摘要: A system for controlling and monitoring a rate of flow of a fluid, such as a CMP slurry, comprising a pump for pumping the slurry; a flow meter for monitoring the rate of flow of the slurry; and a controller operably connected to the flow meter and the pump. The controller receives signals from the flow meter indicating the rate of flow of the slurry and controls the operational speed of the pump responsive to the flow meter signals. A degasser equipped with a level sensor may be further provided in the system for removing gas bubbles from the slurry.

摘要: A DMHC (dual mode hybrid control) system and method which facilitates enhanced control in the delivery of polishing slurry to a CMP (chemical mechanical polishing) apparatus. The DMHC comprises a linear table and a PID (proportional integrated differential) controller operably connected to a slurry pump provided in a slurry flow conduit which delivers the polishing slurry to the CMP apparatus. A bubble trap and a flowmeter provided in the slurry flow conduit downstream of the slurry pump are operably connected to the PID controller, and the CMP apparatus is located downstream of the flowmeter.
