摘要： A polishing process in a semiconductor device fabrication process employs a polishing composition in which a gaseous phase is created within the polishing composition. During a polishing process, the gaseous phase dynamically responds to changes in the surface profile of the material undergoing removal by chemical and abrasive action during polishing. The inert gas bubble density dynamically increases in proximity to surface region of the substrate being polished that are prone to dishing and erosion. The increased inert gas bubble density operates to reduce the polish removal rate relative to other regions of the substrate. The dynamic action of the gaseous phase within the polishing composition functions to selectively reduce the localized polish removal rate such that a uniformly smooth and flat polished surface is obtained that is independent of the influence of pattern density during the polishing process.

摘要： An apparatus, system, and method are disclosed for restoring efficiency of a photovoltaic cell. An illumination module illuminates photovoltaic cells so the cells receive a time integrated irradiance equivalent to at least 5 hours of solar illumination. After illumination, an annealing module anneals the photovoltaic cells at a temperature above 90 degrees Celsius for a minimum of 10 minutes. In one embodiment, the illumination module illuminates the photovoltaic cells for a time integrated irradiance equivalent to at least 20 hours of solar illumination. In another embodiment, the illumination module illuminates the photovoltaic cells for a time integrated irradiance equivalent to at least 16 hours of solar illumination while being heated to at least 50 degrees Celsius. In another embodiment, a solar concentrator irradiates the photovoltaic cells in sunlight for at least 10 hours and increases the irradiance of solar illumination on the cells by a factor of 2 to 5.

摘要： A selective conductive cap is deposited on exposed metal surfaces of a metal line by electroless plating selective to exposed underlying dielectric surfaces of a metal interconnect structure. A dielectric material layer is deposited on the selective conductive cap and the exposed underlying dielectric layer without a preclean. The dielectric material layer is planarized to form a horizontal planar surface that is coplanar with a topmost surface of the selective conductive cap. A preclean is performed and a dielectric cap layer is deposited on the selective conductive cap and the planarized surface of the dielectric material layer. Because the interface including a surface damaged by the preclean is vertically offset from the topmost surface of the metal line, electromigration of the metal in the metal line along the interface is reduced or eliminated.

摘要： A method for manufacturing a circuit includes the step of providing a first wiring level comprising first wiring level conductors separated by a first wiring level dielectric material. A first dielectric layer with a plurality of interconnect openings and a plurality of gap openings is formed above the first wiring level. The interconnect openings and the gap openings are pinched off with a pinching dielectric material to form relatively low dielectric constant (low-k) volumes in the gap openings. Metallic conductors comprising second wiring level conductors and interconnects to the first wiring level conductors are formed at the interconnect openings while maintaining the relatively low-k volumes in the gap openings. The gap openings with the relatively low-k volumes reduce parasitic capacitance between adjacent conductor structures formed by the conductors and interconnects.

摘要： A method for manufacturing a photovoltaic solar cell device includes the following. A p-n junction having a first doping density is formed. Formation of the p-n junction is enhanced by introducing a second doping density to form high doped areas for a dual emitter application. The high doped areas are defined by a masking process integrated with the formation of the p-n junction, resulting in a mask pattern of the high doped areas. A metallization of the high doped areas occurs in accordance with the mask pattern of the high doped areas.
