Abstract:
A method of planarizing a microelectronic substrate assembly, comprising:cutting a cylindrical body of pad material to form a seamless web having a desired thickness, wherein cutting further comprises slicing the 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; pressing the substrate assembly against a planarizing surface of the seamless web by supporting the web with a table defining a planarizing zone and applying a downforce against the substrate; moving at least one of the substrate assembly with respect to the web for removing material from the substrate; and sliding the web across the table to move one portion of the web out of the planarizing zone and to move another portion of the web into the planarizing zone without removing the web from the table.
