Abstract:
1. A semiconductor-on-insulator structure comprising: an electrically conductive layer located in an excavated insulator region that is excavated on a bottom side of the structure; an insulator layer being located above the electrically conductive layer, and partially vertically coextensive with the electrically conductive layer in the excavated insulator region; an active layer being located above the insulator layer, the active layer comprising an active device with a body and a gate, wherein the gate is located above the body; a handle wafer formed above the active layer; and a body contact physically connecting the electrically conductive layer and the body, the body contact being located in a first portion of the excavated insulator region; wherein the electrically conductive layer couples the body contact to a contact in the active layer, the contact being located in a second portion of the excavated insulator region, the second portion being detached from the first portion.
