Abstract
A semiconductor device and a method of fabricating the same are provided. The semiconductor device includes a substrate, an isolation structure, an outer structure, and a gate structure. The isolation structure is disposed on the substrate. The outer structure surrounds a sidewall of the isolation structure. The gate structure surrounds a central part of the outer structure, so that the central part covered by the gate structure becomes a channel region, and the outer structure at both sides of the central part respectively becomes a source region and a drain region.
