Abstract:
A method for removing material from a microelectronic substrate, comprising:inclining a planarizing surface of a non-continuous polishing pad relative to horizontal, the polishing pad including an elongated web coupled at one end to a supply roll and at an opposite end to a take-up roll; advancing the web over a platen from the supply roll to the take-up roll; engaging the microelectronic substrate with the planarizing surface of the polishing pad while the polishing pad is inclined relative to horizontal; passing a flow of ventilation gas along an inclined path generally parallel to the planarizing surface; and moving at least one of the polishing pad and the microelectronic substrate relative to the other to remove material from the microelectronic substrate while the polishing pad is inclined relative to horizontal and without moving the polishing pad in a continuous loop between two rollers.
