    摘要: Disclosed are embodiments of a semiconductor structure, a design structure for the semiconductor structure and a method of forming the semiconductor structure. The embodiments reduce harmonics and improve isolation between the active semiconductor layer and the substrate of a semiconductor-on-insulator (SOI) wafer. Specifically, the embodiments incorporate a trench isolation region extending to a fully or partially amorphized region of the wafer substrate. The trench isolation region is positioned outside lateral boundaries of at least one integrated circuit device located at or above the active semiconductor layer of the SOI wafer and, thereby improves isolation. The fully or partially amorphized region of the substrate reduces substrate mobility, which reduces the charge layer at the substrate/BOX interface and, thereby reduces harmonics. Optionally, the embodiments can incorporate an air gap between the wafer substrate and integrated circuit device(s) in order to further improve isolation.

    摘要: Device structures with hyper-abrupt p-n junctions, methods of forming hyper-abrupt p-n junctions, and design structures for an integrated circuit containing devices structures with hyper-abrupt p-n junctions. The hyper-abrupt p-n junction is defined in a SOI substrate by implanting a portion of a device layer to have one conductivity type and then implanting a portion of this doped region to have an opposite conductivity type. The counterdoping defines the hyper-abrupt p-n junction. A gate structure carried on a top surface of the device layer operates as a hard mask during the ion implantations to assist in defining a lateral boundary for the hyper-abrupt-n junction.

    摘要: A ground shield is disclosed that includes a ‘cheesed’ metal positioned within a dielectric layer and a metal region positioned within a first metal level over the cheesed metal. The ground shield can have different forms depending on the metal used, and provisions are made to prevent diffusion of copper (Cu) when that is used as the metal in the cheese metal of the ground shield. The ground shield provides a low resistance, very thick metal at a first metal (M1) level for passive RF elements in conjunction with the standard back-end-of-line (BEOL) integration. The invention also includes a method of forming the ground shield.
