Patent ID: 8368309

Claim:
An ion extraction electrode assembly constructed for use in an ion implantation system, the ion implantation system having an ion source that has a low temperature operating mode for ionizing gasses and vapors at relatively low temperatures below 400° C., the ion extraction electrode assembly comprising: a temperature controlled extraction electrode comprising a suppression electrode element and a ground electrode element, said extraction electrode configured to extract ions from the ion source as an ion beam for transport to a surface for ion implantation, and a temperature controllable heater disposed between said suppression electrode element and said ground electrode element, said heater configured to maintain the extraction electrode at a temperature sufficient to prevent condensation on the electrode of gases or vapors, said extraction electrode and said controllable heater configured to form an assembly, wherein the ion extraction electrode is capable of being heated to about 150 C. for alternative operation with decaborane and octadecaborane.
