摘要： A method controllably and sustainably creates an upwardly directed gradient of dropping temperatures in a wet treatment tank between a cooled and face down workpiece (e.g., an in-process semiconductor wafer) and a lower down heat source. A thermal fluid upwell containing thermally collapsible bubbles is then directed from the heat source to the face down workpiece. In one class of embodiments, bubble collapse energy release and/or bubble collapse locations are controlled so as to avoid exposing delicate features of the to-be-treated surface to damaging forces. In one class of embodiments the wet treatment includes ultra-cleaning of the work face. Cleaning fluids that are essentially free of predefined contaminates are upwelled to the to-be-cleaned surface and potentially contaminated after-flows are convectively directed away from the workpiece so as to prevent recontamination of the workpiece.

摘要： A semiconductor processing system is provided. The semiconductor processing system includes a first sensor configured to isolate and measure a film thickness signal portion for a wafer having a film disposed over a substrate. A second sensor is configured to detect a film thickness dependent signal in situ during processing, i.e. under real process conditions and in real time. A controller configured to receive a signal from the first sensor and a signal from the second sensor. The controller is capable of determining a calibration coefficient from data represented by the signal from the first sensor. The controller is capable of applying the calibration coefficient to the data associated with the second sensor, wherein the calibration coefficient substantially eliminates inaccuracies introduced to the film thickness dependent signal from the substrate. A method for calibrating an eddy current sensor is also provided.

摘要： A method for making a semiconductor device is provided. The method includes forming transistor structures on a substrate and forming interconnect metallization structures in a plurality of levels through depositing a sacrificial layer. A dual damascene process is performed to etch trenches and vias, and filling and planarizing the trenches and vias. The sacrificial layer is etched throughout the plurality of levels of the interconnect metallization structures, thus leaving a voided interconnect metallization structure. The voided interconnect metallization structure is filled with low K dielectric material, thus defining a low K dielectric interconnect metallization structure.
