Abstract
A semiconductor device includes a semiconductor substrate, at least one semiconductor fin and a gate stack. The semiconductor fin is disposed on the semiconductor substrate. The semiconductor fin includes a first portion, a second portion and a first neck portion between the first portion and the second portion. A width of the first portion decreases as the first portion becomes closer to the first neck portion, and a width of the second portion increases as the second portion becomes closer to a bottom surface of the semiconductor substrate. The gate stack partially covers the semiconductor fin.
