Abstract
Aspects of the disclosure provide a semiconductor device and method of manufacturing. Embodiments of the disclosure enable placing of protective structures without modifying spacing rules. The device includes a first device region defined above a substrate, the first device region being isolated from the substrate by a buried insulating layer. The first device region includes a first power rail, a first signal line traversing at least a first portion of the first device region, and a first plurality of edge cells positioned in the substrate adjacent the first device region. A first edge cell includes a substrate contact connecting the first power rail to the substrate and a first signal line antenna diode connecting the first signal line to the substrate.
