Patent ID: 7332778

Claim:
A Silicon on Insulator (SOI) device, comprising: at least one isolating layer made of a dielectric material at least one silicon substrate arranged on said isolating layer and having a buried passivation layer, which is in particular oxide-based; at least one component integrated in the silicon substrate, which component has at least one slightly doped zone, and is a lateral transistor, as well as at least a first, in particular planar, metallization region arranged between the isolating layer and the component, and at least a second, in particular planar, metallization region arranged on the side of the silicon substrate facing away from the isolating layer, in the area of the component, on the buried passivation layer of the substrate, wherein a first field plate is defined in the first metallization region in the area between the isolating layer and the slightly doped zone of the component, and a second field plate is defined in the second metallization region in the area of the slightly doped zone of the component.
