Abstract:
In the fabrication of microelectronic devices, a method of planarizing a microelectronic substrate assembly, comprising:slicing a cylindrical body of pad material along a cutting line at least substantially parallel to a longitudinal centerline of the body and at a radial depth inward from an exterior surface of the body toward the centerline to form a polishing pad; pressing the substrate assembly against a planarizing surface of the pad of the pad having a length to that extends beyond a planarizing table, the length being wrapped around at least one roller when the pad is mounted to a planarizing machine, the pad being a seamless web formed from a single molded body of the pad material; and moving at least one of the pad assembly or the pad with respect to the other by translating at least one of the substrate or the pad.
