Abstract
In some embodiments, an integrated circuit is provided. The integrated circuit may include an inner ring-shaped isolation structure that is disposed in a semiconductor substrate. Further, the inner-ring shaped isolation structure may demarcate a device region. An inner ring-shaped well is disposed in the semiconductor substrate and surrounds the inner ring-shaped isolation structure. A plurality of dummy gates are arranged over the inner ring-shaped well. Moreover, the plurality of dummy gates are arranged within an interlayer dielectric layer.
