Abstract:
A planarizing machine, comprising:a table defining a planarizing zone; a supply roller proximate to the table; a take-up roller proximate to the table, at least one of the supply roller and the take-up roller being a drive roller; a seamless pad including a web formed from a single molded body of pad material, the web having a planarizing surface and a backside opposite from the planarizing surface, the pad further comprising a backing ply attached to the backside of the web, and the web further comprises a polymeric matrix material and a plurality of abrasive particles fixed to the polymeric material, the abrasive particles being fixed to the polymeric material at least at the planarizing surface, and further wherein the web has a first portion wrapped around the supply roller, a second portion on the table in the planarizing zone, and a third portion wrapped around the take-up roller, the drive roller rotating a selected distance to selectively slide the web across the table; and a carrier assembly having a substrate holder positionable over the web, wherein at least one of the substrate holder or the web moves relative to the other to translate a substrate with respect to the web.
