Abstract
A semiconductor device includes a gate structure on a substrate, in which the gate structure includes a main branch extending along a first direction on the substrate and a sub-branch extending along a second direction adjacent to the main branch. The semiconductor device also includes a first doped region overlapping the main branch and the sub-branch according to a top view and a second doped region overlapping the first doped region.
