Abstract: Various embodiments of a semiconductor processing fluid delivery system and a method delivering a semiconductor processing fluid are provided. In aspect, a system for delivering a liquid for performing a process is provided that includes a first flow controller that has a first fluid input coupled to a first source of fluid and a second flow controller that has a second fluid input coupled to a second source of fluid. A controller is provided for generating an output signal to and thereby controlling discharges from the first and second flow controllers. A variable resistor is coupled between an output of the controller and an input of the second flow controller whereby the output signal of the controller and the resistance of the variable resistor may be selected to selectively control discharge of fluid from the first and second flow controllers.

Abstract: An off-line tool for breaking in pad conditioning disks used in a chemical mechanical polishing (CMP) system. The off-line tool comprises a platen having a first surface for -holding a polishing pad and a motor for rotating the polishing pad. The motor is coupled to the platen via a first drive shaft. The off-line tool further comprises a mechanical drive assembly for holding a second drive shaft in a position proximate the first surface of the platen and a first break-in head removably attached to the second drive shaft. The first break-in head receives a first pad conditioning disk and the second drive shaft moves the first break-in head toward the platen, thereby pressing the first pad-conditioning disk against the polishing pad on the platen.

Abstract: An apparatus for breaking in new pad conditioning disks for use in a chemical mechanical polishing (CMP) system that polishes a semiconductor wafer by pressing the semiconductor wafer against a moving polishing pad. The apparatus comprises a break-in head that is removably attached to a drive shaft to which a polishing head that holds the semiconductor wafer is normally attached. The break-in head holds multiple pad conditioning disks and presses the plurality of pad conditioning disks against the moving polishing pad. The break-in head comprises a drive mechanism for rotating the multiple pad conditioning disks. The drive mechanism is coupled to the drive shaft and rotates the multiple pad conditioning disks by translating a rotating motion of the drive shaft into rotating motions of the multiple pad conditioning disks.
