Abstract:
1. In an ion implantation system having an ion source maintained at a high electric potential, a grounded end station adapted for holding substrates and a plurality of extraction electrodes accelerating the ions from a source head and directing an ion beam onto the substrates of the end station, the improvement comprising: an insulator disposed between a first component being a high voltage component and a second component being a lower voltage component or a component maintained at ground, the insulator comprising an inner cylindrical body surrounded by an outer cylindrical body with a gap therebetween, said inner cylindrical body oriented such that its axis extends from said first component to said second component, and the outer cylindrical body having opposed ends, one of the ends radially coupled to the inner cylindrical body, wherein the inner cylindrical body is longer than the outer cylindrical body and includes opposed end faces, each in confronting relation with and contacting and terminating at an exterior of a respective one of said first and second components and wherein each of said first and second components comprise electrodes, and wherein the insulator comprising the inner cylindrical body and the outer cylindrical body is a single uninterrupted and inseparable unit and the inner cylindrical body includes an axially central portion being completely diametrically solid.
