Abstract

An ion source for an ion implantation system has a plurality of arc chambers. The ion source forms an ion beam from a respective one of the plurality of arc chambers based on a position of the respective one of the plurality of arc chambers with respect to a beamline. The arc chambers are coupled to a carrousel that translates or rotates the respective one of the plurality of arc chambers to a beamline position associated with the beamline. One or more of the plurality of arc chambers can have at least one unique feature, or two or more of the plurality of arc chambers can be generally identical to one another.

Abstract

An endless media filtration system includes a housing with a pool forming assembly mounted between a pair of side walls. The pool forming assembly includes a central shaft with two spaced-apart containment discs rotatably mounted on the shaft between the side walls. An endless loop filter media belt is supported on an endless loop carrier belt and includes an upper run which is pressed against the peripheral edges of the discs to form a generally semicircular shaped pool along bottom arcs of the discs. A separation pan is located between upper and lower runs of the carrier belt to direct filtered liquid to one side of the carrier belt and out the bottom of the housing. A backwash assembly includes a first spray rod spraying air through the filter media, a second spray rod spraying water through the filter media, and a third spray rod spraying air through the filter media after the filter media has passed under the second spray rod. The spray rods are oriented on the inward side of the filter belt and spray through the filter belt to remove particulate therefrom. A pair of freely rotatable tracking wheels engage the filter media belt and stretch it taut between the tracking wheels to remove wrinkles from the media belt.
