    Abstract: A method and apparatus for planarizing a microelectronic substrate. In one embodiment, the apparatus can include a membrane formed from a compressible, flexible material, such as neoprene or silicone, and having a first portion with a thickness greater than that of a second portion. The membrane can be aligned with the microelectronic substrate to bias the microelectronic substrate against a planarizing medium such that the first portion of the membrane biases the microelectronic substrate with a greater downward force than does the second portion of the membrane. Accordingly, the membrane can compensate for effects, such as varying linear velocities across the face of the substrate that would otherwise cause the substrate to planarize in a non-uniform fashion or, alternatively, the membrane can be used to selectively planarize portions of the microelectronic substrate at varying rates.

  • Patent number: 5413520
    Abstract: The conical internal teeth (7) of a spur gear grinding tool (2) mesh with the teeth (6) of a spur gear workpiece (1) or a dressing spur gear. The tool axis (4) forms an acute angle (.gamma.) with the workpiece axis (3). To grind and to dress, the spur gear tool (2) is fed relative to the workpiece (1) in the direction of the tool axis (4). In this manner an optimal tooth meshing between the tool (2) and the workpiece (1) over a wide dressing range and a constant finishing are achieved.
