Abstract:
A semiconductor device is made by forming an oxide layer over a substrate and forming a first conductive layer over the oxide layer. The first conductive layer is connected to ground. A second conductive layer is formed over the first conductive layer as a plurality of segments. A third conductive layer is formed over the second conductive layer as a plurality of segments. If the conductive layers are electrically isolated, then a conductive via is formed through these layers. A first segment of the third conductive layer operates as a first passive circuit element. A second segment operates as a second passive circuit element. A third segment is connected to ground and operates as a shield disposed between the first and second segments. The shield has a height at least equal to a height of the passive circuit elements to block cross-talk between the passive circuit elements.
