    Abstract: The application of gas cluster ion beam (GCIB) technology in order to modify the surface of a surgical implant such as the components of an artificial hip joint, thereby substantially reducing wear debris and osteolysis complications is disclosed. The approach of the surface modification comprises an atomic level surface smoothing utilizing GCIB to super smooth the femoral heads and/or the surfaces of the acetabular cups to reduce frictional wear at the interface of the bearing surfaces. A reduction in polyethylene debris and metal debris by GCIB smoothing on one or both bearing surfaces of a surgical implant reduces osteolysis, results in a substantial cost savings to the healthcare system, and reduces patient pain and suffering.

    Abstract: A gas cluster ion beam (GCIB) etching apparatus having a system for producing a gas cluster ion beam utilized to controllably etch a substrate. The gas cluster ion beam is initially directed along a preselected longitudinal axis. A portion of the GCIB etching apparatus is operably connected to the beam producing system and contains the substrate to be etched when impacted by said gas cluster ion beam. The portion of the GCIB etching apparatus includes a system for directing the gas cluster ion beam in a direction offset from the preselected longitudinal axis while permitting unwanted ionizing radiation to remain directed along the longitudinal axis. A substrtate holder is located within a portion of the GCIB etching apparatus for positioning the substrate in line with the offset gas cluster ion beam during the etching process, and the unwanted ionizing radiation being substantially prevented from impinging upon the substrate during the etching process.

    Abstract: A semiconductor thin film and glass stratum laminate is formed by depositing a semiconductor thin film onto a temporary substrate having a carbon coating to which the film adheres. Processing of the semiconductor thin film for selected performance characteristics is accomplished while the film is affixed to the temporary substrate. The processed thin film is transferred and electrostatically bonded to the glass stratum by exposure to a thermal environment at or below the softening point of the glass stratum and by application of an electric potential across the thin film and glass. The bonded thin film and glass stratum laminate is separated from the temporary substrate.
