  • Patent number: 6107203
    Abstract: A chemical mechanical planarization tool (21) comprises a platen (22), a wafer carrier arm (31), a carrier assembly (37), a conditioning arm (28), and an end effector (33). A slurry delivery system (51) reduces waste by providing polishing chemistry at a minimum required delivery rate that ensures consistent wafer planarization. The slurry deliver system comprises a check valve (52), a diaphragm pump (53), a check valve (54), a back pressure valve (55), and a dispense bar (58). The diaphragm pump (53) provides a precise volume of polishing chemistry with each pump cycle, independent of input pressure. The check valves (52,54) prevent reverse flow of the polishing chemistry through the diaphragm pump (53). Back pressure valve (55) creates a pressure differential across the check valve (54) to prevent the flow of polishing chemistry during a downstroke of the diaphragm pump (53). The polishing chemistry is dispensed onto a polishing media from dispense bar (58).

  • Patent number: 5967379
    Abstract: A container for dispersing liquid through a dispenser is described. The container has a resealable outlet which has an outlet passageway in a tube and a stop wedged in the passageway to seal the liquid in the container. The passageway is accessible beneath the stop by a dispenser peg for insertion in the tube to push the stop inward toward the interior of the container. A means for containing the stop is adjacent the passageway inlet. The stop reseals the passageway by covering the passageway inlet after a dispenser peg is removed from the passageway.

    Abstract: A dispenser is described having a support for the container to be filled, a source of liquid and a switch controlling the flow of liquid into the container. The container is supported by a support which urges the container up or down. The switch is operated by the container such that when the container is empty it urges against a resilient mechanism which activates the switch. When the container is filled its weight overcomes the resilient mechanism.
