Abstract:
A semiconductor device includes first fin-shaped structures and second fin-shaped structures, which are separately disposed on a semiconductor substrate. Each of the first and second fin-shaped structures includes a base portion and a top portion protruding from the top portion. The base portions of the second fin-shaped structures are wider than the top portions of the second fin-shaped structures, and the top portions of the second fin-shaped structures are as wide as the top portions of the first fin-shaped structures. Each second fin-shaped structure further includes a recessed region on its sidewall.

Claim (Index 1):
A method of fabricating a semiconductor device, comprising:\n providing a semiconductor substrate having a first region and a second region; forming a patterned mask in the first and second regions of the semiconductor substrate; etching the semiconductor substrate by using the patterned mask as an etch mask so as to form a patterned structure on the surface of the semiconductor substrate; forming a spacer disposed on the sidewall of the patterned structure in the second region; etching the semiconductor substrate by using the patterned mask and the spacer as an etch mask so as to form a plurality of fin-shaped structures in the first and second regions of the semiconductor substrate; forming a first mask layer covering the fin-shaped structures in the first region; forming an oxide layer on sidewalls of the fin-shaped structures exposed from the first mask layer, the patterned mask and the spacer in the second region; and removing the oxide layer, so that a number of the fin-shaped structures in the second region have base portions narrower than top portions and the other fin-shaped structures in the second region have the base portions wider than the top portions.
