Claim Text:
1. An ion implantation system, comprising: an ion implantation apparatus configured to direct an ion beam toward a process chamber, wherein the process chamber has a vacuum environment associated therewith at a vacuum pressure; a first dual load lock assembly and a second dual load lock assembly, wherein each of the first dual load lock assembly and second dual load lock assembly respectively comprises a first chamber and a second chamber, wherein respective internal volumes of each first and second chamber are generally isolated from one another and share a common wall therebetween, and wherein each of the first chamber and second chamber has a respective vacuum door and atmospheric door, wherein each respective vacuum door is configured to provide selective fluid communication between the respective first chamber or second chamber and the vacuum environment, and wherein each respective atmospheric door is configured to provide selective fluid communication between the respective first chamber or second chamber and an atmospheric environment having an atmospheric pressure associated therewith, and wherein each first chamber has a pre-heat apparatus associated therewith, wherein the pre-heat apparatus is configured to heat a workpiece disposed within the respective first chamber, and wherein each second chamber has a post-cool apparatus associated therewith, wherein the post-cool apparatus is configured to cool the workpiece disposed within the respective second chamber; and a controller configured to activate each respective pre-heat apparatus to transmit heat energy to the respective workpiece at the atmospheric pressure, therein raising a temperature of the respective workpiece to a first predetermined temperature, and wherein the controller is further configured to activate each respective post-cool apparatus to cool the respective workpiece to a second predetermined temperature.
