    摘要: An ion source that may be used to introduce a dopant material into the arc chamber is disclosed. A component containing the dopant material is disposed in the path of an etching gas, which also enters the arc chamber. In some embodiments, the dopant material is in liquid form, and the etching gas travels through the liquid. In other embodiments, the dopant material is a solid material. In some embodiments, the solid material is formed as a porous structure, such that the etching gas flows through the solid material. In other embodiments, one or more components of the ion source are manufactured using a material that includes the dopant material, such that the etching gas etches the component to release the dopant material.

    摘要: An ion source having a thermally isolated repeller is disclosed. The repeller comprises a repeller disk and a plurality of spokes originating at the back surface of the repeller disk and terminating in a post. In certain embodiments, the post may be hollow through at least a portion of its length. The use of spokes rather than a central stem may reduce the thermal conduction from the repeller disk to the post. By incorporating a hollow post, the thermal conduction is further reduced. This configuration may increase the temperature of the repeller disk by more than 100° C. In certain embodiments, radiation shields are provided on the back surface of the repeller disk to reduce the amount of radiation emitted from the sides of the repeller disk. This may also help increase the temperature of the repeller. A similar design may be utilized for other electrodes in the ion source.

    摘要: An ion source with a crucible is disclosed. In some embodiments, the crucible contains a solid dopant material, such as a metal. A porous wicking tip is disposed in the crucible in contact with the solid dopant material. The porous wicking tip may be a tube with one or more interior conduits. Alternatively, the porous tip may be two concentric cylinders with a plurality of rods disposed in the annular ring between the two cylinders. Alternatively, the porous tip may be one or more foil layers wound together. In each of these embodiments, the wicking tip can be used to control the flow rate of molten dopant material to the arc chamber.

    摘要: An insulator that has a helical protrusion spiraling around the shaft is disclosed. A lip is disposed on the distal end of the helical protrusion, creating regions on the shaft that are shielded from material deposition by the lip. By proper sizing of the threads, the helical protrusion and the lip, the line-of-sight to the interior wall of the shaft can be greatly reduced. This results in longer times before failure. This insulator may be used in an ion implantation system to physically and electrically separate two components.

    摘要: An insulator that has a lattice is disclosed. The insulator may have a shaft with two ends. The lattice may be disposed on the outer surface of the shaft. In some embodiments, one or more sheaths are used to cover portions of the shaft. A lattice may also be disposed on the inner wall and/or outer walls of the sheaths. The lattice serves to increase the tracking length between the two ends of the shaft. This results in longer times before failure. This insulator may be used in an ion implantation system to physically and electrically separate two components.
