Abstract
In one embodiment, an integrated circuit includes an array of active structures, an array of dummy structures and multiple well-tap structures. The array of dummy structures surrounds the array of active structures. The well-tap structures may be interposed between the array of active structures and the array of dummy structures. In one embodiment, each of the well-tap structures may include a well, a diffusion region and a gate-like structure. The well may be formed in a substrate and is of a first doping type. The diffusion region may be formed in the well and is also of the first doping type. The gate-like structure may be formed above the substrate and adjacent to the diffusion region.
