A semiconductor device and method for fabricating a semiconductor device is disclosed. An exemplary semiconductor device includes a substrate including a metal oxide device. The metal oxide device includes first and second doped regions disposed within the substrate and interfacing in a channel region. The first and second doped regions are doped with a first type dopant. The first doped region has a different concentration of dopant than the second doped region. The metal oxide device further includes a gate structure traversing the channel region and the interface of the first and second doped regions and separating source and drain regions. The source region is formed within the first doped region and the drain region is formed within the second doped region. The source and drain regions are doped with a second type dopant. The second type dopant is opposite of the first type dopant.
