ABSTRACT:
The present invention is directed toward carrier assemblies, planarizing machines with carrier assemblies, and methods for mechanical and/or chemical-mechanical planarization of micro-device workpieces. In one embodiment, a carrier assembly for holding a microelectronic workpiece comprises a head, a backing assembly in the head, and a barrier. The head includes a chamber, a pneumatic line in fluid communication with the chamber through which a pneumatic fluid passes, and a retaining member defining a perimeter portion of a workpiece cavity. The backing assembly is positioned in the head, and the backing assembly can include a plate in the chamber and a diaphragm on one side of the plate. The diaphragm defines a backside portion of the workpiece cavity. The barrier is positioned in the chamber and/or the pneumatic line. The barrier is configured to inhibit contaminants from back-flowing into at least a portion of the pneumatic line. The barrier, for example, can be a membrane or a filter that inhibits or prevents matter such as particulates and/or fluids from passing along at least a portion of the pneumatic line. As a result, when the diaphragm rips, the barrier prevents the planarizing solution from fouling the pneumatic line and/or a rotary coupling.
