extending over the fin structure, each of the respective first metal gates having a first width, the first metal gates being separated by a first pitch; and two second metal gates extending over the fin structure, each of the respective second metal gates having a second width less than the first width, the second metal gates being separated by the first pitch.
