Patent ID: 7144304

Claim:
A method for removing material from two microelectronic substrates, comprising: inclining a first planarizing surface of a first planarizing medium relative to horizontal and inclining a second planarizing surface of a second planarizing medium relative to horizontal; supporting a first microelectronic substrate with a first portion of a substrate carrier and supporting a second microelectronic substrate with a second portion of the substrate carrier; positioning the substrate carrier between the first and second planarizing media to engage the first microelectronic substrate with the first planarizing surface and engage the second microelectronic substrate with the second planarizing surface while the planarizing surfaces are inclined relative to horizontal; and moving at least one of the first planarizing medium and the first microelectronic substrate relative to the other and moving at least one of the second planarizing medium and the second microelectronic substrate relative to the other to remove material from the microelectronic substrates while the planarizing media are inclined relative to horizontal.
