Abstract
Some embodiments relate to a semiconductor device. The semiconductor device includes a layer disposed over a substrate. A conductive body extends through the layer. A plurality of bar or pillar structures are spaced apart from one another and laterally surround the conductive body. The plurality of bar or pillar structures are generally concentric around the conductive body.
