摘要: Techniques for removing molecular fragments from an ion implanter are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for removing molecular fragments from an ion implanter. The apparatus may comprise a supply mechanism configured to couple to an ion source chamber and to supply a feed material to the ion source chamber. The apparatus may also comprise one or more hydrogen-absorbing materials placed in a flow path of the feed material, to prevent at least one portion of hydrogen-containing molecular fragments in the feed material from entering the ion source chamber.

摘要: Techniques for measuring energy contamination using time-of-flight (TOF) sensor are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for detecting energy contamination in an ion beam using time-of-flight comprising directing an ion beam towards an entrance of a sensor, wherein the ion beam may include charged particles and neutral particles, blocking the ion beam periodically from entering the sensor and allowing a pulse of the ion beam to enter the sensor periodically using a gate mechanism, separating the charged particles and the neutral particles of the ion beam pulse based at least in part upon different transit times over a distance caused by variations in at least one of mass and energy associated with the charged particles and the neutral particles, and detecting at least one of the charged particles and the neutral particles separately at a detector based at least in part upon the different transit times.

摘要: Techniques for temperature-controlled ion implantation are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for temperature-controlled ion implantation. The apparatus may comprise a platen to hold a wafer in a single-wafer process chamber during ion implantation, the platen including: a wafer clamping mechanism to secure the wafer onto the platen and to provide a predetermined thermal contact between the wafer and the platen, and one or more heating elements to pre-heat and maintain the platen in a predetermined temperature range above room temperature. The apparatus may also comprise a post-cooling station to cool down the wafer after ion implantation. The apparatus may further comprise a wafer handling assembly to load the wafer onto the pre-heated platen and to remove the wafer from the platen to the post-cooling station.
