Abstract
A semiconductor device and a method of fabricating the same includes a substrate, two first field regions, a gate structure, a first isolation structure, and a plurality of second field regions. The two first field regions are disposed in the substrate, and the gate structure is disposed on the substrate, between the two first field regions. The first isolation structure is disposed in one of the two first field regions, under one side of the gate structure. The second field regions are disposed in the substrate, wherein the second field regions are separately and sequentially arranged to surround an outer periphery of the one of the two first field regions.
