Abstract:
A planarizing apparatus for planarizing microelectronic-device substrate assemblies, comprising:a platform upon which a substrate assembly can be mounted and held stationary during planarization; a turret assembly positioned over the platform, the turret assembly being translatable in a plane at least substantially parallel to the substrate assembly and rotatable about a turret rotation axis in a first rotational direction, and the turret assembly having a first station spaced apart from the turret rotation axis and a second station spaced apart from the turret rotation axis, the first and second stations orbiting about the turret rotation axis as the turret rotates in the first rotational direction; a first pad carrier attached to the turret assembly at the first station that rotates in the first rotational direction about a first pad rotation axis through the first station; a first pad attached to the first pad carrier; a second pad carrier attached to the turret assembly at the second station that rotates in a second rotational direction counter to the first rotational direction about a second pad rotation axis through the second station; and a second pad attached to the second pad carrier.
