摘要:
A smart polishing media assembly is provided, along with a polishing system and a method for using the same. In one embodiment, the smart polishing media assembly includes a memory device coupled to a polishing material. The polishing material may be in pad, web or belt form. The memory device generally stores at least one material information, historical use information, and/or conditioning information of the polishing material.
摘要:
A polishing article and method for manufacturing a polishing article for use in a chemical mechanical polishing process is disclosed. The polishing article has a plurality of polishing material tiles separated by grooves formed in or through a polishing material and may be adhesively bound to a base film. The polishing article may include various polygonal tiles and oval shapes formed in the polishing material which allow enhanced slurry retention and ease in rolling from a polishing material supply roll and onto a take-up roll in a web type platen assembly. The polishing article may also include an upper carrier film adapted to minimize delaminating stress placed in an area of the polishing article that is not adapted for polishing. A method and apparatus for manufacturing the various embodiments of the polishing article and a replacement supply roll are also disclosed.
摘要:
A polishing system is described. The polishing system includes a polishing layer, and a subpad supporting the polishing layer, where the subpad has a spiral groove formed therein.

摘要:
A polishing apparatus is described. The polishing apparatus includes a rotatable platen, a drive mechanism to incrementally advance a polishing sheet having a polishing surface in a linear direction across the platen, a subpad on the platen to support the polishing sheet, the subpad having a groove formed therein, and a vacuum source connected to the groove of the subpad and configured to apply a vacuum sufficient to pull portions of the polishing sheet into the groove of the subpad to induce a groove in the polishing surface.
摘要:
A method is described. The method includes contacting a non-solid material to a non-linear edge of a sheet of polishing material, and causing the non-solid material to solidify to form a window that contacts the non-linear edge of the polishing material.
摘要:
A polishing article is described. The polishing article includes an elongated polishing layer, and a transparent carrier layer supporting the polishing layer, where the transparent carrier layer has a projection extending into an aperture in the polishing layer to provide a transparent window in the polishing layer.
摘要:
A method is described. The method includes supporting a polishing sheet having a polishing surface on a subpad having a recess formed therein, applying a vacuum to the recess sufficient to pull portions of the polishing sheet into the recess to induce a recess in the polishing surface, positioning a substrate in a carrier head over the recess in the polishing surface, and lifting the substrate away from the polishing surface while the substrate is positioned over the recess.
摘要:
A polishing article is described. The polishing article includes a linear polishing sheet having a linear transparent portion, wherein the linear transparent portion is formed from a material that has the flexibility to pass around a radius of about 2.5 inches without cracking.
摘要:
A polishing pad for use in a chemical mechanical polishing system is provided. The pad comprises a patterned surface having slurry distribution/retaining grooves formed therein. The slurry distribution/retaining grooves include a uniform or random pattern of non-continuous or obstructed groove segments adapted to inhibit slurry or other fluids from flowing off of the pad during operation.
