Abstract

Thermally isolated captive features disposed in various components of an ion implantation system are disclosed. Electrodes, such as repellers and side electrodes, may be constructed with a captive feature, which serves as the electrode stem. The electrode stem makes minimal physical contact with the electrode mass due to a gap disposed in the interior cavity which retains the flared head of the electrode stem. In this way, the temperature of the electrode mass may remain higher than would otherwise be possible as conduction is reduced. Further, this concept can be applied to workpiece holders. For example, a ceramic platen is manufactured with one or more captive fasteners which are used to affix the platen to a base. This may minimize the thermal conduction between the platen and the base, while providing an improved mechanical connection.
