Abstract
A fin-shaped field-effect transistor process includes the following steps. A substrate is provided. A first fin-shaped field-effect transistor and a second fin-shaped field-effect transistor are formed on the substrate, wherein the first fin-shaped field-effect transistor includes a first metal layer and the second fin-shaped field-effect transistor includes a second metal layer. A treatment process is performed on the first fin-shaped field-effect transistor to adjust the threshold voltage of the first fin-shaped field-effect transistor. A fin-shaped field-effect transistor formed by said process is also provided.
