Abstract:
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 the first planarizing medium with a first support surface of a platen unit while supporting the second planarizing medium with a second support surface of the platen unit facing generally opposite the first support surface; engaging a first microelectronic substrate with the first planarizing medium and engaging a second microelectronic substrate with the second planarizing medium while the planarizing media 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.
