    摘要: A cold trap filter and method is provided for filtering chemical species from a vacuum system of an ion implantation system. A canister is in fluid communication with an exhaust of a high vacuum pump and an intake of a roughing pump used for evacuating an ion source chamber. One or more paddles are positioned within the canister, wherein each paddle has a cooling line in fluid communication with a coolant source. The coolant source passes a coolant through the cooling line, thus cooling the one or more paddles to a predetermined temperature associated with a condensation or deposition point of the chemical species, therein condensing or depositing the chemical species on the paddles while not interfering with a vacuum capacity of the high vacuum and roughing pumps. The paddles can also be electrically biased to electrostatically attract the chemical species to the paddles in one or more biasing steps.

    摘要: An ion implantation system provides ions to a workpiece positioned in a vacuum environment of a process chamber on a cooled chuck. A pre-chill station within the process chamber has a chilled workpiece support configured to cool the workpiece to a first temperature, and a post-heat station within the process chamber, has a heated workpiece support configured to heat the workpiece to a second temperature. The first temperature is lower than a process temperature, and the second temperature is greater than an external temperature. A workpiece transfer arm is further configured to concurrently transfer two or more workpieces between two or more of the chuck, a load lock chamber, the pre-chill station, and the post-heat station.
