Abstract (en)

A chemical mechanical polishing apparatus (30) includes a substrate holder (40) to hold a substrate (50), a continuous polishing belt (60), and a backing member (66). The polishing belt includes a first layer formed of a fixed-abrasive polishing material (22) and having a first side, and a second layer formed of a flexible membrane material (20) and having a second side. The belt is configured so that in use the first side of the belt contacts at least a portion of the substrate held by the substrate holder while the membrane is moving in a first direction in a generally linear path relative to the substrate. The backing member (66) is positioned on the second side of the membrane. <IMAGE>
