Abstract: Disclosed is a method of manufacturing integrated circuit chips that partially joins an integrated circuit wafer to a supporting wafer at a limited number of joining points. Once joined, the integrated circuit wafer is chemically-mechanically polished to reduce the thickness of the integrated circuit wafer. Then, after reducing the thickness of the integrated circuit wafer, the invention performs conventional processing on the integrated circuit wafer to form devices and wiring in the integrated circuit wafer. Next, the invention cuts through the integrated circuit wafer and the supporting wafer to form chip sections. During this cutting process, the integrated circuit wafer separates from the supporting wafer in chip sections where the integrated circuit wafer is not joined to the supporting wafer by the joining points.

Abstract: The invention includes a field effect transistor (FET) on an insulator layer, and integrated circuit (IC) on SOI chip including the FETs and a method of forming the IC. The FETs include a thin channel with raised source/drain (RSD) regions at each end on an insulator layer, e.g., on an ultra-thin silicon on insulator (SOI) chip. Isolation trenches at each end of the FETs, i.e., at the end of the RSD regions, isolate and define FET islands. Insulating sidewalls at each RSD region sandwich the FET gate between the RSD regions. The gate dielectric may be a high K dielectric. Salicide on the RSD regions and, optionally, on the gates reduce device resistances.
