Abstract
In one embodiment, an isolation device has a substrate, a metal plate, a conductive layer, first and second isolation layers are disclosed. The conductive layer may be formed within the substrate. The conductive layer may be arranged coupled to the metal plate, so as to receive a capacitively coupled signal from the metal plate. The first and second isolation layers may be sandwiched between the metal plate and the conductive layer. In another embodiment, an isolation device comprising a semiconductor substrate, a topmost metal layer and a plurality of additional metal layers is disclosed. The isolation device further comprises an isolation capacitor formed using the topmost metal layer and a conductive layer coupled to at least one of the plurality of additional metal layers.
