Pads for chemical mechanical planarization tools, chemical mechanical planarization tools, and related methods
Abstract:
A pad for chemical mechanical planarization comprises a material having a major surface, and asperities extending from the major surface, a ratio between a length and a width of each of the asperities greater than about 2:1, and an included angle between a leading surface of at least some asperities and the major surface greater than about 90°. Related pads, tools for chemical mechanical planarization, and related methods are also disclosed.
