发明名称 Method of manufacture of constant groove depth pads
摘要 Processing pads for mechanical and/or chemical-mechanical planarization or polishing of substrates in the fabrication of microelectronic devices, methods for making the pads, and methods, apparatus, and systems that utilize and incorporate the processing pads are provided. The processing pads include grooves or other openings in the abrading surface containing a solid or partially solid fill material that can be selectively removed as desired to maintain the fill at an about constant or set distance from the abrading surface of the pad and an about constant depth of the pad openings for multiple processing and conditioning applications over the life of the pad.
