Abstract:
A method for conditioning a planarizing medium used for planarizing a semiconductor substrate, the method comprising:engaging a conditioning body with the planarizing medium, wherein the conditioning body is coupled to a support member for supporting the conditioning body relative to the planarizing medium; moving at least one of the conditioning body and the planarizing medium relative to the other of the conditioning body and the planarizing medium to remove material from the planarizing medium; and maintaining an approximately constant frictional force between the conditioning body and the planarizing medium by selecting a target frictional force, detecting a force between the conditioning body and the planarizing medium by measuring a force transmitted to the support member by the conditioning body, and adjusting a relative velocity between the conditioning body and the planarizing medium until the force is approximately equal to the target frictional force.
