    摘要: An apparatus for reducing non-uniform stretch of a belt used in the CMP system is disclosed. The belt that may be used with the apparatus extends between a first roller and a second roller to define a belt loop with an inner surface and an outer surface to be used for CMP. The apparatus includes a compensating roller that has a first end and a second end where the first end and second end extends a width of the belt. The first end and the second end have a first diameter. The center of the roller has a second diameter that is less than the first diameter. The compensating roller has a symmetrically tapered shape that extends between each of the first end and second end to the center. The compensating roller is positioned inside of the belt loop, and is applied to the inner surface of the belt loop to reduce non-uniform stretch of the belt.

    摘要: Methods for fabricating semiconductor structures having LowK dielectric properties are provided. In one example, a copper dual damascene structure is fabricated in a LowK dielectric insulator including forming a capping film over the insulator before features are defined therein. After the copper is formed in the features, the copper overburden is removed using ultra-gentle CMP, and then the barrier is removed using a dry etch process. Following barrier removal, a second etch is performed to thin the capping film. The thinning is configured to reduce the thickness of the capping film without removal, and thereby reducing the K-value of the LowK dielectric structure.

    摘要: A first embodiment of the invention relates to a method for evaluating the quality of structures on an integrated circuit wafer. Test structures formed on either on the integrated or on a test wafer are exposed to an electron beam and an electron-beam activated chemical etch. The electron-beam activated etching gas or vapor etches the test structures, which are analyzed after etching to determine a measure of quality of the test structures. The measure of quality may be used in a statistical process control to adjust the parameters used to form device structures on the integrated circuit wafer. The test structures are formed on an integrated circuit wafer having two or more die. Each die has one or more integrated circuit structures. The test structures are formed on scribe lines between two or more adjacent die. Each test structure may correspond in dimensions and/or composition to one or more of the integrated circuit structures.
