Abstract:
A semiconductor device includes a substrate, at least two gate spacers, and a gate stack. The substrate has at least one semiconductor fin. The gate spacers are disposed on the substrate. At least one of the gate spacers has a sidewall facing to another of the gate spacers. The gate stack is disposed between the gate spacers. The gate stack includes a high-κ dielectric layer and a gate electrode. The high-κ dielectric layer is disposed on the substrate and covers at least a portion of the semiconductor fin while leaving the sidewall of said at least one gate spacer uncovered. The gate electrode is disposed on the high-κ dielectric layer.

Claim (Index 8):
A method for manufacturing a semiconductor device, the method comprising:\n forming a dummy layer over a substrate, the substrate having a fin; patterning the dummy layer to form a first dummy structure; forming a first insulating structure on a first side of the first dummy structure and a second insulating structure on a second side of the first dummy structure; removing a first portion of the first dummy structure and a second portion of the first dummy structure to form a second dummy structure; forming a third insulating structure on a first sidewall of the second dummy structure and a fourth insulating structure on a second sidewall of the second dummy structure; removing the second dummy structure to form a recess; and forming a gate structure in the recess, wherein the gate structure is bounded by the first insulating structure, the second insulating structure, the third insulating structure, and the fourth insulating structure in a plan view.
