Abstract:
A method for planarizing a semiconductor substrate with a planarizing machine, the planarizing machine having a platen, a first planarizing medium, and a carrier to engage the semiconductor substrate with the first planarizing medium, the method comprising:positioning the first planarizing medium adjacent the platen; applying a vacuum to a plurality of apertures in a surface of the platen to form an at least partially gas-tight seal between the first planarizing medium and the platen; moving at least one of the platen and the carrier relative to the other of the platen and the carrier to remove material from the semiconductor substrate; removing liquid from a fluid drawn through the vacuum apertures; releasing the vacuum; and removing the first planarizing medium from the platen and positioning a second planarizing medium adjacent the platen.
