Abstract
A method for fabricating a semiconductor device includes forming a pre-fin extending in a first direction, the pre-fin including first, second, and third regions, forming first and second gates on the pre-fin to extend in a second direction intersecting the first direction, the first and second gates being spaced apart from each other in the first direction and overlapping with the first and second regions, respectively, forming first and second dummy spacers on the first and second regions, respectively to form a first trench in the third region that exposes the third region, forming a second trench by etching the exposed third region using the first and second dummy spacers as masks to separate the pre-fin into first and second active fins corresponding to the first and second regions, respectively, forming a dummy gate by filling the first and second trenches and removing the first and second dummy spacers.
