    Abstract: In one embodiment, a slider includes a substrate, a magnetic head, and a coupling capacitor. In one embodiment, a slider includes a substrate, a magnetic head, and a coupling capacitor configured to AC couple an electronics ground of the slider to the substrate and DC decouple the electronics ground of the slider from the substrate, the coupling capacitor including: a first conductive layer, a gap layer positioned above the first conductive layer, a dielectric layer positioned above the gap layer and the first conductive layer, and a second conductive layer positioned above the dielectric layer. In another embodiment, a method for forming a capacitor includes forming a substrate, forming a first conductive layer above the substrate, forming a gap layer above the first conductive layer, forming a dielectric layer above the gap layer and the first conductive layer, and forming a second conductive layer above the dielectric layer.
